<p>I'm kinda confused about this. I signed up to take my subject tests on May 6, but now that I think about it, I want to change which tests I'm doing. The website says I can just change the tests at the test center. Is this true? How will they know to send extra tests in that subject, or are all of the subjects in one test booklet? Does this cost $20 or $20 per change? How do I pay, by check?</p>
<p>I really don't know much about the SAT. I took the April reasoning test, and there were 5 people (me included) at the test center, this included people within about a 100 mile radius. The SAT does not have priority here, so I don't have much local help.</p>
<p>Any (other) helpful hints will be very appreciated.</p>
