<p>I signed up for Math II but am thinking of changing it to US history. If i do will i need to contact college board? When i looked at their site it said i can substitute another test on the the day of the test, but i don't get what it means. So on the day of the test, instead of taking MAth II can i just take US history without contacting college board?</p>
<p>Ya it cost like 20 something extra.</p>
<p>NO!
You can change it when you get to your test center. You can change anything as long as it's not a listening test, because then they'd have to order CD's. Also, if Math II is the only test you were going to take both, you can add a test at the test center and they'll bill you later.</p>
<p>what if i only wanted to take the US history instead of the math on the day of the test? do i have to tell the proctor or CB anything, or do i just do it?</p>
<p>nevermind just read another post. thanks for the help</p>
