    I guess 58. You heard it here first.

    I did this paper how did people find it
    I thought it wasn't too bad although I know I made some silly little mistakes which I'm killing myself for, what do you think the grade boundaries will be like?

    Really? Was it a hard paper then?? I haven't done many others...

    Does Mr M release anything for OCR as a mark scheme? If so, anyone want to hazard a guess as for when?
    Likely to be tonight or not at all.

    Well it had something new (the last question) combined with that k thing which was quite tricky and seems to have tripped up a lot of people, so add those 2 to the fact that normally the A boundary on a very standard nothing special C1 paper is about 61, you have around 58.

    I would guess more at around 62-64 for an A, it was fairly average.
    Likely to be ~68 for 90 UMS

    Actually finding three points and an area has definitely come up before, because I remembered it said 'units squared' on the mark scheme which I remembered to put in the exam today. I didn't think the paper was particularly hard or easy, I'd guess 62 for an A.

    I think it was out of 5...

    2 for finding 3 points
    2 for finding base + perpendicular height
    1 for final answer (40 square units)

    (Probably)

    More likely to be 2/4, but you might get the mark depending on the RHS of the markscheme.

    Hi can I just briefly turn attention to a C2 question I'm having a bit of trouble with (I know it ought to be easy, and I'm sure it is...!)

    Can anyone help me out with this:

    7x = 2x+1

    Solve for x.

    So far, I've got up to here:
    log7x = log2x+1
    xlog7 = (x+1)log2

    I have no idea where to go from here! Normally you can just divide by logs to find the x solution and then act as necessary but the way to do this isn't appearing in my head! Thanks!!

    that is what i got but it is not a right angle triangle answer is 40
    Yeah I just realised that, it was only 4 marks though and we'll probably get at least 2 for method and I thought the rest of the paper was pretty easy so fingers crossed!
    How did you find the rest?

    How are you sure it was 40 square units :hmmm:.Everyone seems to have different answers for that question.

    From this, expand the right to get:
    xlog7 = xlog2 + log2

    Collect like terms:
    xlog7 - xlog2 = log2

    Factorise:
    x (log7 - log2) = log 2

    Use log rule with subtracting -> dividing:
    x (log(7/2)) = log 2

    Divide:
    x = log2 / log(7/2)

    Hope that helped

    You know for the pqr question, if i got the right points, but made an error in writing it down on a lower line (i changed my (0,8) to (0,4) for some reason) How many marks would i lose, with the right points for p and r and but with an incorrect area (i put down 21 instead of 40)
