Lovely paper IMO.
Agree with almost all of Qcomber's answers.
I think I got -1/52 or something similar for Q2), maybe wrong though/
T2 was also a clockwise rotation of 150 degrees about y-axis, not sure if MS cares whether you state direction
does anyone remember how many marks each question was worth?
What was the remaining factor in the factorising determinants question?

I think I got a+3 but I can't really remember that well

Think I got that. Someone said a-1 so I was a bit worried. Personally, I preferred FP3 to this exam. Too many places for silly mistakes and unforgiving grade boundaries.
What grade boundaries are people expecting?
Does anyone know how many marks q6 was worth?

1+3+5 marks
Am I the only one who is thinking that I did badly in this paper...I feel I performed better in the fp3 paper than this one. I supposed it was a mistake for me to practice older past papers rather than the latest ones (2014/2015).

Got pretty much the same, think Y was -41/12 a? I didn't cancel down though, so got -44/24, -82/24 and 102/24, do you think I'd lose a mark?


Nah don't think they asked for exact form I reckon you'll be ite
Am I the only one who got - 32 for the determinant 3 marker
I got -32 as the determinant for inverse B, they wanted det B so it was 1/-32

Wait did they give you the matrix AB or the matrix AB^-1?

Well **** I didn't read it properly then I gave detB^-1

a-1 was 3rd factor, i think

I think you messed up something on 6.

Yes i did, pretty confident about the rest though, hopefully still an A*

Quite strange that Q2 seems to have such a mixed response. People at my school aswell seem to be all getting different answers.
