  • Why can I not find all my registered courses on Canvas?

    Once the course / section record has been added / dropped in your Weekly Schedule of AIMS successfully, the course list in Canvas will be updated in the next morning 1.

    You may not have access to all of your registered courses in All Courses list on Canvas as some of your registered courses may be not published 2.
