If you want to withdraw from just a few courses, you need to do this through the add/drop feature on banner
If you want to withdraw from the entire program you must withdraw in writing with a signature. This can be done by filling out the withdrawal form found on the web or sending a letter but it must be signed.
You have until 4:30pm on Sept 17th to withdraw and receive a refund or have your balance owing adjusted. After this date you will be responsible for paying the full semesters fees.
Between Sept 18th and the last day to withdraw, you can withdraw from your program (your transcript will show a grade of WD beside all of your courses) but you are not eligible for any kind of refund
