How many marks was q6)c and q9 a,b,c,d?(Original post by TrueDAN)
Damn you have a good memory. That's sick!
For 9C i got £1050 but I may have messed up on it.
For 11 C and D I got the Y to equal 1/2 and D I got 17x2y + 35 =0 so again I may have messed up.
For 10c : I am pretty sure that it is 162/3 units^2 and not 76 via splitting it into a trapezium and triangle.
I agree with the simultaneous equations  I definitely got answers like that.
Thanks for remembering Q11 A I agree with that and they for the rest I got the same!
I got 17x2y+35 too
and 162/3

That was a tough paper no question. here are some of the answers I got, that my memory can recall. Feel free to share any you remember before the unofficial one is released I feel like I have done worse than expected
Q1. Typical integration question  should be fine as long as you remember the +C
Q2. 3^6x + 2 : I nearly messed up on that one yikes!!
Q3. 5root2  3root2 leaving 2root2
I then got 3root6  you ended up with 24root6 over 8
Q4.
Q5. Not a fan of this one at all. 5K and a quadratic  my memory is slacking!!
The one marker was 500  you got 5 each time  I guessed this one and got it wrong.
The hell of a quadrilateral I got 326/6 which you could simplify to 163/3 units^2. I split it into a triangle and trapezium. The fact that R was 44/3,0 is just cruel.
You got this from the equation 3x  4y 44 = 0 or again something similar to that. Y = 0 at point R so 3x=44 therefore X = 44/3
The value of K was also awful  I got 41/8 via equating the gradient function to the gradient of the line being 17/2. Again, nasty nasty numbers.
Y= 1/2 when X = 2
17x 2y + 35 = 0 is what I got for tangent equation.
There was quite a challenging discriminate one. You had to make then 2 equations equal one another, and you get values of:
A= 2P, B = 6p3 and C = 3p7 or something similar.
When solving it, I got P > 1/2 and P< 9/2
I got John to be 27 as (n18)(n+25)
Total money on his birthday something like £1050?
The differentiation one was alright for the most part but I've probably messed up on it. The powers were harsh  can't remember it perfectly.
Feel free to correct me if I'm wrong and share answers if you want. It's just a rough guide of stuff, hopefully the official one will be out soon to stop us all worrying!

1. Simple Intergration remembering C
2. 6y3 ?
3. 2 rout 2, 3 route6
4. Graphs simple
5. Something like 1/3 and 1/7 with minuses cant remember
6. 500 and a proving a2 and a3
7.Long differentiation all i remember is 7/3x^3/2
8. 1/2< P <9/2
9.225 age 27
10. i got area as 35 unit ^2 by spltitting into a rectangle and two triangles but i assume thatd be wrong as people have got something over 3 before.
11. 17x 2y + 35 = 0 41/8 and 17/2 grad
Think area and maybe a part of last Q wrong how much was area worth if anyone can remember, hopefully i get maybe 68/69Post rating:1

Q11(c): I think you've done something wrong, because I got 1/2.
(d): By extension, I think that this is wrong too. I got 2y  17x + 35.Post rating:1

Since 2013, grade boundaries have been fluctuating between 63/64 for an A. The papers were relatively easy comparing to today's though I think so hopefully ours will be lower?

What were the answers to 6?
Was it 54k for a1, as well as 55k+4k^2 for a3.
Then was part b the one where you had to find the sum of the first three terms?
I got 4k^29k+17
Then the last one was 500?
I have a feeling I'm missing something here.

I think 8b was meant to be p>1/2, p<9/2, as they asked 'set of values' instead of 'set values'
