That's one of the things I really, really love about Maryland's curriculum - early class to get you going in the morning, done by noon, and then plenty of time to work out. I can't imagine going to a school where you'd be in class 9-5 and then having time to exercise. I'd be exhausted! Either that, or I'd skip class and then feel guilty (I'm the kind of student who has to go to class to learn, but I can only focus for a couple of hours at a time!)
When I was in college/grad school, I always tried to schedule my classes this way...I always opted for the 8- or 9am classes, but I was usually done at a decent hour, or, if I had an afternoon/evening class, I had a long chunk of the day free in between.
You do tae kwon do? That's awesome. I tried to get into that when I lived in Seattle, but I only took lessons for a few months. It was so intimidating because it was a fairly established facility and there were very few beginners. Most folks there were advanced or blackbelts, and always felt out-of-place during class. Also, one of my instructors was really weird. But I liked all of the self-defense stuff that we were taught. How long did you take lessons for, and how far did you progress?
