Do I have to charge 21$

<p>...FOr changing subject on SAT 2? Someone told me that 4 example, if you register for SAT II Math IIC, SAT II Lit, SAT II His, on the test date, you can take whatever 3 tests you want. You just have to indicate the subject in your answer sheet. you dont lose any fee</p>

<p>You can change subjects on test day without paying any fee. All of the tests come in one big book that everyone gets, so it isn't an issue.</p>
