I had 9 o'clock classes three days a week and had an hour commute, but I am a morning person so it didn't bother me. But as a commuter, one thing that might be bothersome is the fact that classes are spread out and you're sitting around in between. Don't get me wrong, it is nice because you have time between class to eat, chat with friends, which isn't always easy if you don't live on or near campus, and even read, study or review for your next class.
Unfortunately, it isn't a 9-5 schedule with an hour lunch built in. I agree with Lauren, you're best bet is to try to find someone how goes to that school or find the school's schedule on its Website. There might be different sections listed, but you can at least get a general idea.
