Need help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

<p>I registered for SAT Subject tests Chemistry and Physics on May 4. I want to add another subject test Math Level 2 and I can't add! Collegeboard says I can finalize my test choices on the test day. So my question is that can i take all Physics, Chemistry, and Math 2 on the same day??</p>

<p>You can take up to three subject tests on one day, so yes…</p>
