Passive Income, and Making Money as a College Student

[Trill Clinton]

Does anyone have a good idea for making money in college, that doesn't involve a part time job?

Right now, the only thing I can really do is sell my notes, and tutor. I have good grades in courses where the textbook is not used well, so this would be easy for me. But at the most, I could make maybe $100-200 a week from those, and that's being REALLY optimistic.

Are there any ways of generating some passive income that I could get a start on now (I have another 5 weeks before I'm back at school full time)?
