Read through your coursework notes and any of your workbooks.

This should give you a overview of the course, plus its important topics and themes.

If any notes are missing, borrow some from a friend and copy them.

Write them out if possible - or take a photocopy.

Avoid leaving gaps in your knowledge if possible.

Even if you don't revise every topic, an awareness of the whole course will help you make connections between its parts.
