Change subjects on test day?

<p>hey guys.. is it really possible to change the subjects for the SAT II on test day? cuz i've already registered with one set of subjects but would like to change one.. it's not possible on the homepage but i remember that i heard that the subject choices are not binding..</p>

<p>input plz...</p>

<p>Yeah, you can take as many or as few as you want on the day you go there. If you take more they'll just bill you more. I don't know if you get a refund if you take less though. You just take what you want, you don't have to fill out a form or anything.</p>

<p>wow thanks..
I'm so relieved !</p>
