With the exception of the Returning Student Optional Shortcut, the Basic, Advanced, Military, and International courses all have the same general structure. All the lessons you need to complete your certification are within the certification course menus. You should take the lessons in a linear sequence.
Click the Basic through International icons on the screen to learn more about each certification path.
The course menu for each course is always available to allow you to navigate through a course's lessons. Once you begin a lesson, a Course Menu button is available.
