“Unsubmitted Acceptance” appears on the Choices/Offers screen after you click on an offer and accept it.

At this point, you have indicated that you want to accept a specific offer but have not submitted the acceptance to the OUAC.

To properly accept the offer of admission, click “Review and Submit” and complete the submit process. You will receive a confirmation number by email along with a summary of your responses to offers of admission and/or changes to your application information. Keep this email for your records.
