The "Tracking" page is where you can see all of the courses that you have completed taking at HES.
A course must be marked as "Complete" when you created (or edited) the course for it to appear on the "Tracking" page.
All of the statistical information on the "Tracking" page reflects only the courses you have completed at HES. Thus the "Tracking" page allows you to see your current situation at HES and all of the degree requirements you have fulfilled.
The "Tracking" page also reflects any tests or transfer credit that you have marked as "Completed." You can create tests and transfer credit "courses" by clicking on any of the "Create a new course" buttons.
If you're interested in planning out your future courses, that is what the "Planning" page is for!
