A standing deferred (SD) exam is an exam written at a later date, while a supplemental exam is an exam provided in addition to the usual exams for a course. Once your faculty has approved your request for a Standing Deferred, you'll need to apply through your Student Service Centre (SSC) to write your SD and supplemental exams. Connect with your academic advising office to learn how to apply for a Standing Deferred.
