    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?

3{y} + 4{x} + 20 = 3{y} - 4{x} + 12

    

\therefore 4x + 20 = -4x + 12

    

\therefore 8x + 20 = 12

    

\therefore 8x + 8 = 0

    

\therefore x=-1

    

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

    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!

    Damn 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 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.
