My school defined a full time student as 15 credits per semester, which would work out to 5 classes most of the time (some you get an extra credit for a lab). THe expectation being that you will probably spend 1-2 hours outside of class for each our in class. That works out to 30-45 hours a week, so pretty much full time hours. They also wouldn't let you take more than 20 credits in a semester without written permission as it is too likely you will fold under the pressure. I did 18 credits once and it was a pretty horrible experience.
