Schedule Changes

The week prior to each standard fall, spring, summer I, or summer II semester is Add-Only Week. Please note that you will be able to add courses, but you will not be able to drop or make schedule changes that require dropping and switching a course during that time. The payment deadline for the semester is the Thursday prior to the first day of classes by 5 p.m. Central Time, and registration will be shut down from 5 p.m. to midnight. Registration will reopen for all schedule changes the next day (Friday).

Please refer to the Academic Calendar for all important dates including registration, add-only week, payment deadlines, census, and last day to drop/withdraw for each semester or part of term.

It is strongly recommended to communicate ALL changes to third-party payers such as Scholarships, VETS Center, Financial Aid, etc.

**Mini-Sessions can be created for any length of time. Please double check Length of Course to determine registration dates and deadlines.
