Navigating between modules

To navigate back and forth between modules you use the Module Navigator, which is situated in the top area of the Home Screen.
Before you can navigate to a succeeding module you must have completed the current module. Until you do so the succeeding module will be dimmed indicating you cannot select it.
Once you complete a module it will turn green and the succeeding module will become accessible.
As you progress you will be able to navigate between all modules you have completed.
