Old Exam Problems: 
Here are some old exam problems that I have written and given to 21241 students in previous semesters. Before the questions come in  no, I don't have solutions available for these problems. You have a large number of problems from the text with answers, and it's important for you to get used to working on problems where the answers are not available. You'll have a chance to ask questions at the Review Session, and during your TA's office hours, too.
