1. Can anyone remember the marks for each question?
I remember the last one was 9, but if anyone could tell me that would be great xox

My reaction to the sad news that i did it wrong:
Haha, yeah I think I did it pretty differently to most people so don't take my working as the only way by any means but I think my answers match up with the ones others have discussed so it's one way of doing it.
3. Does anyone know how many marks 1a and 1b were worth individually?

Anyone know what an A* is usually?
usually 68/75
5. Was anyone able to prove that the root of g(x) was α=1.473 to 3dp?
6. Defo harder than last years paper so u reckon itll be less than 59 for an A?

My reaction to the sad news that i did it wrong:
Yeah, as the other poster said you could also do it using polynomial division and then simplification of the fraction.

no chance of 64 for an a*, its never been that low
Mate, it was 57 in '13.
9. Anyone have a photocopy of the paper and an unofficial mark scheme they can send to me considering Arsey isn't doing them anymore?
10. (Original post by celecia01)
2 marks
Cheers.
11. (Original post by Pablo Picasso)
83-84
Really ? So A* would be like 71/75 ish

For question 4a (the one with the modulus graph), for y = 0, I wrote x = 0.5ln(6.25), not noticing that 6.25 can be rooted to 2.5. How many marks was that? Will I get full marks for that one, or do those questions typically require a simplified answer?

Also, how did people find that compared to the June 2015 and June 2013 paper? Those are the ones I didn't do for prep, so I can't judge
Definitely easier than the 2015 paper
13. I split into 2Cos2x/Sin2x and used to Cos^2x - Sin^2x for cos double angle, along with dividing and simplifying the Sin double angle. Have a try? It should work.

14. the long division way

Yeah you do use the equation 4e2x - 25 - 2x - 43. That would give you an a positve and negative answer. Around -0.08 and 0.08 i think it was.

Anyone have an idea of what the boundary for an A* will be like?
(Original post by victoria98)

69-70

100% doubt that, it'll be similar to last year.
