1. Match the lecture to the problem set that covers the same material.
2. Copy sample problems from these lecture notes onto a blank sheet of paper. You don’t have to copy the steps or the answers, just the questions.
3. Label the blank sheet of paper with the date of the lecture. This will help you later figure out where these problems came from (and more important, where their answers can be found).
4. Fasten this sheet with a paper clip to the problem set you matched it to in step one
