<p>I think you are referring to </p>
<p>National AP Scholar
Granted to students in the United States who receive an average grade of at least 4 on all AP Exams taken, and grades of 4 or higher on eight or more of these exams.</p>
<p>Personally, I do not think it is worth it. You do not get money for it. You do not get anything for it but a certificate in the mail. Yes, you can receive college credit for it (but it all depends on the college). That is the only reason it is worth self-studying, in my opinion.</p>
