    Not a bad exam at all! Last question was a little tricky. For the question which asks for your answer in terms of ln2, did anyone get a quadratic in terms of ln2?

    I think I may have messed up the question where you had to use the substitution to find the area underneath the curve, I ended up a negative value? I just cancelled the negative sign cos it's an area and was hoping to go back to it but I ran out of time
    I got this too but had no clue why.

    That was a pretty nice paper. I messed up in a couple of places though, that was a shame. Should hopefully still be an A*
