<p>I signed up for SAT I on collegeboard website for June 4th, but now I decided I want to take the US history subject test instead since I'm well prepared for that more. Is there a way to change it on the site or can I request to change it at the test date?</p>
<p>You can change it on the website, but you have to pay like $24 (by credit card) or something ridiculous like that. CollegeBoard is $$$ hungry. :|</p>
