<p>if i register for sat2 math 2c and chemistry now, and when it is the testing day in nov. can i change chem to bio? if this is possible, will it cost money?</p>
<p>I'm curious about this as well...I am taking the subject tests in October (so...two weeks), but can I change them before then? I once read somewhere that you can change the day of the test but that might be completely wrong.</p>
<p>Yes you can change which test you take.</p>
<p>Yes you can add a test.</p>
<p>"SAT Subject Tests
If you are only taking one or two Subject Tests, you may leave the test center after your final test is finished.
You may work on only one test during each testing hour. You will get a short break at the end of each hour of testing time.
You can take up to three Subject Tests on one test date.
You can change your mind on test day about which Subject Test you want to take. You may substitute a Subject Test (other than a listening test), or add Subject Tests (other than a listening test) on test day."</p>
<p>My son changed his mind on the SAT2 last June. All of the tests are in the booklet you are given, apparently. It's no problem to switch once you are there-- I think the foreign language with listening is the only type that would be a problem.</p>
<p>I registered for three subject tests this Oct but now I just really want to take one instead of three. Is that still all right ? What am I supposed to do now(like tell the proctors or notify CB, etc) ? ^^</p>
<p>Bump, I was wondering about that too.</p>
<p>UPDATE: Never mind, I found the answer.</p>
<p>Summary: just take the tests you want to take on the test day.</p>
