did that domain of F^-1(x) incorrect one of my friends quoted that it was 0<x<=2.5 whereas I wrote it as x<=2.5

n = 25 for thr the arithmatic progression
coefficient of x^2 was 60 in first part and 40 in second.
just did a 1 mark error in p1. hoping to get 74, Insha Allah

In Sha Allah.
Pray that the rest of us get A's too.

Nicee wat do u expect the gt to be ??

It's going to be in the 50's.
I had a long chat with my big brother(who gave his AS maths paper last year in M/J 2012)
He said his paper was fairly difficult too.
the gt for his paper was 58/60.
I've attempted that paper, and tbh, didn't find it as tricky as our's.

insha ALLAH.
I really did messed up that coefficient of x^2 question part (ii)
corrected it just at the last half a minute or even less, and in the process of hurrying did a lot of scribbling, I hope the examiner understands the answer 40. Itmite lead to a 1 mark deduction as well

Ah, so I wasn't the only who got it wrong at first. :D
I don't think scribbling results in a lose of marks, I remember reading an examiner report saying "Some candidates got a hint of what the answer to part (i) would be thanks to part (ii) and so returned to rectify their incorrect answers."
Usually they ask us to find the coefficients required for the second part in part 1.
But this time we had to do a bit more :D

Alright guys, since 24 hours are up, these are some of the answers I remember of mine (Paper 12)
2(i) co-efficent of x^2 was either 64 or 60 (cant remember exactly)
(ii) coefficent was 124
3 m= -3 and P = (2,8)
4 (ii) Perimeter=20.4
(iii) 7.96 Area of shaded region
5 (i) [a^2 +b^2] The constant was being proved to be 10
(ii) 116.6 and 296.6
7 R(7,15)
10 (i) 25 terms
(ii) -21 and 63
11 (i) y=-0.5x+1
(ii) 7/6

Note=I am not saying any of these answers are correct but this is what I wrote. Please tell me which I got correct or wrong.

your anser no. 2 part (ii) is incorrect, and the trig. angles are incorrect I guess
the angles were 98.1 and 278.1 in my case

I did the same thing as you :p
I don't think zero is a domain. Cuz range was >=1, it would reach close to zero but not zero as such. :)
