Adding and Dropping Courses

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. The add period for the Winter 2020 semester is now closed. Winter 2020 courses can be dropped until the last day of classes, Friday, April 3, 2020.

When Can I Drop Courses?

Starting in Fall 2019, you can drop a course without academic penalty until the last day of classes of a semester. Note that this is BEFORE the last day of the exam period). Mark that day on your calendar every semester (Fri. Nov. 29, 2019 for Fall 2019 semester).

If extenuating circumstances prevented you from dropping a course, you may want to submit a Request for Academic Consideration to our office.

Note: You cannot drop your last course on WebAdvisor. Doing so would be a withdrawal from the semesterSee "Getting Help" page - withdraw from semester. For that you need to seek the program counsellor's signature.

Exam Schedules: An important part of course selection

Know when your exams are! 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.
