* Registration — A withdrawal fee is charged if a student registers and subsequently withdraws. See Withdrawal & Tuition Refund.
** Late Registration/Change of Program — Students must obtain permission from their advisor and course instructor to register after Change of Program. After Change of Program only partial tuition refunds are granted, and only when students withdraw by dropping all of their courses. A late registration fee is charged during and after late registration.
*** Last day to add a class or drop an individual class without financial penalty — There is no tuition refund for courses dropped after this date, unless a student withdraws from the University (i.e., drops all of the courses for which he or she is registered). In addition to any tuition that is retained, a withdrawal fee is charged whenever a student withdraws.
