Help with SAT/Subject test scheduling?

<p>Okay so I was registered for the SAT on October 9th, US History on November 6th, and World History on December 4th.</p>

<p>As far as I know, you can take up to 3 Subject Tests on the same date. I want to reschedule so I take both US History and World History on December 4th and have a second SAT on the November 6th. </p>

<p>I can change the November 6th date fine so I can do the SAT a second time, however when I try to add a new Subject Test is only has available rooms for January 2011 onwards, and when I try to change the test on the December 4th it keeps popping up with a message:</p>

<p>"It is not necessary to make changes to your Subject Tests. As long as you are registered for at least one Subject Test, you can finalize your Subject Test choices on the day of the test. Additional fees may apply. You will be billed after the test."</p>

<p>What does this mean? Does it mean when I arrive at the test center I can do both the World History and the US History without officially registering for US History in advance and I'll just be billed later?</p>

<p>Thanks :).</p>

<p>^^Yep, that’s pretty much what it means.</p>

<p>You have reserved yourself a seat at those testing centers on those dates. Once you’re in there, you can take any subject tests you want to take, up to a maximum of 3.</p>

<p>You will be graded on the ones you take, and then you will be billed for the ones you haven’t already paid for.</p>

<p>All the tests are in one booklet, and you’ll just open the booklet to the one you want to take for the first hour. Then, when the second hour is proctored, you’ll open the book to the next one you want to take.</p>

<p>Easy!</p>

<p>(If, on the other hand, you signed up for three but only took two (let’s say), you would not be refunded any money. You’d simply forfeit the money you already paid for the third.)</p>
