    This is what I did:

    OL gradient is -3/4 (so my y was 7.5 and my x was 10).

    Furthest point was the intercept of x + y ≤ 32 and 2x + 3y ≤ 72 (iirc), used simultaneous equation and got x = 24 and y = 8.

    P = 15(24) + 20(8) = £520

    Right- grade boundary predictions. I think the grade boundaries will be higher than 2015/2014! But of a blow after core 3!

    I got 6, I think the question asked for the max number of comparisons in the 6th pass

    Yes it did but only for the 6th pass, so the 6 and 7th element are compared then shuttles down the list comparing with the other 5
