"There is no such thing as a free lunch." That rule is busted when the Professor/Lecturer uses his own book as your course text book. You are often forced to buy his text book.
Never question the Professor/Lecturer when he/she makes a mistake. He/she decides whether or not you pass or fail the course. It would be a terrible shame to repeat a class and be forced to buy the next edition of his text book for next semester. Repeating a college class is Groundhog Day.
