Withdrawals processed in person are effective the day on which they are made.
Simply ceasing to attend classes or notifying a faculty member does not constitute an effective withdrawal. The last day of class in a given semester is the deadline to withdraw from a course. No tuition refunds are available unless the student withdraws before the end of the second week of classes in the fall and spring semesters or before the end of the first week of classes during the summer semester. Refunds Students receiving financial aid in excess of direct University costs may receive a refund of a valid credit balance. Refund processing begins after financial aid has been applied to students' University accounts, which is never earlier than ten days prior to the beginning of a term.
