<p>So if I never signed up for a college on my AP booklets in the past years, when should I send my scores? Should I do it after I am accepted or before?</p>
<p>You send them only to the school that you will attend. So you send them once you know which school that is.</p>
<p>If you take AP exams in the May of your senior year, you can pick one college to which you send all your scores (for free, I believe). By May, you’ll know which college you’ll attend, so you can just fill in that particular school’s CEEB code.</p>
