SAT II's Registration

<p>I am planning on retaking my SAT II's if the scores aren't good, which I'm pretty sure that they aren't (I'm one of the unlucky ones...). I wanna register now so I can get a school nearby. Im going to take a new one for sure, but don't want to register for a retake and then do well and not have to take it. So...if I register for only one now, and take 3 on test day, I know that they would just bill me later for the other two, but my question is if there will be an extra charge for not registerin for them?</p>

<p>plz somebody...</p>
