<p>I recently got an e-mail from College Board that was titled URGENT - SAT INVOICE</p>
<p>From what I understand from the e-mail, I have to pay a balance of 16 dollars, I think it's because I added a subject test when I registered for only two. But I thought that it would automatically bill the credit card I registered with. Currently, it's saying that my payment options are by fax, telephone, and there was a third option, and they say that I should pay immediately or my account will be on hold. What does my account being on hold mean? If I don't pay fast enough, but pay later, will my account not be on hold anymore? </p>
<p>The thing is, my parents are both out of the country at the moment, my mom will come back in a week, so I don't think I can do anything until then. I've send them the e-mail, hoping that they can pay from where they are. Is this a big problem? or am I over-worrying?</p>
