1. OCR C3 exam 14th June 2012
How did people find the exam???
2. Re: OCR C3 exam 14th June 2012
struggled on a few qs like the ksin(theta) thing didnt have a clue so thought I'll make them into simultaneous equations as 2 variables kinda thing :/ I think fairly straight forward paper over all but some of my answers seemed wrong but method marks hopefully. CORE 4
3. Re: OCR C3 exam 14th June 2012
I made so many stupid mistakes. In the Rates of change question my differentiation was wrong which just threw the whole question off. Also, in the last question I thought it was a revolution round the x axis when the question said y so I didn't do that either.

If you got part 9(ii) marginally wrong, are you likely to get follow through marks for part 9(iii)? If so how many?
5. Re: OCR C3 exam 14th June 2012
can someone put up the question paper if they have it?
6. Re: OCR C3 exam 14th June 2012
What did people get for the question where you had to find K and c? I ended up getting something like 0.0295 and 38 which im guessing is completely wrong!!

I thought it was an alright paper, found it all pretty straight forward about from the c and k one, i attempted it and im guessing you get simulataneous inequalities? i have no idea but i hope i get 1 or 2 marks for that. the rest was quite easy
11. Re: OCR C3 exam 14th June 2012
i got c=3 and k=8
12. Re: OCR C3 exam 14th June 2012

and did people get n=361 for 2ii
