Final exam

There is a comprehensive final exam on May 2 Tuesday, in our normal classroom at the normal time but lasting until 5:40 PM. (You can also arrange to take it at a different time May 1–5.) To speed up grading at the end of the term, the exam is multiple choice, with no partial credit.

For the exam, you may use one sheet of notes that you wrote yourself. However, you may not use your book or anything else not written by you. You certainly should not talk to other people! Calculators are allowed, although you shouldn't really need one, but not communication devices (like cell phones).

The exam consists of questions similar in style and content to those in the practice final exam (DjVu).
