# OCR (non mei) C4 Friday 24th June 2016 watch

1. I found that paper today notoriously hard, anyone agree?
2. (Original post by Dom1997)
You'll lose 0/1 on what was a difficult question so I wouldn't worry.

isnt it e^(ln(1/144)+2)=y
3. 61 for A*?

isnt it e^(ln(1/144)+2)=y
2=2lne=lne^2 so ln(1/144)+2=ln(e^2/144)
6. hopefully 51 for an A? this was very hard like june 2013 and 14??

Can you make it viewable without access?
8. why do you have to request access just do it like the C3 one
9. Anyone remember what question 2 was?

sorry here

Last year was way easier
With due respect, I am saying this without all the added exam stress.

Have a look at what people said last year about their c4 exam, every year people always say "This is the hardest exam ever".

It's not! Have a look at June 14 c4, the questions there were much more challenging then what we had today.

I did the same, I just assumed i flopped the whole Q but does that simplify to the right answer?
I'm pretty sure it does I haven't tried though because I'm not feeling doing more a level maths after I'm done ahah. Without the simplifying bit the differential equation was decent and getting it in the right form was the really tough bit so I think i might have got it right? I'm just not sure how many marks there would be for simplifying it

14. Agree with every single one of those solutions.
15. Q5 asked for coordinates not position vector
16. I was an idiot in the last question and left it as (9/1296)e^2

Will I lose a mark?
17. How many marks was the whole of question 9 worth and what were the breakdowns please?

What did you put?

It was very stupid of me to put it like that but I do think it's in the right form.they asked for Ae^x. A=1 and e=(ln(e^2)/144)
No A=e^ln(1/144)
A= 1/144
So is (1/144)e^2

I think

unlucky dude the last one is y=e^ln(1/144)+2
