Please be advised that if you enroll into courses after the payment deadline, late fees apply. 

If you have already paid for your courses, and decide to add an additional course before the add deadline, the tuition and fees for your new course are due immediately.

If you add courses after the cancellation date has passed, you are responsible for all tuition and fees associated with your enrollment.  You may be cancelled for non-payment if payment is not received immediatelyIf you fail to drop your courses, you are also responsible for tuition and fees. 

If a student drops a course and adds a new course after the refund deadline, the student will be responsible for the fees for both courses. Tuition and campus-based fees will not reverse for a course dropped after the refund deadline. Late fees will apply because the course is added late.

If you were added to a class from a waitlist after the payment deadline, please contact Summer Session Office at to reverse the late fee.

If you wish to add a class after the Deadline to Add a Class, you will need to submit a Late Add Request via the Enrollment Authorization System (EASy).  Late adds are not guaranteed. If you are approved, payment is due right away. For more information, visit the How to Add a Class page on TritonLink.
