This course has built-in navigation, in the form of the menu buttons, BACK and NEXT buttons, and specific links.
The menu buttons at left are always visible and active, and take you to the named section of the course.
The BACK and NEXT buttons generally take you back one screen and forward one screen, respectively.
In a few instances these buttons perform special navigation functions that should be clear from the context.
The course also includes a Glossary, and Resources, selectable by CLICKING at left.
