Changing Subject Test

<p>I signed up for the SAT Math II, but I am planning to take the SAT II lit. I just wanted to confirm that I can just make this change the test day. I heard that all you have to do is put in the correct test code on your form the day of the test, but I wanted to make sure this hadn't been changed. Thanks.</p>

<p>Yes, you can change it. (This question sure gets asked a lot. :))</p>
