<p>Is this possible without going "standby"?
I registered for the December ACT, but if I want to switch test centers, is there a way to do so online? I don't want to just go to the test center I want, in fear of it being full (which I think it is very close to) and not being able to go back to my registered center to take the test...</p>
<p>go to the test center you signed up for. because december is popular for the last chance to take the test, you will most likely get shut out of the center that you want. i remember how there were a good 15 people who couldnt take the test or had to wait an hour to get into the test center i was at because they decided they didnt want to drive 45 minutes away to take the ACT, instead of the 5 that it took them to get at the desired center</p>
