not a take-home exam

I have this exam to write. It is not a take-home, but the problem is provided in advance for me to answer it in advance. The exam time consists of writing my solution in long-hand from a set of notes (not a complete solution). Those notes are all I may use during the exam time--no lecture notes.

Thus far (rough work done for the big question/half the marks) it is an exercise in discipline. Hiding in the library basement ought to keep "Sunny. High 17." out of my mind so long as I try to focus on the exam.
