<p>i registered for the physics sat ii already for this saturday, but i want to add another one, but registration is already over. is there any way that i can go on the day of the test and sign up/pay for my second one since i've already reverved my seat for the first one?</p>
<p>yes you can...the proctor will explain everything that deals with this when she/he reads the directions. They will bill you for any additional exams you take.</p>
<p>okay thanks !</p>
