<p>If I signed up for a Math IIC test for the november 5th SAT, can I add a chemistry for the same day? Because I just realized one of the schools I want to apply to requires three, so I need to take another one in order to fulfil the requirements. (I took one before I already)</p>
<p>When you go to the test center, take the two tests (Math IIC and Chem). The CB will send you a bill for whatever the fee is for one subject test</p>
