    That was a bit tougher than P1 but still pretty good! Hoping for a B :)

    The only theorem I didn't learn came up aw I'm an absolute idiot -_- should have learnt them!
    Rest of the paper was lovely though, if I'd known the theorem I'd say I'd have gotten nearly full marks

    I got that at first too but then I realised I had marked the wrong angles as being equal. I got 3.6 and 15 in the end

    You had to add 9 onto the 3.6. :)

    Is it true you lose marks for writing in pencil?? Please not be true, aiming for the A.

    I don't think so - it's just people are advised from writing in pencil as it fades over time.

    Anyone know how to prove the rectangle was a rectangle and also was it divide by 100 or 10000 for the box question seeing as it was squared?

    PS. That theorem of the circle was such a surprise, good thing I learned it the day before, I had doubts it would come up after seeing it in a previous exam paper.

    I used congruent triangles, though, I'm sure there was other methods.
    For the box question, I did the question in metres, but I think it's dividing by 10000 as 1m^2 = 10000cm^2.

    Doesnt 70 euro seem a bit large for a cardboard box though? And also there is no way those thing were like 100 metres squared
