What was the question for k=4 and k=20?
giant quadratic one
like there was 80 in there somewhere when simplified, all I remember is:
I think a =2, b = k+4 c = 4(k2)

Wait, are we 100% positive the first question asked for a parallel line? I could have sworn it said perpendicular and gave 5/3 as my gradient...

Is 6b supposed to be 7b? I'm pretty sure Q was part of the integration question.
I feel like the differentiation may have been 7a? Wasn't there a question that started differentiated? That may have been Q4.

Are you sure for question 4 b it said 3 linear factors not 2? Because I put it in 2 linear factors and I'm sure that's what it said to do not 3

6a was 4 marks I think, you had to find dy/dx then sub it in.

ANYONE WITH GENERIC QUESTIONS, PLEASE ASK ON THE GENERAL FORUM AT http://www.thestudentroom.co.uk/show....php?t=4077801.
Before you ask, check if it is answered before on this, that (or another) forum. This forum is specifically for the mark scheme, and discussion around marks etc only.

Hi everyone, I'm pretty sure I've got almost everything correct but for the length of CT, I stupidly left it as root 81 instead of 9. Do you think they may allow it in the mark scheme as normally it says OE (or equivalent) and root 81 is equivalent to 9!
Thanks

I figured out the coordinates of B using vectors :P. Too used to doing C4, just hoping that this tricky C1 test doesn't reflect how difficult they plan on making C3/4. (Doing full ALevel this year)

Does anyone remember how much of Q1 would be screwed up by giving the wrong gradient for 1a? I think every other answer I gave on the paper was correct, but I'm genuinely panicking about this one. I don't remember even doing Q1, which says it all really...Last edited by Cassette; 18052016 at 18:06.
