I just wrote a brief email. Dear Admission, I would like to withdraw my acceptance from xxxxx school.You can download our sample letter in PDF form here: Notification of Intent to Withdraw a Student. I am writing this letter to withdraw my admission. It is to humbly request you to kindly cancel my admission. Mail a letter requesting withdrawal from the University. The letter must be signed and can be mailed to: Illinois State. If it is during the summer term, and it is your only course, you will be required to fill out a withdrawal form instead of this petition. I must decline your offer of acceptance and withdraw from my seat in your incoming class. However I am still willing to accept your generous scholarship.
