    Grade boundaries:
    A - 22
    B - 18
    C - 13
    D - 9
    E - 4
    U - 1

    Seems about accurate.

    Yes!! what was the shape of your graph?
    Well I plotted each point and then did a line of best fit which just showed a steady increase - wasn't too steep. The actual points themselves didn't form a perfect line or anything, they were slightly scattered either side of the best fit line and then of course the last two were the same value.

    that felt like a paper on enzymes I swear they were in every question, bit confusing. I got 22.5 for the ROR, but I messed up the magnification cos i did the wrong conversion For the graph question did other people get answers x10^-3?
    Yes!!! I got that too x

    If someone can get me a copy of the paper or can remember most the questions I can put together an unofficial mark scheme.

    Predictions on grade boundaries, it's out of 75,?
    It's a new spec so you can't really tell I would think it would be about:
    60 - A
    52 - B
    44 - C
    36 - D
    28 - E

    For the magnification question, who else got something like 21,000? I followed all the steps but I think my answer looks weird, I'm not sure.
    Yeah i got 21,000 too - 84,0000/ 4

    I doubt an A would be 60.
    70-75% is always an A.
    70-75% = about 49-53 for an A.

    I don't think the grade boundaries would be too high considering the new spec and all

    Found that an extremely hard paper. Revised for so long covering every topic. Just to have the exam paper being mostly on enzymes!

    Yes!
    What was your explanation?
    I said that the graph shows that as time passes, the rate of sucrose hydrolysis increases which suggests that the number of plant cells is growing at an increasing rate because this hydrolysis has to occur within the plant cells so more hydrolysis suggests more cells present and thus more growth of the plant. Wasn't entirely sure on this answer but I think that's the sort of thing they were after.
