<p>This is what I found from the college board website:</p>
<p>Score Cancellation
Score cancellation deletes an AP Exam score permanently from your records. Scores may be canceled at any time. However, for scores not to appear on the current year’s score report, AP services must receive a signed, written request by mail or fax by June 15. Please complete the Score Cancellation Form (.pdf/113KB) and return it to the address or fax number indicated. While there is no fee for this service, your exam fee is not refunded. The score report that you and your school receive will indicate that the score has been canceled.</p>
