Previous semesters' exams can be found at PreviousExams.zip. You may also want to see the previous exams we posted for the first exam.

The best way to prepare is to practice problems (e.g., previous exams) and problems you can come up as you study. The more you practice, the better you will do in the exam. If you just practice one or two exams, that is probably not enough.
