<p>Is it possible to take an extra subject test (or two) on the testing day when you have only payed for one. I heard that they will just bill you later on although i dont know how this is done. In June i signed up only for Math Lvl 2 but now i also want to take Chemistry and possibly US History. Can i just take the 2 extra exams on test day? Also can i still sign up for more tests on the collegeboards website for june for a late fee or is it already too late?</p>
<p>Ya.. I have the same question. Someone bump please..</p>
<p>You can still sign up for additional tests up until May 10th for an additional 22 dollars.</p>
<p>I'm not positive, but I remember reading somewhere (collegeboard.com?) that you could. You have to ask the proctor or something. I'd suggest checking the website.</p>
