<p>On the website, it seems like it is March 1st. But I called their offices a few days ago and they said it was April 1st. When's the real deadline?</p>
<p>Well, we haven't started registering for APs yet, even though my teachers have already suddenly jumped into OMG-APS-ARE-AROUND-THE-CORNER-LET'S-CRAM mode on Monday, so I assume registration for us is soon.</p>
<p>Each school has its own registration dates. At my school, we're doing registration March 1st to 3rd and if you miss it, no AP exams for you.</p>
