My sleep schedule has nothing to do with class, sadly. If I don't feel like going to class, I don't so I usually get between 10 hours of sleep, 8 if I go to class. I'll probably be napping soon even though it's not even 6pm, because I got up at 8am, instead of my usual noon, but that's because I went to bed early last night, because for the last week I've been going to bed at 10am and getting up at 6pm. So, I like to get as much as possible, but I usually don't get as much as I want.
