Uhm...but credit hours aren't the same as hours in class? I mean...I can't imagine that you have to sit at university for 72 hours a week? *g*
I for one, am just talking of "real" hours - the time I have to spend at university, sitting in courses and so on.
No, credit hours aren't hours spent in class, credit hours are just how many credits the class counts towards your degree. Here we don't count how many hours are spent in class per week, all the college cares about is that you pass your classes, and once you pass, however many credits your class is worth is put towards your degree.
