The DEMO featured below shows you exactly how the training will look once you place into your computer: Navigation Bar, Viewing Area, and Controls. The buttons in the Navigation Bar show the different Lessons in the course. Clicking on a lesson button displays the Topics in the lesson. When you select a topic, the topic movie plays in the Viewing Area. VCR like buttons allows you to stop, Fast-forward, or rewind any section.  It is not necessary to have to take the course from start to finish.
