    integrate xe^(x^2+1)
    Two ways of doing this - by reverse chain rule (inspection) or by substitution of x^2 + 1.

    Inspection should be easiest.

    Pull 1/2 outside the integral and do by inspection.

    Just do all the past papers from 2008 onwards. That's what I'm going to do, the day before the exam.

    I was told that you need to achieve 480 ums for an A and 90% in c3/c4 + an A at AS to achieve an A*

    You don't need an A at as, you need an A (480/600 UMS) overall.

    So someone could average 75 between C1, C2, S1 and S2 but average 90 on C3 and C4 and still manage to get an A*? Amazing

    I find Solomon papers degrading and demotivating as they're unnecessarily hard.
