Total Registration's system allows students to request the cancellation of an exam. This exam cancellation must be approved by the school, therefore your exam will not be canceled until it is approved by your school. If your school denies the cancellation request, your exam will not be canceled. The school sets their refund/cancellation policy.
To request the cancellation of an exam registration, please visit TotalRegistration.net and log in with the student's email address and password created at registration, click the service/exam (AP, PSAT/NMSQT, or IB) you wish to cancel, and then click the link to request cancellation.
The school's refund policy will display above the cancellation request form. See EXAMPLE below from Test School (Your school's actual policy will vary)
To request a cancelation, check the box next to the exam(s) to cancel and click "Next". On the next page, you will need to indicate the reason for requesting a cancellation and then click "Send Cancellation Request".
