    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

    Anyone ever actually looked at the section in the book on brightness of stars to calculate distances?

    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.
