38 should defs be C not D imo. (hominoids includes apes)
38/40 so happy haha..
are we thinking 38/40 is a good score on MC because I'm pretty sure I got 38-40/40 (got to check all my MC's) :)
i only got 37, didnt read 11 properly and got 21,22 wrong as well
Happy to be proven wrong (well not really but I'll cop it).
can someone go over 24 i am still in denial.. (I said C) and also 39 (I said D)

Can someone go over multiple choice q22? Not all the cells after image 10 are haploid because only one division has occurred - only after the second division they would be haploid??
I got 33/40 :( Is that good or bad?
Could've got more right but I overthought and rubbed out 3 correct answers UGH
All down to short answer..
what did you guys write about the translocated chromosome (the consequence on the genetic makeup of daughter cells)?Have a read of the solutions
I said that the result of meiosis I (as crossing over happens during meiosis I) will result in non-identical sister chromatids in the daughters cells, something like this. Is this correct? I am so unconfident about this one :(
For the snyapse question, I had the same step 1 but step 2 i said that the neurotransmitter vesicles undergo exocytosis and are released into the synaptic cleft, then step 3 was they diffuse down to post synaptic membrane from high to low concentration, because the question said 'transferred across a synapse'. Would this still get me full marks?
For 7c, your solution states "Pituitary gland has different GC receptor to liver cells thus a different GCR-complex isHmmmm I could be wrong, but in writing that solution I had question 3c from the 2013 VCAA paper in mind which was very similar. I think that if both cells had the same receptor then the same signal transduction pathway would be activated leading to the same response since there are no other molecules (besides DNA) involved. Do you have a different explanation?
formed."
But i'm pretty sure that the receptors are the same. It's just that they have different signal transduction pathways within a cell that leads to different cellular responses.
You may loss a mark for not explicitly stating that the neurotransmitters bind to receptors at the post-synaptic membrane.That's nothing; I said mitosis instead of meiosis in the crossing over question *facepalm*
i'm cringing so hard because for the light-dependent inputs, i said light!! I wasn't aware it said molecules
I did the same, however I had 'photon' in brackets. There molecules aren't they haha?

Comparative Anatomy? If you said comparative morphology is that -1?Both are correct
for the innate cell found in the lymph nodes, could i have said natural killer cells?As far as I know, there are no NK cells in the lymph nodes. Dendritic cells or macrophages would have been acceptable answers though

i actually cant believe this, i lost 10 marks minimum this just stings..
How do you get an account tho?

Am I the only one that the 'download file' button is not showing up for the short answer solutions? :'(
It should say 'Link to share this file with anyone' - copy and paste that link into a new tab, and you should get your download there :)

Answer is correct. Just wanted to note that this is a really disappointing question, I daresay most would not have been taught this. The valves allow for unidirectional flow of lymph.
Hmmmm I could be wrong, but in writing that solution I had question 3c from the 2013 VCAA paper in mind which was very similar. I think that if both cells had the same receptor then the same signal transduction pathway would be activated leading to the same response since there are no other molecules (besides DNA) involved. Do you have a different explanation?
If you read the first part of this question again, it explains that the gene activated is the same, so would the best answer be to describe how alternative exon splicing can produce different proteins from the same gene?
When you think it's not pointing to the valve but the vessel and you give the function of the lymph vessel :-\ wow just wow, I really messed up this exam.
To be honest from what I have seen on the exam for this question (briefly looked at this question), alternative splicing is probably the best answer. It is the way to account for the fact that the same genetic sequence can yield different proteins (alternative splicing of exons = different AA = different tertiary structures & 3D protein conformations). So yup :-)
Guys I see you're all down so I'm just going to post this!thanks, I really needed that
Remember that when VCAA sets a difficult exam, it often means that if YOU guys who are extremely bright and well-equipped with Biology knowledge will be rewarded because the bell-curve will be in your favour. I personally know someone who walked out of our Biology exam and was adamant he was going to get nothing above 36-37, and ended up surprising himself and getting a 50. Why? Because in Biology, you just never know. So while some of you may be gutted having checked the answers, I strongly recommend you realise it's not over. You never know, you may be pleasantly surprised when results come out!
thanks, I really needed that
personally how did you feel coming out of your exam and having looked at both 2013 & 2015 exams is it safe to say cut-offs will be lower for 2015.
When I came out of my exam, I was happy ( I sat it in 2013 and you can probably agree it is significantly easier imo than 2014 and 2015). But I still had doubts - my answers may have been a) completely off or b) not been to the liking of my assessors of what not. Biology you really never know, and I was ready to get a SS in my 30s too because you never know.just for reference 2014 was really easy A+ cut-off was 96/110
I 100% think cut-off will be lower than 2013, 2015 either will be a little bit lower or equal to 2014, but I reckon A+ cut off 87-92/110. That's just my prediction though!
& another thing; don't let a SS dictate your experience of a subject. I loved English, and still believe it was my strongest subject and I was incredibly disappointed when I got 42 for all the work I put in. However, my passion for English remains and wont be overshadowed by my SS. Neither should Bio if God-forbid you don't do as well as expected.That was my whole experience for VCE actually; my ATAR was lower than I deserved and I was disappointed. But it's not going to dictate my ability or future :) Good luck guys!
just for reference 2014 was really easy A+ cut-off was 96/110
A+-cut-off predictions have been around 90 so that's a little bit of hope, thanks
Do you guys know anyone who was actually genuinely happy (and aiming for a high SS) coming out of that exam?
I have two strong students who admitted that there were several questions that were tricky. One of my students who LOVED evolution hated the amount of evolution covered in the exam, so not that I have heard of, no!2014 was pretty much if you've done all the past vcaa exams you'd do well.
And wow! I didn't check grade distributions for last year - I totally reckon 2013 was a better exam than 2014 though. 2013 really reflected a good Biology student's knowledge on the exam. Many people who I know that sat 2014 felt ripped off.
2014 was pretty much if you've done all the past vcaa exams you'd do well.
I know that you got 101/110 for your bio exam, did you check solutions and estimate an exam score?

I only checked multiple choice, and knew I'd scored 40/40 and stopped there. I didn't want to check short answer because I also had further maths exams and I didn't want to know if I had made mistakes on short answer for Bio because it would cloud my ability to study for further. I'm not one who likes to check answers lol!
so yacoubb you got 101/110 and were you rank 1 for the 47? the cut off was 93/110, so it doesnt work like if you get half the cut off, you get 45? im so desperate right now i should just study for spesh ...
With that question on recombinant gametes where you had to fill in the box. I only did BR br and left the two other boxes blank..would they accept that?
I know a friend who got 45 in Bio my year and scored 97 or 98 (I forget exactly). So I guess that's around the half-way mark. I was actually annoyed because when I got back my results (statement of study score) I realised that I lost marks from one assessor more than the other. Like one assessor I think took off like 4 marks, and the other took off like 14 marks. It just goes to show - you don't kno and it depends a lot on who is marking your work. The crazy Bio lady who wants everyone to fail because she didn't get above 45 in Bio, or the relaxed guy correcting exams on his balcony in CBD. Luck.would it go to a 3rd assessor if that was the case.
I think you'd get part marks - given that 4 gametes are produced you'd had to have just shown 4 gametes (2 just repeated). I know it's such a stupid way of asking the question.
would it go to a 3rd assessor if that was the case.
Also I'm pretty sure that bio examiners mark in sets of questions now e.g they go through 50 question 1's
thanks for that yacoubb.
that question was 2 marks, and there was 8 possible genotypes. do you think they would allocate only 1 mark if you got 4 of the 8 correct? or does it again depend on assessor?
Thanks Yacoubb and bangali_lok; I really appreciate your consoling words. :) It's difficult, for me, not to stress and fret over my answers on the exam but you guys have made me feel a bit better about everything.
I know a friend who got 45 in Bio my year and scored 97 or 98 (I forget exactly).hopefully it's even lower this year
hopefully it's even lower this year

Really sure it will be!
hey, how do check out the short answer solutions? all that comes up is a link and when i click nothing comes up.The link was broken for some reason. It's fixed now.
