<p>Wow, you went to a really bizarre school. At my school I brought my phone in the actual testing station and left it on a nearby table. I didn’t have a proctor because I was the only one taking the exam (it was a self study so my teacher ordered it). I could have checked it at any time (I’d never do that though, the AP was easy enough anyway). The fact that they’re taking your phone overnight to check to see if you’ve cheated is a little over the top. Maybe they’ve had to deal with a lot of cheating incidents in the past so now they’re overbearing and annoying.</p>
