If you are on the Carmen landing page and are trying to access older courses, here’s a simple trick to make them show up.
Click on the “Load More Courses” button on the right side under Filter.
Now you’ll see more courses. In this example, the list now includes SU16 and AU16. The search feature will also find your older courses from those semesters.
To go back to viewing more recent courses, click on the same button (which now says “Hide Added Courses”).
