<p>What if I signed up for one, and one the test day, I decide to take another one one top of that. Am I allowed to stay for another hour and take another test? If so, how does college board collect the fee for that extra test?</p>
<p>What if I signed up for 2, and I realize I'm not ready for one on test day. Can I just take the one I'm ready for and leave? If I do, Collegeboard won't cancel that test right?</p>
