    For the second part just use your dv by dx from part one and set equal to zero and solve to find v which would be x and then find the corresponding y value, part 3 you factorise the equation and part 4 you show the discriminant (b squared minus 4ac) equals zero

    Yeah, I've done pretty much all the papers from 08 to 2014 so thought I'd find some more for extra revision!

    Awww Hopefully we both do better than expected. You've still got Core 2 soon. That exam is a lot better than Core 1 (in my opinion).

    Maybe next time you can try across boards.

    The TOTAL contents of C1 and C2 are the same in all boards except the topics can appear in slightly different modules.

    sometimes you need a bit of luck too, like having a good day, so to speak.

    All the best.
