<p>i signed up for the lit test in june but i'm going to take physics instead.. that's ok right? is there a fee that i have to pay for changing tests?</p>
<p>No, you don't have to pay anything extra unless you're taking an additional test. Other than that, just go there and take whichever subject you want.</p>
<p>All they do is give you an answer sheet and a big book with all the subject tests and then you can choose whichever subjects you want to take (and note the tests you are taking on the answer sheet). It is no big deal.</p>
<p>Ok, thanks guys! :)</p>
