Final Prep
18.03 R05 Spring 2009





The following problems are suggested extra work that will help you be ready for the final. It is a good idea for everyone to go through them, but especially for people who haven't performed that well on the hour exams or that feel shaky about any parts of the material. If you have trouble with a specific topic, let me know and we can meet and discuss it. The due dates are for the people who want to make sure they go over the whole material before the final. There will be no credit given for solving these exercises!
