SAT Subject test, adding a subject test on test day?

<p>So here's the thing: I've already applied for the January 23rd SAT Subject test (Chemistry). I now want to do the Physics SAT II.</p>

<p>I tried changing my SAT application through the "Change my test center" option, but everytime I try to add in Physics by clicking on the check box I get a prompt telling me that "You can choose additional SAT II subjects on test day" or something.</p>

<p>So what does that mean? Even though I only registered for Chemistry, I can also take the Physics by just doing it on the day of the exam?</p>

<p>Do I bring actual money with me to hand over to the supervisors...? How does it work? Note that I'm not living in the United States, but in Dubai (UAE)</p>

<p>A quick reply would be nice!</p>

<p>I called and asked this question when my son took the subject tests a while ago. The answer then was that you show up on test day, and at the registration table you can choose to take any of the tests - you don’t even have to take the one you signed up for originally. You can take one, two, or three tests, and you will be billed for any that you haven’t already paid for. It’s incredibly easy and flexible.</p>

<p>All that being said, you should pick up the phone and call college board and just make sure you get the same answer - you’ll fell better knowing that you confirmed it yourself.</p>
