If I add an SAT Subject Test the Day Of...

<p>will they simply charge me an extra $9 or will I have to pay $29? I just registered for Decembers test today, figuring that I would add one or two if my scores from today were bad. </p>

<p>I just read something that said I would have to pay the whole registration fee two more times if I end up taking 3 tests. That would make it 87 instead of 47.</p>

<p>Can anyone explain this to me? Thanks.</p>

<p>Does anyone know?</p>

<p>Hm I'm not sure. But I know a lot of my friends just showed up and took another one that they didn't sign up for. They just bubbled in which test they were taking. I'm not sure if they paid for it later or what but it could've been that much if any at all.</p>

<p>I had signed up for one, but took two. They just sent me an $9 bill a few weeks afterwards.</p>
