    all apart from an A, being 57
    I'd bet an A was 56, ive looked at the grade boundaries for the last 4 years of June exams and the highest A in those was 55 so i think 56 is reasonable.

    Do you know if I can get full marks on later questions (i.e. part b,c,d..) with an error carried forward from part a? I think I've done this on a number of questions but am not sure how the accuracy mark works.

    Do people think 73/75 on Core 3 and 64 or 65/75 on Core 4 will be enough for 180 on the two?

    Personally I think the grade boundaries are unlikely to go that high, they may be 2 or 3 marks above last year's but not much more. The June 10 Core 4 paper seems easier than the one we all sat today as well.

    Could someone explain 8b(ii) please?
    I thought inverse means that constant k is negative, not that k is divided by the surface area of the circle (which I forgot...)
