# OCR C2 exam Wed 25th May Watch

1. (Original post by hunihuni)
I reckon the difficulty was similar to last year's paper which was 64/72 for an A
2. Anyone else get last question x =1/3a pi and x = 4/3a pi ? Thought it seemed too simple for four marks
3. (Original post by Christie_xx)
Same to both if you mean k=91
+/- root 3 for the value of k for the coefficient one too?

Yeah I think I got that, it was easier than the 3 makrer before IMO

The last question might have been a tad easier than last year's but I would agree about 64 ort 65 /72
6. No, A is 3/5 as the 5/3AX gives values

i.e Sine(5/3X36) = Sine(60)

So your A is 5/3 for application however the scale factor is 3/5

A=3/5 whcih when applied goes to 5/3
K- root3/2

What? You're confusing the C1 grade boundaries and C2. Last year was 57 for an A.

Oh. Sorry, maybe 58 or so then
15. What did people get for N with the arithmetic and geometric series?

translation 2 units in x axis before?

Ahh I thought I'd got this one wrong 😭
