<p>I registered for the November Math I and Physics subject test. Is it possible to edit my registration and to add another subject test (Math II) ? I mean...I changed my mind and I also want to try Math II ...is it possible to add it for November? if yes, how?</p>
<p>As far as I know, you can ask them for Maths II there in the centre itself. You will be charged later on for it.</p>
<p>I’ve never tried, but according to College Board, you can ask at the test center on the day to add (or remove) tests, with the exception of the listening tests. If you remove tests, you don’t get any of your money back. If you add tests, you are charged later on for it.</p>
