Query: Good book to put you to sleep

Had to buy the book for a class. The professor wrote it. The most pointless book I ever had to get. I learned absolutely nothing in this entire course. Goes to show that this is basically the capstone course for the CIS major at WMU at it was by far the most worthless class I've ever taken. The guy is completely full of himself and never makes any sense. I feel like Western Michigan wasted an entire semester of my life making me go to this guys class. His midterm was 10 questions and I knew only 2 questions. Somehow, I pulled a 97% on the exam and was absolutely shocked. Feel bad for anyone who has to purchase this book as it will more than likely put them to sleep.
