* Day 1 * The problem set has writing on it, and the answer sheet has been used (therefore, the Day 1 answer sheet is not included). * Day 2, Day 3 * There is no writing on the problem sets or answer sheets (there is a fold in the Day 2 problem set, but I think it does not interfere with use). There are no board notes. Answers and explanations are included for all three days.
