Each course has 2 documents associated with it:
1. Course with links (Google Slides; below) – Click somewhere within the presentation area below, then use the left and right arrow keys on the *keyboard* to navigate the slides. Clicking the arrows with the cursor each time will keep taking you to the top of the page.
2. Workbook (Google Sheets) – When you open the workbook, you will be asked to “Make A Copy”. This is to prevent the original from being changed.
