METHODS EXAM 2 SOLUTIONS

Exam 2s take a while to write up. Sorry 'bout that. We've probably made a few typos / minor errors. If you spot one, let me know, and I'll fix it maybe tomorrow.

Got completely lost towards the end of q2 and q5 but other than that pretty happy with it. Had to guess 3 multi choice. Now I can only hope I didn’t do anything stupid.
