<p>Hey I am signing up for Math II and Math I in June. However, I am considering taking bio also, if I get below a 770 (took it may 1st). I know that there is this thing where you can take whichever test you want on test day? Some of my friends did something like that. Can I sign up for Math I and Math II and then do Bio too? Would they bill me for the extra test at some point? Or is this not allowed..</p>
<p>You can take as many tests in whatever subjects you want on test day (three maximum, though). You will be charged for additional tests and will not receive refunds for tests not taken that were signed up for.</p>
<p>Thanks. U da man</p>
