<p>Can you add an SAT Subject test the day of when you're already signed up for another one? If so, how? Do I talk to the proctor?</p>
<p>Yup, they’ll ask you to stay if you have a second test…you just stay. There’s a late fee that’s going to be charged though, 20 bucks, i believe. If you plan on doing that, good luck! <em>YOU MUST ALREADY BE SIGNED UP FOR ONE</em></p>
<p>Yep, I’m already signed up to take Math II, but I want to take chem as well Thanks so much!</p>
<p>Yup. Just stay for the extra test and fill in the bubble saying you will be taking the extra test and you are good. CB will charge you for the extra test once scores are processed.</p>
