    I've heard only 100-150 people actually take this A2 - has anyone else heard this?

    I'm only in AS right now and I didn't know it was that low, but now I see why.

    Edit: where did you heard that btw? xD

    Edit 2:
    You can find last years ocr result statistics and it says around 4000 people were examined for this a2 course but yeah even then, 4000 isnt that high

    Im sure I heard it from somewhere - forgot where now! Think I saw it on some centre note of stat thing - it seemed silly, so I thought I'd check.

    Could someone please post a good solution for this question? The mark scheme is messy and unclear.

    p = \dfrac{F}{A}

    p = \dfrac{mv^2}{2r} \times \dfrac{1}{2\pi r^2}

    p = \dfrac{mv^2}{4\pi r^3}

    But 3V = 4\pi r^3, and there are N particles. Hence:

    p = \dfrac{Nmv^2}{3V}

    Essentially the axis are swapped so it's a time-distance curve

    I'm sure the C-13 showed a carbonyl group

    But I have the wrong Benzene splitting

    Yeah, but i'm not really sure what they could ask? The process? Maybe provide a formula and you stick some numbers in?

    Tbh I completely forgot that was on the course. You can probably wing it, that section is just common sense.

    Sorry, wrong thread
    do you do chemistry?
    I'm pretty sure there was a carbonyl C13 one, others have said that too...
