All course content is located in the Course tab. Once you enter the Course tab, the navigation for the course lessons will be located on the left side of the page. Click on the title of the first lesson to begin. Each lesson contains several sections, or content pages. You can use the arrows at the top and the bottom of the content page to navigate between sections. When you have reached the last section of the lesson, the forward arrow will be grayed out, and you will not be able to move forward. At that point, you should move to the next lesson by clicking on its title in the left navigation.
If you exit the course and later re-enter it, you will receive a message that reminds you of which lesson you were most recently in. If you click on the hyperlinked lesson title, you will be taken to the lesson and section where you left off. You can re-enter lessons you have already viewed at any time. Note that when you re-enter a lesson, you will always be taken to the section you have most recently viewed.
