<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>
