The Navigation Bar

The Navigation Bar contains links to the seven training sections.  Regardless of your place in the training, the Navigation Bar is always visible.  

You can move from module to module at any time by clicking the module headings.  Thus, if you're in the Special Surveys and a Review section and you need to review something in the Rectangular System, you can click on Rectangular System , review the material, then click on Special Surveys and a Review to return.
