I'll admit that I've never skipped a class in my life. Not because I'm a nerd, but because the implications of skipping a class are too costly, literally. Have you ever thought of how much a class is worth per day? If you went to a private school it'll be around $70 per hour of class. ($70 an hour is equivalent to a salary of $145,600 a year by the way) This is why Higher Education Institutions make such a great business. You pay in advance for a service in education, but there's no refunds when you skip. It would be nice if you could pay per day. That way it wouldn't matter economically if you miss the class or not for any reason. If you miss a class because your sick and have to go to the doctor, you're basically paying for the class you missed and for the doctors visit. Shouldn't you be able to get a note for a refund? Anyway, being sick is one thing, but think about what you can do with that money next time you consciously decide to skip.
