    I reckon the difficulty was similar to last year's paper which was 64/72 for an A

    Same to both if you mean k=91
    +/- root 3 for the value of k for the coefficient one too?

    No, A is 3/5 as the 5/3AX gives values

    i.e Sine(5/3X36) = Sine(60)

    So your A is 5/3 for application however the scale factor is 3/5

    A=3/5 whcih when applied goes to 5/3
    K- root3/2

    What? You're confusing the C1 grade boundaries and C2. Last year was 57 for an A.
