A course is missing from my course form
Report it under Result issues: the University Trail Committee follows it up with your department.
A course appears on your form only when it is on your programme's curriculum for your level and the department has opened it for this semester. A course can also be held back because of a prerequisite you have not passed.
Report it under Result issues on the portal, naming the course code and title, your level, and whether it is a carry-over. The University Trail Committee takes it up with your department, and you can follow each stage there.
