Any university where the "teaching" involves just answering questions in a book you can just buy is a scam. I can get that for, at most, the cost of the book on my own. I don't need to pay 4-6 figures for that as well as still buying the book. I don't think I ever was assigned to answer questions from a published textbook for credit at university. If we had such question-based assignments, the questions were written by the lecturer to fit the course material. We were recommended to get certain books, but they were never required to complete the course.
