I have class at 8:30 in the morning, and I work full time, usually until 10:30 or 11:30. It takes me an hour to get home, so I don't get to bed until sometime between 12:00 and 1:00. I have to get up around 6:30 or so, so if all goes well and I get to sleep right away, I can get up to 6 hours of sleep.
