Final exam

There will be a comprehensive final exam on May 3 Monday, in our normal classroom at the normal time but lasting until 7:10 PM. (You can also arrange to take it at a different time from April 30 to May 6.) To speed up grading at the end of the term, the exam will be multiple choice, with no partial credit.

For the exam, you may use one sheet of notes that you wrote yourself; please take a scan or a picture of this (both sides) and submit it on Canvas. 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 on MyLab.
