The following points do not constitute homework you have to do. Keep in mind that it will take time to cover them, and you cannot do them in a week. Keep these points more as a companion for later on when you read the corresponding sections.
Chapters 1, 2: Avoid until you need something in particular from there, or you do it for fun (very low priority)
From chapter 3, we cover section 3.6. An additional section that you could read is 3.4. This section does not directly apply to what we do, but it will help you understand many arguments you will find in other textbooks.
