My classes are NOT online, but half my work is online. It's grading about 300 Java programs every week. Doesn't take quite 10 hours most of the time but it's a pain in the ass.
And I do need to budget 9 hours of sleep... anything less than 8 on the nose and I'm REALLY groggy and want to fall asleep within 15 minutes of arriving to campus. And even that isn't always quite enough if I've been behind. I also have a hard time getting to sleep sometimes, but once I'm asleep I have a hard time waking up when I'm supposed to in the morning or daytime. I'm a big day sleeper, I'll admit it, especially when the weather is hot or raining outside all I want to do is sleep. in' Texas, man. I'm a natural-blooded night owl, though.
