Can you try refreshing your courses page? You can do this by clicking the 'Grade Report' tab in the toolbar, and then toggling back to the home page. 


I'll attach a link to a step-by-step video that may clarify things:

You can also log in to the student account directly via tcalearn.com and all courses and assignment will show.


Let me know if that helps!
