This is an excellent resource. There are a lot of tips, exercises and call-outs in each section. I particularly love the first section that provides a thorough plan for how to prepare for the exam. (Step one is the first read through of this book.) I really wish I had found this a couple years ago instead of trying to slog through the (unreadable) PMBOK reference guide. This has all of the essential elements but also uses a narrative format and includes examples throughout.
