<p>I took SAT II chemistry and Math II on June 5. But I only registered for chemistry. My math wasn't that good. I know that collegeboard will send me sat fee online soon. Do I have to pay for it? I am wondering that if I don't pay for it , will they cancel my math score? Will it affect my chemistry score?</p>
<p>Hm, I think they’ll cancel BOTH scores if you don’t pay (because if they cancel one score, they cancel all scores taken on that day). If I were you, I’d just pay the cash, and retake the test if I did really badly on it and knew I could do better. By the way, I took the same! Good luck and cheers.</p>
