yeh the 480 doesnt change... but this paper out of 150 UMS, its 120 UMS for an A... if the boundaries are lower this year, it means you need fewer marks to get the 120UMS (or whatever you need). In january it was 66 marks/100 to get the 120UMS... theres hope yet for us all
It was 60 http://www.ocr.org.uk/download/admin...l_raw_mark.pdf

so retaking... oh wait, i can't. I mean seriously OCR if your gonna f*** up a paper like this at least do it when we can have another go at trying to understand what you want us to write rather then when our uni's depend on the grade.

I got 0.83 and 0.17, but thinking about it now, i got 0.17 by finding the square root of 293 (or whatever the size of the red type was) didnt we need to find out the percentage of red out of the WHOLE population, e.g. 50 + 293 = 343, 293/343 = q squared? Not sure, lets keep our fingers crossed!
Yeah that makes sense but I though it was 50/294 not 50 black and 294 red! Must of misread the question

So why was this paper on Ecology and Environment? The hardest topics which most of us hate....

Does this mean F214 will have the hardest topics and ones we hate? Will we see a repeat of the Jan10 paper?

Not a good start to two weeks of exams. Gotta try to get AAA in my other three subjects and see if UCL will negociate
Unfortunately, I only do three subjects. I might have to just try and do well in the F214, but judging by this crappy one -.- i doubt F214s gonna be any better

Mate, dont worry about it, I cant quite remember myself, it seemed right at the time, but doesn't it always! and the frequency still makes sense, but maybe we've mixed the 2 up, wasn't Q Red, and Red was the majority of the population and therefore couldnt be 0.17? Trigger any memory?

Wasn't it you had to double the population first to give the number of alleles and then because there were 296 red that was 592 red alleles over the 692, which then gave 0.86 so the red was 0.86 and black was 0.14??

I hope OCR are proud of them selves. All those trees chopped down to create a pile of **** exam like that. Hardly ecological is it

Red = bb
296 = bb

296/346 = 0.855
q^2 = 0.855
q = 0.92

1-q = p
p = 0.08

q = 0.92
p = 0.08

Looking over the exam, I'm feeling pretty confident. At least 78/100.

my working (extracted from calculator)

296 + 50= 346

296/346=0.855

(0.855)*0.5=0.9249

1-0.9249= 0.075

Final answers- p=0.08, q=0.92
I think I was inconsistent with decimal places but I just carried through with my calculator value so should be no rounding errors
final answer had to be to two decimal places
Yeah, I rounded it to 0.86 (don't ask why) and then I ended up with 0.93 and 0.07, which is wrong lol... I think my working out may be too scruffy as well, so those clown OCR biologists would probably just give a fat 0 at a glance.

for the evaluation of his conclusion i said that his statement was true cause it does show an increase at high altitudes possibly cause the black are better adapted to survive than reds but i said the conclusion was wrong as at high altitudes it doesnt cause them to survive it helps them too would i get any marks for saying that lol?
