Notes:

1. You will need to fit two or three hour exams into the above schedule.
2. The text is very readable. Much of the content of the text is in the exercises, so many of the exercises should be covered, either during discussion/problem-solving sessions in class or as work done outside of class.
3. This class often has a small enrollment; 10-15 students. It is both possible and very useful to have students present their work at the board on a regular basis.
