    It wasn't too bad, still harder than some of the earlier past papers but much easier than 2012's papers.

    Math C1 edexcel paper was SO hard! No one managed finishing it in our class !
    It was the HARDEST paper ever! :mad:
    glad im not the only one then =/ do you know where any threads are about the edexcel one, if everyone else found it as difficult i think that means they should lower the grade boundaries... hopefully... how much do you think itll be for an a?

    I could probably do a full mark scheme by tonight if everyone posts the questions on here. Get posting!

    I apologize in advance if the questions aren't in the right order

    Prove that k=-4
    Find the gradient of AB
    Find midpoint of AC (can't exactly remember the letters)
    Find equation of line in form x+y+p=0


    Simplify the surds
    the first answer was 2/7
    the second answer was something along the lines of 5+ root 6 (I can't exactly remember what the question asked)

    The circle with centre C (3,-2) has equation x^2+y^2+6x-4y=12
    Find y-coordinates of intersection
    Find radius of circle

    Point P (2,5) (I think these were the coordinates, not entirely sure)

    Find the length of CP.
    I think the answer was root 34.

    Find the length of some other one (can't exactly remember)

    Bird flying over ground questions are below:

    dy/dx = 1/2t^3-?t+? (question marks represent the numbers I can't remember)

    The bird flying over the ground is decreasing, because dy/dx < 0

    d2y/dx2 = 4, so the point is a maximum

    Equation of a line question is below:

    One of the answers which I put down was y=5x-9
    Workings out: 4=5(1)-9

    Then, there was a 5 mark question which we had to use integration + c, we had to integrate dy/dx

    K constant questions:

    Answer to one of them was make them both equal to each other then bring it around to make it equal zero and change signs to show that an equation was equal to zero.


    There's loads more questions missing here on polynomials and k constants. Could someone please finish off my questions and correct any here which need to be corrected.

    Why is there barely anyone going over this AQA C1 paper!

    where is everyone?

    desperately need to check over unofficial mark schemes - i can think of some silly mistakes ive made already


    However it was an extremely easy paper compared to other C1's
    and there was no working out the area from integration, i thought i had the wrong paper

    Same here! Screwed up on the translation question. They were a minus and the intergration question (worked out C in my head but not written on the paper)

    d2y/dx2 = 4, so the point is a maximum
    I'm sure I got it as a minimum point (if the second derivative is positive then it's a minimum, right?).

    what did you guys get for the last one i got
    1/2>k>9/2
    I got k <1\2, k <9\2 because the equation was k^2-20k+18> 0

    Its 1/2>k and k>9/2, they can't be written as one inequality I don't think...
