Go Daddy also offers domain back-orders, but they do not use a network of drop registrars (all of their registrars are owned by the Go Daddy Group, Inc.).
Caution: If a schedule adjustment has required an exception by a department or the Registrar's office to override an established limit in ISIS (e.g., adding a course that creates an overload, is controlled, or is full), the system no longer prevents time conflicts, so students should check their schedules carefully.
It is possible to drop a course after the drop/add period but before the late drop deadline, which, for full-semester courses, is listed on the Academic Calendar.
It may be possible for a student who began a sequence of courses at too high a level to drop down to a more appropriate course in the sequence after the drop/add period without using late drop credits.
