Note: prior to Fall 1999 I gave three Midterms and a Final; the last midterm was the day and time of the final, so the final was only a one-hour exam. I switched to using a single midterm and a comprehensive final in Fall 1999.
Some semesters I've been more successful than others at producing sample solutions, especially on the Final. If I don't show a sample solution in this list, I don't have one in my archives.
