<p>Hello!</p>
<p>I registered SAT II Math II test on January 25, and I want to add one more subject test, physics.</p>
<p>According to the College Board website, I can add subject test on the test date. </p>
<p>Question: 1. Should I pay by credit card or cash when adding to test?
2. College Board says when there is no material, i am not able to add test. This thing actually happen?
3. When should I ask them to add test?
4. Can I just change through calling to College Board?</p>
<p>Thank you!</p>
