Important Question about registering for SAT 2's

<p>Is there a fee per exam or just a fee which lets you take as many as 3 exams a day.</p>

<p>I plan on taking the Sat Subject Test in Chemistry and Math II but i was wondering, if i pay the same if i take 2 compared to 3 exams, why not just take another Sat. </p>

<p>Question:
Math, Chemistry, and Biology SAT Subject tests cost= Math and Chemistry Subject Test ???</p>

<p>no you have to pay a base fee (registration fee) of $20 and each test you decide to take you add $9</p>
