I was in a class where the required book was written by the professor. However, fortunately, the book was really fantastic and better than any other book I have seen. Plus it was like $15.

I think he wrote the book so that students didn't have to spend money on a huge textbook containing information they don't need. This book had everything you needed for the class and not much more.

I had a teacher that did the same thing...almost, he sold us the book after he had taught the class :P
