Students that just registered will not be able to see the "My Courses" item in the left navigation drawer, because they are not enrolled yet in any courses.
The course page can then only be accessed through a button on the bottom of the left navigation drawer, which does not have a name, but merely an icon.
The button needs to indicate more obviously that it links to the course page OR the "My Courses" item should always show, even if not enrolled into any courses.
