That's a fun idea. I'd worry the school might get angry at you for releasing your notes, which other students might use, but at the end of the day, does it really matter how a student learns the material? If your notes do a good job at summarizing complex information, it seems like a win for me.
Thinking about it, it would be very interesting if we had students notes throughout history. We could see what was being taught and what was being understood through the ages.
