<p>I'm registered for two subject tests in may but i may one to change one of them to a different subject test. Do i need to notify CB of the change or do I just go in there and do whatever?</p>
<p>Nope, no need to notify! You just show up and take the tests you want.</p>
<p>ok thanks!</p>
<p>except in the case for language tests that require listening</p>
<p>Exactly, if you want to be sure (cover all bases), then send an email to collegeboard as well. But there shouldn't be a problem (except with listening tests) (I did a similar thing myself, only I added an extra tests (Lit) I hadn't registered for earlier.)</p>
<p>so if u decide to take an extra test on test day, when do u pay the money</p>
<p>if you registered online then it's automatically debited from the credit card you used to pay for the earlier tests.</p>
<p>Are you sure about that? I recall my friend recieving a bill in the mail about 2 weeks after he received his scores.</p>
<p>Yup, I was billed too! (about 3 months after the test, though)</p>
