By now, you should have finished the Unit 3 VCE Biology exam for 2010. What did you think of the paper? What was hard? What was easy? How do you think you went?
Let us know your thoughts and comments below (please keep them clean!)…cheers
I think it was very hard compared to the 2009 and 2010 ones. The exam questions were very unexpected as I studied for the stuff that wasn’t on the exam and didn’t even know about some things on it. There were new words I never knew about like porins or something. Terrible day today.
i found it really long
there was a lot of reading involved and i didn’t get to finish the last question.
i didnt know what the function of a proin was?
the experiment design was straight forward it had come up many times before on past exams, it was expected.
some questions were confusing for example the hormone x and cell y question.
i had to read the questions more than twice to understand them which wasted time.
It was definately harder than the 2007-2009 exams – the multiple choice in particular were tricker than usual.
And it was really long, and the short answer questions were quite a bit different to those from past years.
it was amazing! i think im a genius. i finished it in 45 minutes. multiple choice was a breezeeee! im expecting study score of 50. no questions asked! some people say im arrogant, i like to think im just prepared and capable. sorry if ur jealous, and not as confident, its not my problem, just reviewing
well i found it pathetic so not like the rest of the past papers i have done. well thank god its over and done with. i didnt even have time to finsh multis were mostly a guess wennt completely blank for it. man compare 2009 and 2010 such a big difference and so not fair
haha it was rather long! I usually got VCAA past exams done with about 30 to 40 minutes left to go over the exam and pick up on mistakes, but in todays exam i finished but it was a rushed job! and i didnt get to look back over my answers oh well ith will be like last years chemistry where they scale the marks
I thought the exam was pretty long and the short answer part was rather difficult. The first question appeared on one of the earlier VCAA exams I think, or something very similar. But the questions towards the end were kinda hard. I dunno if that’s me not thinking straight because of time management or if it was truly difficult. Does anyone know where the answers are published on the web?
Man that one was really hard.
The multiple choice question were horrible because each one required a lot of detailed knowledge. Many of the people in my class barely finished.
So, now I’m totally disheartened by the whole process. I don’t know about the crab question, and the rubella and measles questions could go either way. Know I did crap on the respiration question worth 3 marks.
However, killed the question on mice and experiment.
When can we read VCAA’s answers?
biology exam. It wasn’t particularly hard but it was long….too long. I barely managed to finish it. Some of the multiple choice were difficult and there was just too much information to read. Hopefully I have gotten the short answer questions correct. Honestly if you compare this exam to the 2009 exam, you will notice that the exam was longer and harder than last year’s hopefully it will get scaled up a little.. Cheers
It was pretty hard. I think i couldve done better with more time….
just wondering how people drew the graph of the antibody levels?
and the last two questions in the multiple choice section :S
It wasn’t too bad.
The multiple choice were harder than previous years, and were a bit more vague as well.
The short answers were good and they focused on;
- hormones and negative feedback system
- designing an experiment
- photosynthesis and cellular respiration
- specific immunity
- organelles, jobs of organelles
- DNA/amino acid sequences, enzymes, change in amino acid sequences, drugs
- macrophages, rational drug design, questions you’d ask a doctor if you were put on a trial drug
- immunity, responses to measles (i think) and allergies.
I think that was the general order of questions in the short answer.
It was a bigger exam than the past exams as well.
It was good though, but I do think the mc were harder this year
the multiple chocie was not as straight forward as previous years, even when it came down to process of elimination it was quite difficult to determine the answer, and i agree it was abit too long, i had to rush for the final parts of my exam, but im hoping that i would do well
I found the exam reasonably difficult given the time limit and the amount of reading and understanding required for some of the questions. I reckon personally if I had more time my grades would have definitely gone from somewhere around a B to at least an A+. Hopefully VCAA will scale this exam up and finally stop fluctuating the structure of biology exams so significantly. Furthermore, VCAA should aim to ask direct questions and not questions which are open to interpretation (i.e. What 2 questions will you ask the doctor?).
Overall i found the multiple choice questions hard and the multiple choice confusing and the answers required a lot of explaining which makes it easier to make mistakes. time limit was horrible and when we had to explain the 3 stages of one of the processes did people do aerobic respiration or photosynthesis?
George – im pretty sure you had to relate it to photosynthesis i talked about the Light-Dependant Stage, Light-Independant Stage and Electron Transport Chain
I’m pretty sure it asked you to explain the 3 stages of aerobic respiration after the glucose was made by photosynthesis….3 marks worth, i hope i’m right haha.
That exam was a lot harder than other years, especially that stupid testosterone disease question thingy, it took half my exam to understand!
MC defiantly harder than past years, Was the Crab question alternative A)? what did people write for action when Antibody levels detected?? Retroviral drugs to prevent further reproduction?? no clue. + WHAT WAS THE WASHING POWDER ONE please helps
It thought it wasnt too bad at all… I thought it was cellular resp because it was explain the process that gives the energy, i didnt even think about whether it was one or the other actually;) What did everyone choose for the detergent enzyme MC question??
Poor exam by VCAA..!
personally thought that the short answers we relatively ok, however only did the hypothesis for the experiment so lost two marks for that. What do you think the cut off mark will be?? i think coutnign for mistakes and not finishing i think i may have got about 65-68 /75. The question about the three stages was definetly respiration 1.Glycolysis 2.Krebs 3.Electron Transport. I got 100% on last years when i did it but this year was just out of the blue!
Steph – nobody needs your arrogance here its simple enough to just say I think did well. Although its those who often say it was easy and finished with time to spare that do the worst. So to everyone else, remember a majority of HARD WORKERS would have completely used the time and most may not have finished, but in retrospect we all work against one another and are marks are established through scaling against eachother. Therefore, lets hope we all did poorly!
The exam was difficult compared to the previous years but i think it was alright.
The language was also quite complex, instead of being straightforward (macrophage question)!
i hope the percentage for A+ gets lowered like it was for chemistry last year!
the respiration was worth 3 marks. what did people say for the person who had a disfunctional glucose regulation? the girl’s that went really high or the girls that stayed around the same rate?
what was with the exam. i can normally finish vcaa exams with at leat 30 min to spare. today i was rushed for time. dont worry guys, i go to a school where all the girls do amazingly well and we even found it hard. and what was with the doctor question?…
heyy for multiple choice
the one about the passive movement of substances
in which some answers were
1. multi cellular organism gaining water
and
2. neuron something
what was the answer
@George- yup proin (or whatever it was) must be a protein channel as it was and I quote ‘pipe shaped’. Man who the hell wrote this exam? Stupid crab question!! I just hope it gets scaled up by heaps. I wrote cellular respiration for the 3 mark question because I exactly remember the question asked for the metabolism of the ‘product’ of photosynthesis to obtain energy. Did anyone of you see the 2009 exam? I would have gotten an A+ for that one if those questions were on the exam today.And again multiple choice involved a lot of reading….. NOT FAIR
well what can i say but it is over now, you can’t change it now. i personally don’t think there was enough time, as a lot of reading and re reading need to be done. i was unable to complete the last few questions due to the time limit. compared to previous years of exams i thought it was a lot harder due to all the reading which is time consuming. i tried my best and that is all that matters.
i said that it was the neuron answer as cells enter through the membrane along the concentration gradient which is simple diffusion… the multicellullar organism i thought would need to ‘breathe’ in the water through its gills etc.
i thought the washing powder one was the one that was option a i think? it was the one from 10-30 degrees i think.. not sure though i cant quite remember the question properly.
george- i hope it was! i was so pressed for time at the end i ended up guessing about 5 mc questions and i think i guessed that one for the enzyme question! it is a little comforting in a way to know that others felt the same about the exam. i didn’t speak to anyone after and I was really disappointed because I thought I studied hard yet im pretty sure i was absolutely shredded!!! i couldn’t even read all the short answer questions in the reading time!!
it was hard but my biggest problem was time, the material on this exam was nothing that i focused on in my study, I was feeling quite confident before the exam because i had done really well on all the practises but as soon as I read through the questions in reading time i started panicking It was painfully long and I almost didn’t finish, If there was more time I could have more time to absorb the question and compose the best possible answer but I was so rushed I had to scribble the first thing that came to my head down and move on… it sucks because i have studied so hard for this
Kristina- ur totally right! u r really cocky steph although i didnt finish i think i still did the best as i could so therefore have no regrets about it
@George What did you say for Measels q, obviously AB’s indicate a immune response but what following action should be taken i said give girl antivirals to prevent further replication probably wrong
Thought it was very long, very hard and very challenging. Agree that MC involved a lot more reading which took up a lot of time. Luckily I had a spur of the moment idea to do short answer first which Im so pleased about as I guessed the last couple of MC.
Anyone know what the answer was to the sea slug question that asked how the chloroplasts affect low concentration or something? Did not understand at all.
Also I’m pretty sure we should’ve stated the three stages of respiration – which I didn’t do
Anyone know what we SHOULD’VE written for the doctor questions about coelics disease? Thought they were terrible questions and were too open to interpretation.
2009 exam was MUCH easier!
Overall a good range of questions. Some of them fairly technical. Some of them straight forward if you knew your coursework in detail. There seems to be a tendancy to be heading down the pathway of biochemistry. In fact they should really rename the course biochem. It’s becoming less and less biology as the years pass. ML.
It was sooooo hard! and really long! i studied really well for it too, and the past papers were so much easier. i didnt finish and wasted heaps of time re-reading questions because they were long and kind of difficult to understand what they were asking. a sure fail, terrible day.
Could porin provide structural integrity to the cell membrane like cholesterol – reduce fluidity??? The picture did show beta pleated sheets which are prevalent in high number in structural proteins???
i found this years exam incredibly hard. Multiple choice was not stright forward at all and it was hard to even eliminate. The extended response was alright, as long as you read it all properly. It was really confusing though and you had to read information over and over until you got what they were asking you.
Time was a massive issue. I had done 15 practice exams and each one i finished 20-40 minutes yet this one, i only just finished
What did people say about the chloroplasts in the slug being an advantage? Was it that photosynthesis would produce oxygen and oxygen could be used to produce carbon dioxide….would 60/75 be an A+????????????
but im glad im not the only one who found it hard and long… i walked out of the exam feeling like the stupidest person in the world! good luck for the rest
@ mike. The virus was a RNA virus meaning it is a retrovirus. It could of been treated with a drug that binds with the enzyme nessesary to complete reverse transcription therefore inhibiting the viruses ability to replicate. I also wrote that it could be treated with the adminstration of interferons but im unsure about that being a possible treatment.
I too thought it was extremely long and quite difficult. It was so different compared to past papers and some questions, especially the questions you’d ask your doctor, were totally pointless. My responses weren’t my best because I was so pressed for time.
With the laundry/enzyme one, how were we supposed to know the temperature and pH range of a washing machine????
Isabel, Water has a neutral Ph of around 5, its not acidic or basic and in a washing machine you generally use warm water so i put the one with the ph of around 5 and temperature of 40 degrees i think. I thought it was abit unfair though because it gives people studying chemistry an advantage.
This year’s exam I thought was alright, though I would love to do it right now with a much longer time frame. I was able to finish the exam, thank God but as someone mentioned it was a rushed job especially towards the questions that tripped me up the most. I guess we all just have to wait till the results come out, two more months guys! Hang in there
Btw doesn’t someone usually release the answers anyway? I mean like a day or two after the exam?
Ok, I was doing really well on all the trial exams, but I came out of this exam quite unnerved. The multiple choice were definetly too hard!! And some of the short answers were too basic, and others too convoluted. The questions were a bit ambiguouse… “how does a macrophage destroy” (obviosly not exact wording). Was the question about how does it detect the cell to destroy it, of how it actually does destroy it? i went with how it destroys it…
@ Dave we are both wrong, we didnt read over it probably well at least i didnt i just saw RNA virus and went from there without reading the rest, correct answer was separating child from others b/c measels is highly contagious, everybody would have performed much much better with more time… hopefully it will be scaled a little better though…
Yeh what about the sea slug and the low concentration of chemicals in environment? Was it something about the active transport of the chemicals powered by the respiration?
I agree with you Isabel on the washing machine, Chemistry students definatly have an advantage on these types of questions. But water has a Ph of around 5 as its not acidic or basic and i assume that a washing machine uses warm water of about 40 degrees, but i dont know about that, i dont put a thermometer in my washing machine all that often
well the washing machine would be mainly water which has a ph of around 7. and the temperature of the water would be around 10-30 degrees celcius because any lower it would freeze and higher the water would be too hot..
for the laundry powder question I chose the one with 40 degree and high ph. Because i’m pretty sure a soap and all those things are alkaline. For the measles question, I said I would quarantine the kid. And for the eb-12 question, I said that blocking eb-12 would result in more memory cells???? What questions did you guys ask for drug trial? I thought I would be able to come back to the questions I haven’t been able to solve after I had finished my paper but the supervises said that we had only 5 minutes left and I really started panicking…. Lol@vcaa chemistry tomorrow anyone? Good luck!…….
lol relax kristina, i was on a bit of a hight after exam (very glad it was over :p) and i stumbled on this site, and decided to make a bit of a smart sounding response :p im sorry if i offended at all, i was just mucking aroun and i did in fact find the exam difficult and was pressed for time i used to do the prac ones really quick and have extra time, i barely got this one answered and absolutely no time to check!!
I agree completely with Daniella.. I was also doing quite well on prac exams but walked out of the real thing pretty demoralized, I think there was a lot of sneaky questions in the MC that may have tripped up people who were rushing. Its just like VCAA to turn a biol exam into english comprehension.
To Daniella,
I said that a macrophage destroys the foreign item by phagocytosis (Engulfing the foreign item in a vesicle and then fusing lysosomes containing enzymes with the vesicle destroying the foreign item).
It said in the information that blocking eb-12 would result in a greater amount of memory cells. My interperetation was that in fact, you had to state why that would result in a faster rate of response on subsequent infection. E.g. Because the memory cells ‘Remember’ how to ‘beat’ the infection, and thus, more antibodies are secreted by the plasma cells, and at a faster rate.
For the stupid doctor question I asked if there were any side effects. E.g. drowsiness. And also, how often it would have to be taken.
I agree, this exam took much longer, and the MC especially were much harder than previous year. I was literally writing right up until the lst second of it, but think that i didn’t do too bad. The crab question, washing powder and a couple of others were just ridiculous. But hey, what can you do?
I felt really confident going into it, i knew my stuff and was doing really well with the practice exams. My whole class (theres about 12 of us) walked out in a state of shock. We were so demoralise because of it! Barely anyone finished, and we all agreed the MC was way to difficult, and even some SA were very dodgy. Seeing that everyone else found it complex is a little reassuring, but way to go VCAA for bringing down my sense of confidence in biology. Really looking forward to end-of-year exams now. cough. :/
last years exam felt like a walk in the park compared to this…
mc were too long and random
the doctor question had no real point
i felt like everything i wrote was 100% made up and bulls***
very complex and difficult in comparison to past exams
but congrats if u felt u did well… u probs did
The paper was far to long for the time limit given. When you compare the number of paragraph long and interpretive graph questions between this paper and the 2009 paper, there is no comparison! This paper tried to fit far too much into the time limit and as such was not a true test of what knowlege you had, but how fast you could read and interprete the questions!! Very disapointed with this assessment!!
The multiple chpice section was quite difficult, and the short answer was soo LONG!!! by the time the examiner said 5 minutes left i was still reading the last qestion and just rushed through it! some questions were really easy but some were just so HARD!!
Kids I am a teacher and it was tricky and there were a few traps BUT if you all found it hard so do a lot of the state don’t panic. I wasn’t keen on a lot of the questions but I bet you know more than you think!!! Good luck when the marks come through.
few… i feel so relieved that im not the only one who found it slightly difficult. i agree way too long and very poorly worded questions. MC too many ambiguous answers, was hard to elminate answers…. Short answer- tooo long… and what was with the doctor question??? vcaa this was a really poorly written exam! the unit 4 should be easier
ok to be honest i think it was a fair exam. there wasnt anything on there i hadn’t seen before. i only struggled for time which is a pain. but finished the paper just in time. i actually kinda enjoyed this paper
i hope the A+ cut off mark is lower this year. realistically i think i may have lost 15-20 marks but maube im just being harsh… however i am certain that ive lost 10… so im not tooo sure
I ran out of time!!! Gah, so frustrating. And the most annoying thing was that, when I quickly looked over the questions at the end, I knew I could have answered them. I lost 11 marks just because I didn’t finish. So, unless I got everything I did answer correct, I’m screwed.
Oh well. Bring on genetics!
The first question was gram bacteria… because the question specified “cellular agent” and all the other options weren’t cellular agents apparently. I put virus!!
Overall, this exam was horrific. I went in there, extremely confident and I knew I was going to do well because I had known mostly everything. I then go in there and find that the questions were completely unrelated to what were even concentrating on.. Ambiguous and vague, it had too much reading and there was not enough time AND the exam questions were things WE WOULDN’T EVEN KNOW. What the hell is a piron? I’m sure none of us learned that.. It was like a new study design with the “newly” set out questions.. Or should I say, trick questions.
you weren’t meant to know what a piron was, the whole point of the exam is to provide you with unknown information to which you apply your knowledge to
That’s the problem though, the whole exam was vague and imprecise. You couldn’t have completely known whether a piron was a protein or not.. Or if it caused leakiness in membranes because you were not taught – (Unlike the other exams in which you could apply your knowledge because you knew the answer.)
The exam was full of crap. Questions completely off topic ( maybe a hint of relevance ) and multiple choice were ridiculous, using an elimination process hardly got you anywhere, e.g. laundry question…
Either way, i think i did alright – emphasis on the think – but it was a hard exam and hopefully cut off mark will be relatively low, and we can all be rewarded for VCAA mistakes
I think the exam was alright. didnt just require ROTE learning but testing your understanding and applicatio, eg with the porin. It’s protein, it looks like a tunnel, conclusion?protein channel.
nonetheless i thought the exam was hard
dunmbest q in the wolrd was that one on asking your doctor two questions like how the f was that meant to test ur knowledge anything would have been reasonable. why not ask a real question VCAA. MC was ridiculus compared to past yrs past yrs could get done in fifteen minutes these ones half the time they all seemed right or wrong. first q on multiple choice dumb as.
also wat would anyone have put as a control on the experiment qs? cos i just put 2 groups one hard food one soft….
ok the washing detergent q was stupid. i mean u can set it to cold or warm!!!!!!!!!!!!!! i just guessed cos water has ph of 7 so did 7-9 10-30 degree one. but yeah i could see how ph could change. whole exam was harder then previos years which sucks for us. and doctor qs was biggest waste of two marks in whole exam. u could have seriously asked will it make my hair go red and they have to give you a mark. i just thought it was unfair for us to get the random one. when previus yrs ones were straightforward. not happy. especialy MC
so did i. So i guess i didn’t really have a control? beause you were only provided with two groups of mice.
and agree, doctor question=stupid. but due to it’s ambiguity, hopfully they’ll award most answers a mark.
how was the first MC dumb, it asked which of the non cellular can cause disease, non cellular eliminates all except negative gram strain bacteria which was the correct response
if you did the chem exam youll think bio was shitfully easy. exept atleast the chem one was striaght forward :S the bio exam had to many different interpirtations available
Yeah I think it was pretty hard and alot of people were unprepared. I finished but made up alot of stuff along the way. But I think it’s good that they challenge us and in the long run, most students are better off if it’s a hard exam because it spreads out the marks more and really distinguishes people who put the effort in from people who don’t show up to class.
I personally found the exam to be long, and confusing. Had to re-read stupid questions that didn’t even make any sense. And the multiple choice was extra confusing. Ohhh well though.
pretty sure the question was “cellular” prion was an option, hence it cant be non cellular! bacteria was right! it was one of the onyl mults i was comfortable with!
do you think for the porin question you would get marks if you said it could be a protein channel or a carrier protein to facilitate diffusion and/or active transport? or because one was wrong you wouldnt get the mark? and also with the measles treatment if i said that you should seperate the child from family and friends and also inject more antibodies to aid immunity? or is the second part wrong? Pretty long and hard exams, overall did ok just finished but think i gave a few contradictory answers unfortunately! Thanks
I generally agree with everyone – hard, long and confusing. My bio teacher was so annoyed with some of the questions that he went around asking non-bio people, like English teachers some of the questions, and heaps of them got some right! What’s the point of general knowledge in a bio exam? Isn’t that what the GAT is for? And there was so much graph interpretation! Can’t the VCAA have some sort of fluency between the exams? And some of the answers? How the hell do we know if the kid has a cat or not?
LOL yeah! so true how the hell did we know if he had a cat, yet i said that he could keep his cat very poorly worded questions especially in SA. MCQ were just… And too many general questions that were out of the norm! Bad exam by vcaa, they should be disappointed.
omg i agree it was REALLY complicated.
What about the fertility of the man in that negative feedback mechanism thingo?
And did you pick Emily or Gracie in the glucose concentration question?
I was actually one of the few to finish early by 10 minutes but i also rushed it too much and i needed to go to the toilet the whole time so i think ill get in the mid-60s/75
I thought the exam was harder than other years, the MC was hard and SA was a lot of reading. The exam also had so much reading to do and i thought i wouldnt be able to finsih but i did!
I didnt get time to look back at my answers either…
Emily was the obvious choice IMO but I put Gracie lol. Sort of changed my mind when I was going through the exam at the end but didn’t have enough time to change it.
I found the exam comparatively easy to the trial ones we’ve been doing and think I did alright.
regarding to the time limit, the exam was alright however some questions where plain stupid. Chem students had a real avantage during this exam because of the washing machine question. In my opinion, vcaa shouldnt have made the exam too difficult as biology only cales you up 1. GG man.
This year’s bio exam was reasonable, but long – you needed to read questions quickly. It was somewhat ironic, as in the practice papers which were like 18-22 pages long I used to read fast and answer the questions quickly but in the real exam I went slowly and paced myself – I didn’t anticipate that I was going to run out of time. In the end I finished it with 10 minutes to spare (phew).
As far as I know I haven’t been contradicted in MC so hope for 25/25. As for short answer, there may be a dodgy mark or two that I may lose, but I’m hoping for 70+.
However, that exam was really tricky in some respects – one minute they talk about an enzyme (Hex 6 i think) and they then ask you to talk about the change in shape in a general protein. I NEARLY fell for that trap!
Overall, the VCAA exam setters need to word their questions better!!!
@ Thushan what question did they ask you to talk about the change in the general shape of a protein
@ Isa didnt the question ask what cellular organism can cause disease, because i remember options being virus and prion and some other one they are all non-cellular?
and to add about the washing question OMG i guessed the answer that had the more alkaline pH and it was two that had it i think but washing machines dont get to 120 degrees so obviously the vcaa people were trying to set us up.. i paid close attention to lucky for me i spotted the few!
To all those wondering about the cellular agents, im quite sure the answer is Viruses, becuase it is the only agent capable of entering the cell and taking control. ALthough prions are agents they do not have this ability. Tush, I’ wrote about enzyme changing in the question about the general protein, I’m sure they will understand since the questoin is directly relating to that enzyme. I committed the worst mistake though, in the nucleotide i said ALanine not Adenine, . For the washing question did you guys get ph 10 temp. 40?
the very first MCQ the asnwer is the bacteria choice. It asked for cellular agent!!! the other 3 choices virus, prion and toxin or something. Im sure its the bacteria choice
steph you come across as being slightly arrogant. i am sooooo jealous of the fact you found it so so easy. i did to though so we can be twins:) i also finished multiple choice and short answer in half an hour!!!!!! everyone else found it really really hard but like you i found sinchhh!!!
p.s hope ya study score is 49 coz mines getting scaled up to 55
Back on the cat one, are we all in agreeance that he was allowed to keep his cat? Some of my friend’s think that was the dumb response that VCAA put in as a joke, but if he’s not allergic, why not?
Hi guys I thought the content was pretty reasonable (in hindsight!), my teacher had pretty much covered everything in the exam. But the amount of comprehension and reading that we had to do was insane. Almost every short answer question required alot of thinking to understand it, and there simply wasn’t enough time. In previous years there have been one or two questions consisting of 1 and 2 marks sections where it’s pretty much just definitions. But this year almost everything was applied knowledge. Also, questions like the doctor one were really ambiguous. I didn’t know whether to answer it with the knowledge that a normal patient would have, or with the knowledge I had as a Biology student. Very long and very difficult to understand in the time we had available to us. But congratulations everyone, at least it’s over! Hopefully VCAA will give us an extra easy Unit 4 exam as compensation
For the first MCQ , Bacteria are NOT Agents,
They are organisms that are living, Agents refers to NON living things like viruses or Prions. However it said cellular therefore prions is incorrect since it doesn’t take over cells. Hence Viruses must be the answer,
This is what I have been taught, If anyone has learnt otherwise please correct me.
Virimchi – actually Q1 was talking about an agent that was cellular in nature, not one that infected cells. If it did, then both viruses and bacteria would be right as there exist bacteria that can reside inside cells (eg. Salmonella). So Gram-negative bacteria would have been the answer. But again, that question was very badly worded.
Mike – The question where you had to give the corresponding DNA base sequence to the amino acids was where you had to explain how a change in amino acid sequence changes the shape of a protein and renders it non-functional.
All my confidence has gone down the drain! anyway, I’ve got a question for you guys about that dishwashing or laundry washing questoin,
What answers did you guys put?
*I put ph 10 temp. 40. I’m not too confident the answer may be the ph 7-9 temp 10-30 however, i didn’t think an enzyme could have such a large, range of optimal tempteraturs/ph
The exam was long and rather challenging in the fact that most questions required application of knowledge and careful reading of the stimulus material they supply in the questions. Do not worry though! Every student took the same exam remember, so it was not just challenging for you but for everyone!
M/C was challenging and I know I made at least 1 mistake, but it was good because it will seperate the students who know there stuff from those that don’t. Eg, the question talking about what colour of light is best for the plants in the water tank, the answer is red. I know alot of people would’ve said green, but think! green things are green because they don’t absorb green light!
S/A was good in that it required careful reading of the question and appication of knowledge that you have been taught, for example, the questions talking about these mysterious ‘porins’, they are just protein channels, it said they are tunnel shaped in the question. The question about the measels too required careful reading of the question, it said that it was highly contagious, therfore the best action would be to remove the infected individual from the uninfected.
If anyone has any questions about the exam feel free to ask, I will try to answer as I have access to the answers that our teacher wrote on her copy of the exam and I also feel confident in the answers that I gave.
hey R
it would be amazing if you could scan that exam for everyone
or type up some of the trickier questions
with the experimental question did your teacher put in another control like one group on soft one groap on hard and one group one regular??
i was feeling alright about this exam, though thinking about it i remember quessing half of them The MC was ambiguous and all the SA question were comprehension. in the past exams there was alot more one mark questions which enabled better overall marks. i found alot of questions followed on from eachother and if you were confused for the first part you were stuffed for the rest. im disapointed about the lack of like over half of the unit. i studied heaps for membranes and transport, homostastic functions, which were like a total of 3 marks, and macromolecule structure (which there wasnt one single question about.) this whole exam focused on immunology and drug deisgn. so annoying, i studied so much stuff that didnt even appear in the exam. maybe vcaa should read their own study design before writing the exam. i agree chem students had an advantage in some questions.
anyways goodluck everyone, hopefully we all did slightly bad
“with the experimental question did your teacher put in another control like one group on soft one groap on hard and one group one regular??”
NO, neither did I. The test only required a comparison between the two groups, therfore two groups with different conditions can be used (Not the greatest scientific procedure in the world, but workable)however I don’t think you would lose marks for putting in a control group, as long as you defined what ‘regular’ food is.
“HI, R, What did your teacher say about the question with the laundry powder and enzymes, ? in the MC”
A, as it has the widest range of optimal temperature, and soaps raise the Ph of water.
“just one question R – what was the correct answer to the multiple choice question about allergies?”
He can keep his cat, is that the question you are asking about?
“just one question R – what was the correct answer to the multiple choice question about allergies?”
William can keep his cat, is that the question you are asking about?
“with the experimental question did your teacher put in another control like one group on soft one groap on hard and one group one regular??”
No, as you are only provided with two types of pellets, hard and soft as per the question. So only two groups can be made with a comparison between them being tested.
“HI, R,
What did your teacher say about the question with the laundry powder and enzymes, ? in the MC”
Enzyme J, (option A) as it has the widest optimal temperature range (hot and cold washes) and the ph is high, soaps raise the Ph of water.
I did BLUE for the light question :S i hope that they allow both answers for that one because i didnt know and my teachers didnt know that we had to be able to know which one affects photosynthesis more. :/ Bad question…
any body have solid answer for the laundry question. I put ph 10 opt 40
the other option that appealed to me was the ph 7-9 and tem p10-30 however laundry water is much more alkaline that 7-9 around 10 ish. However with my response, it limits it to a hot wash .
eyy, i picked i think it was B? the temperature of 40, cause 10-30 seemed a bit weird n 10 degress would probs denature the enzyme then 40-42 was weird then the 1xx one was too high , what did you put?
st.hel.gal.3 lol why r u being so arrogrant . leave joe alone
mike – yea i put the bacteria quesiton for the first mc too u sound pro ahaha hope ur right.
that short answer quesiton about the chloroplast or something :S im so dissapointed i couldnt think at all i just had to write some crap down n wrote that it assists with photosynthesis or something ]=
and there was a 1mark quesiton asking for the 3 compounds of DNA, very very dissapointed as i knew this very well n it appeared on i think on the 2009 exam, it was phosphate group, Deoxyribose sugar and base.
and may i ask, what do you guys mean when u say A+ grade lowers or something? i dont understand
well i rekon i would have done very well…if it wasnt for me geting nervouse..(it was the first vcaa exam i eva sat). i got sooo nervouse and couldnt remain focused…:( all the hard wrk went for nothing jst because i couldnt control my emotions… soo not fair.
for the laundry question, i did A the 10-30 one and my teacher reckons its right. but not sure cos it could also be B…. question 1 MC, the answer is D the bacteria choice, as it specifically asked for a cellular agent… virus is wrong and this is confirmed by all my biol teacher
This was my first vcaa exam as well, i wasnt nervous at all, but after the exam i was quite disappointed, because i thought i could/should have done a lot better… but then i realised that A LOT of students struggled with it so it calmed me down.
I think A+ cut off will be anywhere from 55-60, ive heard some ppl say it could go as low as 54 but i think it will be around 57~ that is good for me because thats where i believe i will score
Hello, i reckon this physics exam was hard, and what was with the motion question, guys we are heading towards a very tough day wen the results start coming in. Good luck everyone!
The Unit 3 Biology exam was rather more complicated than expected, after studing past years exam papers from 2006-9 you are only to knowledge in areas of wording, not much really content. The Multiple choice was also very complicated and not always so straight forward; dont meen to repeat peoples words but for example the doctor question was so vegue.
All in all, i believe that the Unit 3 Biology exam this year will be scaled quite well, im expecting from the exam itself and peoples responses something around the figure of 8 (YN) hopefully
Just another point, I hated the ambiguity of the first MC. For some reason I thought that ‘cellular’ meant that it affected cells, so I guessed the question and lost all my confidence <.<
It was only once I left the exam, I realised what they had meant by 'cellular' and how stupid I had been to not realise it.
I actually found the exam hard, ran out of time, writing to much info on earlier short answer questions thought i had done extremely badly, was not at all expecting the mark i got (A+) but it just goes to show that you can walk out of an exam feeling good or bad and end up with the complete opposite. I think Steph and a few others spoke a bit too soon, on a single level the exam could be reviewed as not too dificult, but it is looking for the answers that vcaa want that people need to look at and using correct terminology. Steph i think it is ironic that this happened to you, because saying the exam was easy just makes you look silly now. if it was sooo easy why didnt you get an A+ and my friend got a B+ and then an A+ and ended up with a 37 last year so it just depends.
Might still be in the running for it, depends how ur class did, and where you are ranked within it.
ie, if ur class did well (mostly A’s) and if you are ranked as part of the top of the class, then yes.
Also, your GAT will be considered, but I don’t think it influences biol much.
Hello, I origanally thought that the exam was pretty hard, a lot harder then the ones from previuos years so my hopes weren’t high, but i ended up with an A so i was pretty happy.
heyy dont laugh at me :p i said i was joking on the first post!!! there werent many posts up so i figured i could muck around a bit and i did apologise! awwww will you always hold it against me?! :p
hmm my other one didnt post? or not yet?? anyways i was just saying that i was only joking in my first post (the arrogant one :p) there wasnt many posts up so i thought i could muck around but then yeahh and hey i did apologise! come on, that has to count for something right?? :p
alsoooo… i had a look at the exam because vcaa has released it now, and mannn i think it was the pressure!! i remember i was completely stumped by the multiple choice in the exam but looking now it actually wasnt soo bad at all! hmm who would have thought..
and just a question, how many of you guys happen to be in year 11? i am, so i was a bit curious :p
HAHAHA! Literally did not study as I had a psych exam, and I loathe biology, so I wrote jokes for answers! No, seriously, jokes! Question 5a my answer was “Organelle N provides much needed colour variation in an otherwise bleak diagram. The intense grey hue offers a wonderful contrast to the stark white exterior”. Cannot believe I didn’t fail! The examiners definitely have a sense of humour.
@ Lauren – the examiners still need to mark the exam in accordance with the assessment guide they receive from the Chief Assessor otherwise they don’t get paid!. Jokes or no jokes you won’t get the marks unless you respond accordingly to the question being asked. I’m sure you knew a lot more than you have let on here and good work if you are happy with your result, particularly in a subject you dislike.

I think it was very hard compared to the 2009 and 2010 ones. The exam questions were very unexpected as I studied for the stuff that wasn’t on the exam and didn’t even know about some things on it. There were new words I never knew about like porins or something. Terrible day today.

there was a lot of reading involved and i didn’t get to finish the last question.
i didnt know what the function of a proin was?
the experiment design was straight forward it had come up many times before on past exams, it was expected.
some questions were confusing for example the hormone x and cell y question.
i had to read the questions more than twice to understand them which wasted time.

I thought the exam was pretty long and the short answer part was rather difficult. The first question appeared on one of the earlier VCAA exams I think, or something very similar. But the questions towards the end were kinda hard. I dunno if that’s me not thinking straight because of time management or if it was truly difficult. Does anyone know where the answers are published on the web?

Man that one was really hard.
The multiple choice question were horrible because each one required a lot of detailed knowledge. Many of the people in my class barely finished.
So, now I’m totally disheartened by the whole process. I don’t know about the crab question, and the rubella and measles questions could go either way. Know I did crap on the respiration question worth 3 marks.
However, killed the question on mice and experiment.
When can we read VCAA’s answers?

biology exam. It wasn’t particularly hard but it was long….too long. I barely managed to finish it. Some of the multiple choice were difficult and there was just too much information to read. Hopefully I have gotten the short answer questions correct. Honestly if you compare this exam to the 2009 exam, you will notice that the exam was longer and harder than last year’s hopefully it will get scaled up a little.. Cheers

It wasn’t too bad.
The multiple choice were harder than previous years, and were a bit more vague as well.
The short answers were good and they focused on;
- hormones and negative feedback system
- designing an experiment
- photosynthesis and cellular respiration
- specific immunity
- organelles, jobs of organelles
- DNA/amino acid sequences, enzymes, change in amino acid sequences, drugs
- macrophages, rational drug design, questions you’d ask a doctor if you were put on a trial drug
- immunity, responses to measles (i think) and allergies.
I think that was the general order of questions in the short answer.
It was a bigger exam than the past exams as well.
It was good though, but I do think the mc were harder this year

I found the exam reasonably difficult given the time limit and the amount of reading and understanding required for some of the questions. I reckon personally if I had more time my grades would have definitely gone from somewhere around a B to at least an A+. Hopefully VCAA will scale this exam up and finally stop fluctuating the structure of biology exams so significantly. Furthermore, VCAA should aim to ask direct questions and not questions which are open to interpretation (i.e. What 2 questions will you ask the doctor?).

Overall i found the multiple choice questions hard and the multiple choice confusing and the answers required a lot of explaining which makes it easier to make mistakes. time limit was horrible and when we had to explain the 3 stages of one of the processes did people do aerobic respiration or photosynthesis?

personally thought that the short answers we relatively ok, however only did the hypothesis for the experiment so lost two marks for that. What do you think the cut off mark will be?? i think coutnign for mistakes and not finishing i think i may have got about 65-68 /75. The question about the three stages was definetly respiration 1.Glycolysis 2.Krebs 3.Electron Transport. I got 100% on last years when i did it but this year was just out of the blue!

Steph – nobody needs your arrogance here its simple enough to just say I think did well. Although its those who often say it was easy and finished with time to spare that do the worst. So to everyone else, remember a majority of HARD WORKERS would have completely used the time and most may not have finished, but in retrospect we all work against one another and are marks are established through scaling against eachother. Therefore, lets hope we all did poorly!

I wrote cellular respiration for the 3 mark question because I exactly remember the question asked for the metabolism of the ‘product’ of photosynthesis to obtain energy. Did anyone of you see the 2009 exam? I would have gotten an A+ for that one if those questions were on the exam today.And again multiple choice involved a lot of reading….. NOT FAIR

Overall a good range of questions. Some of them fairly technical. Some of them straight forward if you knew your coursework in detail.

Isabel, Water has a neutral Ph of around 5, its not acidic or basic and in a washing machine you generally use warm water so i put the one with the ph of around 5 and temperature of 40 degrees i think. I thought it was abit unfair though because it gives people studying chemistry an advantage.

I agree with you Isabel on the washing machine, Chemistry students definatly have an advantage on these types of questions.

James | Jun 8, 2010 | Reply
It said in the information that blocking eb-12 would result in a greater amount of memory cells. My interperetation was that in fact, you had to state why that would result in a faster rate of response on subsequent infection. E.g. Because the memory cells ‘Remember’ how to ‘beat’ the infection, and thus, more antibodies are secreted by the plasma cells, and at a faster rate.
For the stupid doctor question I asked if there were any side effects. E.g. drowsiness. And also, how often it would have to be taken.
I agree, this exam took much longer, and the MC especially were much harder than previous year. I was literally writing right up until the lst second of it, but think that i didn’t do too bad. The crab question, washing powder and a couple of others were just ridiculous. But hey, what can you do?

Seeing that everyone else found it complex is a little reassuring, but way to go VCAA for bringing down my sense of confidence in biology. Really looking forward to end-of-year exams now. cough. :/

Steph | Jun 9, 2010 | Reply
The paper was far to long for the time limit given. When you compare the number of paragraph long and interpretive graph questions between this paper and the 2009 paper, there is no comparison! This paper tried to fit far too much into the time limit and as such was not a true test of what knowlege you had, but how fast you could read and interprete the questions!! Very disapointed with this assessment!!

Overall, this exam was horrific. I went in there, extremely confident and I knew I was going to do well because I had known mostly everything. I then go in there and find that the questions were completely unrelated to what were even concentrating on.. Ambiguous and vague, it had too much reading and there was not enough time AND the exam questions were things WE WOULDN’T EVEN KNOW. What the hell is a piron? I’m sure none of us learned that.. It was like a new study design with the “newly” set out questions.. Or should I say, trick questions.

That’s the problem though, the whole exam was vague and imprecise. You couldn’t have completely known whether a piron was a protein or not.. Or if it caused leakiness in membranes because you were not taught – (Unlike the other exams in which you could apply your knowledge because you knew the answer.)

The exam was full of crap. Questions completely off topic ( maybe a hint of relevance ) and multiple choice were ridiculous, using an elimination process hardly got you anywhere, e.g. laundry question…
Either way, i think i did alright – emphasis on the think – but it was a hard exam and hopefully cut off mark will be relatively low, and we can all be rewarded for VCAA mistakes

I generally agree with everyone – hard, long and confusing. My bio teacher was so annoyed with some of the questions that he went around asking non-bio people, like English teachers some of the questions, and heaps of them got some right! What’s the point of general knowledge in a bio exam? Isn’t that what the GAT is for? And there was so much graph interpretation! Can’t the VCAA have some sort of fluency between the exams? And some of the answers? How the hell do we know if the kid has a cat or not?

Thushan | Jun 10, 2010 | Reply
This year’s bio exam was reasonable, but long – you needed to read questions quickly. It was somewhat ironic, as in the practice papers which were like 18-22 pages long I used to read fast and answer the questions quickly but in the real exam I went slowly and paced myself – I didn’t anticipate that I was going to run out of time. In the end I finished it with 10 minutes to spare (phew).
As far as I know I haven’t been contradicted in MC so hope for 25/25. As for short answer, there may be a dodgy mark or two that I may lose, but I’m hoping for 70+.
However, that exam was really tricky in some respects – one minute they talk about an enzyme (Hex 6 i think) and they then ask you to talk about the change in shape in a general protein. I NEARLY fell for that trap!
Overall, the VCAA exam setters need to word their questions better!!!
mike | Jun 10, 2010 | Reply
@ Thushan what question did they ask you to talk about the change in the general shape of a protein
@ Isa didnt the question ask what cellular organism can cause disease, because i remember options being virus and prion and some other one they are all non-cellular?

To all those wondering about the cellular agents, im quite sure the answer is Viruses, becuase it is the only agent capable of entering the cell and taking control. ALthough prions are agents they do not have this ability. Tush, I’ wrote about enzyme changing in the question about the general protein, I’m sure they will understand since the questoin is directly relating to that enzyme. I committed the worst mistake though, in the nucleotide i said ALanine not Adenine, . For the washing question did you guys get ph 10 temp. 40?

Hi guys
I thought the content was pretty reasonable (in hindsight!), my teacher had pretty much covered everything in the exam. But the amount of comprehension and reading that we had to do was insane. Almost every short answer question required alot of thinking to understand it, and there simply wasn’t enough time. In previous years there have been one or two questions consisting of 1 and 2 marks sections where it’s pretty much just definitions. But this year almost everything was applied knowledge. Also, questions like the doctor one were really ambiguous. I didn’t know whether to answer it with the knowledge that a normal patient would have, or with the knowledge I had as a Biology student. Very long and very difficult to understand in the time we had available to us. But congratulations everyone, at least it’s over! Hopefully VCAA will give us an extra easy Unit 4 exam as compensation

Virimchi | Jun 11, 2010 | Reply
For the first MCQ , Bacteria are NOT Agents,
They are organisms that are living, Agents refers to NON living things like viruses or Prions. However it said cellular therefore prions is incorrect since it doesn’t take over cells. Hence Viruses must be the answer,
This is what I have been taught, If anyone has learnt otherwise please correct me.
Thushan | Jun 11, 2010 | Reply
Virimchi – actually Q1 was talking about an agent that was cellular in nature, not one that infected cells. If it did, then both viruses and bacteria would be right as there exist bacteria that can reside inside cells (eg. Salmonella). So Gram-negative bacteria would have been the answer. But again, that question was very badly worded.
Mike – The question where you had to give the corresponding DNA base sequence to the amino acids was where you had to explain how a change in amino acid sequence changes the shape of a protein and renders it non-functional.
Virimchi | Jun 11, 2010 | Reply

The exam was long and rather challenging in the fact that most questions required application of knowledge and careful reading of the stimulus material they supply in the questions. Do not worry though! Every student took the same exam remember, so it was not just challenging for you but for everyone!
M/C was challenging and I know I made at least 1 mistake, but it was good because it will seperate the students who know there stuff from those that don’t. Eg, the question talking about what colour of light is best for the plants in the water tank, the answer is red. I know alot of people would’ve said green, but think! green things are green because they don’t absorb green light!
S/A was good in that it required careful reading of the question and appication of knowledge that you have been taught, for example, the questions talking about these mysterious ‘porins’, they are just protein channels, it said they are tunnel shaped in the question. The question about the measels too required careful reading of the question, it said that it was highly contagious, therfore the best action would be to remove the infected individual from the uninfected.
If anyone has any questions about the exam feel free to ask, I will try to answer as I have access to the answers that our teacher wrote on her copy of the exam and I also feel confident in the answers that I gave.

“with the experimental question did your teacher put in another control like one group on soft one groap on hard and one group one regular??”
NO, neither did I. The test only required a comparison between the two groups, therfore two groups with different conditions can be used (Not the greatest scientific procedure in the world, but workable)however I don’t think you would lose marks for putting in a control group, as long as you defined what ‘regular’ food is.
“HI, R, What did your teacher say about the question with the laundry powder and enzymes, ? in the MC”
A, as it has the widest range of optimal temperature, and soaps raise the Ph of water.

No, as you are only provided with two types of pellets, hard and soft as per the question. So only two groups can be made with a comparison between them being tested.
“HI, R,

The Unit 3 Biology exam was rather more complicated than expected, after studing past years exam papers from 2006-9 you are only to knowledge in areas of wording, not much really content. The Multiple choice was also very complicated and not always so straight forward; dont meen to repeat peoples words but for example the doctor question was so vegue.
All in all, i believe that the Unit 3 Biology exam this year will be scaled quite well, im expecting from the exam itself and peoples responses something around the figure of 8 (YN) hopefully

Does anyonw know the cutoff point for the A+ mark? And what is it usually?
(p.s was there anyone else at Melb uni on monday the 2nd for the fly thing?)

A+ ;D
I reckon I just made it, as I went home after the exam and found atleast 12 marks I had wrong.

Just another point, I hated the ambiguity of the first MC. For some reason I thought that ‘cellular’ meant that it affected cells, so I guessed the question and lost all my confidence <.<
It was only once I left the exam, I realised what they had meant by 'cellular' and how stupid I had been to not realise it.

hey remember me the arrogant one?? :p
i got B+
i was really hoping for a 40 in biology, does anyone have any idea of the chances of that still being possible?
thanks a million!

What score do you think is required out of 75 in this exam to be in the running for a 50 study score, given that this exam was relatively difficult?

omg steph im laughing so hard right now seriously, your not so arrogant now huh?? depending on whether high or low b+ can still get 40
ash | Aug 8, 2010 | Reply
so even with a B+ study score of 40 is still possible? :\

I actually found the exam hard, ran out of time, writing to much info on earlier short answer questions thought i had done extremely badly, was not at all expecting the mark i got (A+) but it just goes to show that you can walk out of an exam feeling good or bad and end up with the complete opposite. I think Steph and a few others spoke a bit too soon, on a single level the exam could be reviewed as not too dificult, but it is looking for the answers that vcaa want that people need to look at and using correct terminology. Steph i think it is ironic that this happened to you, because saying the exam was easy just makes you look silly now. if it was sooo easy why didnt you get an A+ and my friend got a B+ and then an A+ and ended up with a 37 last year so it just depends.

Might still be in the running for it, depends how ur class did, and where you are ranked within it.
ie, if ur class did well (mostly A’s) and if you are ranked as part of the top of the class, then yes.
Also, your GAT will be considered, but I don’t think it influences biol much.

Hello, I origanally thought that the exam was pretty hard, a lot harder then the ones from previuos years so my hopes weren’t high, but i ended up with an A so i was pretty happy.

HAHAHA! Literally did not study as I had a psych exam, and I loathe biology, so I wrote jokes for answers! No, seriously, jokes! Question 5a my answer was “Organelle N provides much needed colour variation in an otherwise bleak diagram. The intense grey hue offers a wonderful contrast to the stark white exterior”. Cannot believe I didn’t fail! The examiners definitely have a sense of humour.

@ Lauren – the examiners still need to mark the exam in accordance with the assessment guide they receive from the Chief Assessor otherwise they don’t get paid!. Jokes or no jokes you won’t get the marks unless you respond accordingly to the question being asked. I’m sure you knew a lot more than you have let on here and good work if you are happy with your result, particularly in a subject you dislike.

Sorry for the double-post, but I think my question might have been overlooked…
What score do you think is required out of 75 in this exam to be in the running for a 50 study score, given that this exam was relatively difficult?
