You can see all courses you have accessed and track your progress on any course on the My Studio dashboard page. You can access this through the 'My Studio' link in the Big Look header, or in the course player. As such, the My Studio page is the perfect launchpad for you to resume your progress on any of your courses.
For a course to appear in the My Studio dashboard you will need to have accessed the course in the course player already at least once. When you begin a new course by opening it in the course player, the first thing you will see is the course title card which appears momentarily. Once this has fully loaded you are free to navigate back to the My Studio page where the course should now appear.
The most recent course accessed will always appear first in the list on the My Studio page.
