<p>Hi all! I posted this in the SAT thread, but maybe you guys in the HSL can help me. Anyway, I decided that I want to take three subject tests in June instead of two. On the CB website, it says I can do this on test day. But when I sign in and try to change any information about my tests, it requires a fee. Can someone help me? Can I add another test on test day? If so, how can I do this? And, is it free? Thanks!</p>
<p>You have to pay a fee. Whether you pay it now, or after the test is up to you.</p>
