<p>(It is obvious that I have very limited knowledge of how the Subject Tests work.) Alright, here's the situation: </p>
<p>I'm registered for two June 7 Subject Tests: Literature and Math Level 1. Recently, however, I've decided that I'd rather take US History than Math Level 1. So do I have to change my registration with Collegeboard, or can I simply take a different test on June 7?</p>

You'll be given a booklet with all of the subjects in it. For your first test, you will open the booklet to the appropriate subject, and copy the test's code into your answer sheet.</p>
<p>After the first test is finished, there is usually about a 5 minute break before the 2nd test. Again, simply turn to the appropriate page and copy down the test code.
