    any reminders of what you had to do in each question and the answers they got?

    remember

    3)r cos(x-a)

    6 or 7) arcsinx

    9)expontential
    Q3) R is (2^2+1)^0.5 =5^0.5
    a= arctan1/2

    7) arcsin(x+1)=pi/3
    Sin(pi/3)=x+1
    -3^0.5/2=x+1
    x=-3^0.5/2-1

    I thought thay exam was awful, not only was it difficult, it also required you to be very fast.
    I was working as fast as I could and I still didn't finish q9 b&c.

    Usually I can do a c3 paper within 50 minutes to an hour. But last years paper (which I did at home) and this years paper takes me far longer. It is the first time doing a c3 paper that I felt time pressure
    Grade boundaries ought to be low.

    How did you end up getting that? I didn't have a clue how to do that one haha
    R^2= 2^2 + (-1)^2
    Alpha= arctan(1/2)
