If you drop classes during the drop and add period, you will be reimbursed for the difference. If you withdraw from classes after the drop and add period, you DO NOT receive any refund. If you resign (withdraw from all of your classes), you may receive a refund based on when you resign. The longer you wait, the less you will get back. If you wait too long, you will receive no refund. Check the class schedule listing online for the refund schedule.
