This book was the only resource I used to study for the PMP exam, and I passed it on my first attempt. I did the practice exams at the end of each chapter and was concerned that I wasn't doing well enough on them to indicated that I'd be able to pass the real exam. However, it turns out the book got me "over-prepared", and I felt that the real exam was relatively easy compared to the book's exams. Maybe it was just in the way some things were worded, or maybe the author truly meant to make the practice exams tough just to ensure the reader is ready. But either way, it worked.
