    Well I doubt a lot of people would have got full marks in the paper to say the least!! Can't tell though, but I reckon they will have to be significantly lower.
    Nearly did, I integrated, instead of differentiating for question 7. I'm completely hurt

    Unlucky!!! My min mark I can get is 63 and max is 73 - would love a 70+ but I've definitely missed out on 100ums I think !

    Question 5 you were supposed add no subtract to get y as y = 1-4x so u = 11/7 and 7/3

    EDEXCEL C1:
    Q1) 2/5X^3-8X^1/2+3X+C
    Q2) y=6X+2
    Q3)a) 2root 2
    b) 3root 6
    Q4a) stretch in y-direction by scale factor 3.
    b) translate by vector (0,-4) (downwards)
    Q5) X=-1/7 ; Y= -1/3 X=-3/7 ; Y=1/3
    Q6)a) A2= 5-4K A3= 5-5K+4K^2
    B) 4K^2-9k+1
    C)I) I forgot to do again lol
    C)II) 500 (OMFG WAT WAS THIS?!)
    Q7)dy/dx= 6X+2X^-2/3+X^1/2+7/6(X^3/2)
    Q8)a) proof of inequality- had to substitute the 2 equations and the discriminant<0
    b) 1/2<P<9/2
    Q9)a) £225
    b) £180
    c) £1710
    d) 18 years from 10 years old so 27 years old
    Q10)a) 5Y+3X-44=0 b) R: (44/3,0) c) area of Quad: 76 units (this proved extremely difficult when splitting into 2 triangles, so I split in 2 triangles and a rectangle)
    Q11)a) dy/dx= 6X^2+2KX+5
    b) K=41/8=5.125
    c) y co-ordinate- 49/2
    D) 2y-17x-83=0

    give the correct answer if any of these are wrong and ill edit it

    Q10 c) is 815/15 which is 163/3, 54.333
    i got 1783/15 tho XD
    I calculated the area of the big triangle and take away the area of the small triangle, but i forgot to divide the area by two when calculating the big triangle lol.

    I got Q10 c) area = 163/3
    Q11c) 1/2
    d) 2y-17x-35=0
    for Q2 im pretty sure it was 9^2x+1 instead of 3x+1 :'(
    making y equal to 2x+4

    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 17x-2y + 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 agree with TRUEDAN it was definitely a fraction, I got my fraction out of 6 but I guess it was unsimplified
