<p>Can I change the subject test on test day. I signed up for Math 1, Biology and physics. After taking some practice tests I decided I am in over my head, can I just take a lit test on test day without changing it on collegeboard.com</p>
<p>yea you just show up on the day of the test and only take the test you want to take and leave... it doesn't matter what you signed up for, but you will not be refunded the money for the other 2 tests that you already paid for</p>
