    Thanks a lot Arsey
    Hope u can do the same with S3

    Hopefully 100 UMS for my son
    He thinks grade boundaries will be higher
    Also he achieved early A* by getting
    above 90% at AS

    For the induction question I ran out of time and didn't write the last conclusion step, I proved it was true for n=k+1 and stopped there. How many marks would I have lost ?

    You'd only lose 1 mark. So you'd get 5/6

    Does anyone know how many marks I will lose for the proof by induction question?
    For the matrix, proof by induction question I went straight from -1/4(5^k-1)-5^k, to -1/4(5^k+1 -1)
    I did write the conclusion at the end.

    Shouldn't lose one, but there's only one past question for matrices and it was worth 5, so I have no idea what the extra one is supposed to be for. I did the same thing as you, nonetheless.

    Just realised that for the coordinates of R, I got fuddled and put (3(p+q),3pq) as the coordinates. In my working above you can clearly see me put x = 3pq and y= 3(p+q) and in past paper mark schemes, edexcel seem to vary a lot with the requirement for writing coordinates, so I don't know how many marks I've lost...

    I don't think we'll get the whole 6 marks.
    If we're lucky, we'll get 5 if not 4.
    I think you may get the 6th mark by showing how you get from -1/4(5^k-1)-5^k, to -1/4(5^k+1 -1)

    I know you hate answering these questions but do you honestly think the FP1 paper could be less than 60 for an A like some people are suggesting?

    I really cannot see it. Only once in the 11 papers has it been under 61, only twice under 62, for an A. It had a couple of tricky bits but it really wasn't that hard.

    I'd randomly guess 62.
