A2 Biology OCR June 2015 Revision Thread

What do you reckon grade boundaries will be surely one of the lowest it's been in a long time?

On one hand, those who didn't learn the content well would have been ok compared to them doing last years paper but people who did might not have done as well as a paper that had so many recall questions. So I think it brings people up but lowers the really studious people at around 50-80 and no higher. I think the grade boundaries will be marginally higher as a result

for the question about why X^2 value was not due to chance, i mentioned that it was due to no random mating and not a large population, is this completely wrong?

I completely agree I spent so long doing past Q's and revising.. and I swear it only gained me an extra 12 marks than what i would have gotten anyway...but than i dropped probably 10/15 marks extra due to how stuff was phrased its riduculous.. half the knowledge was as and some of it was unit 4 based -.-
The worst thing is i dropped like 12 marks beause of stuff i genuinely didn't know which is fine but some of the questions like about thrombosis and the treatment of it and how it is usaully the casual treatment and it said explain why genuinely confused me (I didn't know if it was asking why there was a range of treatments for different stuff or why the thrombosis was treated for strokes as the standard) not because I didn't have the knowledge but because i swear the questions this year some of which were tooo ambigous or too many suggest questions which leads to the idea that there should be a range of answers but there won't be even thouh its a suggest question.
I honestly felt there wasn't enough actaul a2 f215 knowledge and the questions were not specific.. Too many suggest questions which makes me believe the suggest questions won't have a wide range of answers as they have had previously

I need 40 ums from this to get a C overall, do you think I'd get that with 33/100?

Should be 50-60 so yeah you're fine, probably more like 60

Surely the answers to the first question were meiosis 1 and meiosis 2, as meiosis occurs in the reproductive organs and the question asked about the testes? Also, is there an unofficial mark scheme yet?

How is the automated DNA separated?

Was it electrophoresis?

What question was was that?!

It was a 4 marker asking how dna fragments were arranged into size by the machine. stumped me as all i could think of was electrophoresis but then i didn't think that'd be done by a machine so i dunno

I hope so me going to uni depends on this.

It didn't help that the invilator kept asking me if I was OK every 10 min + exam officer is a bitch and hates everyone and wouldn't allow me to apply for special consideration despite teachers saying I should be allowed.

40 ums would be like 20 marks?? Lol are you okay
