<p>Hi, I'm trying to cancel my Psychology AP exam score, but I don't know what to put for the blank next to Form on the AP Score cancellation form? I took the exam at a regularly scheduled time, and I remember that last year's form number was 4HBP, but i don't know if that applies again for this year.</p>
<p>The form is on <a href="http://media.collegeboard.com/digitalServices/pdf/miscellaneous/AP_Score_Cancellation_Form_2011-12.pdf%5B/url%5D">http://media.collegeboard.com/digitalServices/pdf/miscellaneous/AP_Score_Cancellation_Form_2011-12.pdf</a></p>
