There are two different types of deadlines when it comes to cancelling courses:

1. Last day to cancel a course without academic penalty. This is the last day to cancel an individual course so that it disappears from your permanent academic record. View the list of deadlines for cancelling a course without academic penalty on the Faculty of Arts & Science website. 
2. Last day to cancel a course and receive a full or partial refund. View the refund schedule on the Student Accounts website.
