on the first day of my operating systems class, our teacher held up the course text book and forbade any of us from buying it. anyone who purchased the book would have an unfair advantage in the class and likely get an A, which makes it discrimination. he told us the textbook had the answer to every question he'll ever ask on a test, and he considered anyone who read that book to be cheating.
It's very likely the answers to the questions in your book are in the book itself if you read the chapters.
