Withdrawal Calendars

Withdrawing from the Semester or Session

If you submit a withdrawal form to the Office of the Registrar and/or drop all your Main Campus classes in a semester or special session without re-enrolling, then you've withdrawn from that semester or session.

Based on the date of your withdrawal, you'll be responsible for paying all assessed tuition and fees as reflected in the refund and assessment schedules below.

Note: Failing to attend classes you're enrolled in does not constitute a withdrawal. If you stop attending class, you're still liable for all applicable tuition and fees, and you'll likely receive a failing grade.
