<p>Here is my dilemma:</p>
<p>I just took the March SAT I and if i did not score well, I would like to retake it in June.</p>
<p>I also want to take three subject tests before the end of the year. If i don't have to take the SAT in June, I could split up my three subject tests over two testing dates, but if i do have to take the SAT again, then I must do all three subject tests in May. The problem is that I won't know my March SAT score until after the sign-up deadline for the May SAT.</p>
<p>So I was thinking of signing up for one subject test for May, and then on the actual testing date, taking one or more depending on my situation. On the CB site, it says you can take subject tests even if you haven't signed up for them - they will bill you later. Do you get billed the same amount per test, or do they charge you more?</p>
<p>Any help would be appreciated.</p>
