What you can do is go on line get the application, print it, then fax it with your credit card info.
I do know that QAI is working with a Jr. College in FL to build an electronic version of the test and that one of the hopes is that there may, one day be, an ol-line version of the exam. I think that's just in the early "what if" stages though.
The QAI institute is actually beginning to restrict the number of exam sittings it offers right now. They have just published their new list of exam sites and dates. If you take a peek at http://www.softwarecertifications.com/
you might find one nearby.
