When Can I Add Courses?

You can add courses for the upcoming semester in a specific "window" during the University's course selection periods. Your course selection window can be found under our "Course Selection" tab at the top of this web page. The "Add Period" is when you can change your schedule. When the add period ends, you can no longer add courses to your schedule.

Exam schedule: an important part of course selection/adding courses

Add each course exam to your calendar and triple check that you have no conflicts (overlapping times) and that this exam schedule will work for you. An exam conflict is only an exact overlap. If you have an exact exam conflict, you should drop one of the courses whose exam overlaps. If it is a required course for your major and cannot be taken in the next semester, see your Program Counsellor. More than two exams in one day or more than three exams in two days does not constitute a conflict. Click here for the exam schedule

When Can I Drop Courses?

You can drop courses until the last day of classes. See the "Schedule of Dates" in the current undergraduate calendar to find the last day of classes. You should also consider the "tuition refund schedule.
