<p>Are you guys sure this is possible and that they won't just cancel one?..</p>
<p>Yeah, you can. They'll bill you later for it.</p>
<p>Can anyone else confirm?</p>
<p>I went to the CB site and found this: </p>
<p>"You may substitute a Subject Test (other than a listening test), or add Subject Tests (other than a listening test) on test day."</p>
<p>Yah you can call them up even today and ask even though the registration deadline is over because you already registered for that day. It'll cost you the price of one SAT II test as well as some additional fee. </p>
<p>I had wanted to change my SAT I to three SAT II's and I called them and they would have done it but I was happy with my scores when I received them so I didnt. But I know for a fact it is possible.</p>
<p>Thanks guys, didn't even think of going to the cb site.</p>
<p>There is an amazing amount of information on the CB site if you take the time to look around. Sometimes I'll google something that takes me to a part of the CB site that I never would have found by starting on their site.</p>
<p>Can someone confirm if you can only take 1 or 2 of the subject tests even though you registered for 3? Because I don't see that anywhere on the collegeboard site?</p>
