    For question 6b, does anyone know why I got C as being (-9,-2,18)? I have seen quite a few others have got that, will I pick up any method marks? And for part c, I found 1/2 of AC and 3/2 of AC and added it onto OB, will I get any method marks for this?

    Yeah -3/4 was the correct one. Then you inverse that and substitute into the x =... And find x coordinate.

    You should get at least half the marks for getting up to that

    Having seen both papers, I think it will be:
    64 for an A* in core 3
    64 for an A* in core 4.

    I did it up to sinq= -3/4 and sinq=1/2

    but then i just sin inverse'd it and i rejected one of the values

    how many marks do you think that'll get me?

    inverting finds q

    unless you plugged it back in cos2q then you would miss those last marks

    if it was out of around 7
    I think you would miss 2-3

    You really think they'll be equal marks?

    That normal cutting the curve again was a hard question, I think very few people must've got that.
    I thought it was quite tricky, I didn't realise how to do it until I'd left it and gone back to it, but I haven't really heard anyone complaining about it so maybe it wasn't as bad as I thought.

    I believe the mark scheme is right. (I'm not bragging - I didn't get half the answers I've added the the mark scheme - it's been a collective effort haha).

    I do since core 4 contained a large number of easily accessible marks, the first few questions were very straightforward. The only challenging parts were normal tangent intersecting (3 marks easily accessible here), vectors last part. Core 3 had a similar number of challenging parts I thought.

    Depends on the ums but in terms of marks I think 72 on C3 and 69 on C4. Hopefully should be 200

    You? @cd

    but you missed out k. It does not equal to 0, it equals to k which is (1/4)-ln2
    .correct me if i am wrong
    K is a number that differentiates to zero

    Well it was out of 7. You would miss one for finding c, one for rearranging and maybe one for substituting x and t?

    So maybe 3, or 4 marks?
