Query: Really helped me to pass PMP exam!

This book and the PMBOK were the core of my study materials - and I passed with >85% correct. I am recommending this book to all my colleagues as they prepare for the exam. Play the games, do the exercises and take he study questions as suggested ... it works! There were at least 2 questions that were essentially exactly from this book and most of them followed the format although they were cast in a scenario. The hints on 'what to expect' were also helpful - check the site out before exam date, bring layers to wear (or sit on), bring food and water to keep just outside the exam room so you don't go hungry or thirsty.
