<p>Uhm, I registered to take 3 subject tests on May 5, but I only want to take two. Can I do that without canceling the scores?</p>
<p>I'm interested in this as well, not this year but eventually.</p>
<p>Yes. My son did this before, signed up for two and only took one. Your score report will only show the test that you took. You can also add a test on the testing day (except for a listening test) or substitute a test (i.e. take math instead of history). However, if you take all three tests, you can't cancel only one, you would have to cancel all 3.</p>
