Yes, in USA you generally have to buy the book. In fact, because our teachers tend to get paid so little here, sometimes they will write a book, and then require the students buy that book to learn out of for the class. While this kind of sucks, I also understand them doing it because they get paid so poorly. The one thing I really hated though were the times we were required to buy a book and then barely used it. Which was often.
