*Start working on homework sets early.*It takes a lot of time to figure out and properly write a proof.*Read the notes before class and review the lecture notes after class.*We will devote a large portion of class to groupwork, so lecture will be fast, and some parts of the material will be relegated to your reading outside of class.*Carefully commit the definitions and important theorems to memory.*Proving something without knowing the relevant definitions is like eating soup with a fork.*Don't let early material slip by unmastered.*If you don't understand something early in the class or haven't perfected a skill, do not ignore it and hope that it goes away. We will build off of these skills throughout the rest of the course.*Utilize office hours, and not just for homework problems.*My office hours are time set aside specifically for you to talk to me about the course material. You can stop by during any office hour without an appointment or any heads-up. You can also write to ask about meeting me at a different time if you cannot meet me during the regularly scheduled office hours.
