Academic Dates and Deadlines

The academic dates and deadlines below include enrolment dates, drop deadlines, assessment periods, petition deadlines and more.

It is important to take note of all academic dates, and payment and refund deadlines. Your refund eligibility depends on a variety of factors including how your fees are assessed and on what date you cancelled the course. Please note that the course add/drop dates are not the same as the fee refund schedule. Deadlines for fee payment, fee refund schedules and other financial dates are posted on the Student Accounts website.

Being unaware of an academic, payment or refund deadline is not typically accepted as a valid reason to be granted an exception or an extension.
