Table of Contents
Once you are working through the lessons you will see on the left side of every screen the Table of Contents for the current lesson. (There may be a block of information like the QuickLinks above it.) This allows you to select any part of the lesson in case you need to go back and review something you have just learned.
For example let’s try it now. On the left side is the “Lessons and Days” link. Click this and then click "The Professor” link.
To go back to the Table of Contents, click the Year 1 tab at the top of the screen.
