Wow thats great, best of luck, im predicted AAA in maths physics and business studies. They probably would have been better if I put my head down last year.
Expecting this to be a hard paper

Thank you, I'll need it!

I'm sure you'll do very well this year as your work ethic suggests.

Really? My friends said it was easy because they'd done C3/C4?

[br]3y+4x+20=3y4x+12[br][br]3{y} + 4{x} + 20 = 3{y} - 4{x} + 12[br]

[br]4x+20=4x+12[br][br]\therefore 4x + 20 = -4x + 12[br]

[br]8x+20=12[br][br]\therefore 8x + 20 = 12[br]

[br]8x+8=0[br][br]\therefore 8x + 8 = 0[br]

[br]x=1[br][br]\therefore x=-1[br]

[br]P=(1,163)[br][br]\therefore P = \left(-1, -\dfrac{16}{3}\right)[br]

Hmmm. Hard question. It varies so much. I got 71/75 in my June 2014 mock recently but since then have basically done no past papers haha!

You?

Damn :redface: how on earth did you manage that?! I found that paper ridiculously difficult but that's probably because I hadn't done enough past papers before my mock, looking over it now it doesn't seem that bad I guess but still that's amazing, only if I was that clever :frown: aha
Yeah I just struggle with vectors and parts of exponential models I guess.

I think this is the hardest paper out of all of them. That question to find the rate of change dV/dT took me absolutely ages.
