Course registration: What is a scheduling conflict?
A "scheduling conflict" or a "time conflict" occurs when two classes overlap making it impossible to register for both.
If you try to register for a class that overlaps with a class you are already registered for, you will get an error message saying "erreur d'ajout d'inscription" (registration error) with the course code of the relevant course.
To help you avoid making this mistake, the conflicting classes are greyed out.
