<p>If you sign up for two tests, and then you decide you want to take more or less, at what point do you have to make the decision? Can you take one test and then decide if you want to continue with another, or do you have to say how many you are taking when you first arrive?</p>
<p>You can make the decision on test day.</p>
<p>do you need to tell the proctors if you want to change it, or do you just take an extra test...is it complicated at all? I'm wondering for tomorrow what the procedure is</p>
