I passed my PMP exam today. I could not go on reading Endless lists from Rita Mulcahy book and then switched to Headfirst. This book does not promote rote memorizing, but more practicing in real scenarios. It is not a concise book. There are some chapters that probably need more information, such as Procurement management. The only con is they have not updated the book for recent exam changes. To be fair, I did practice Rita's exam questions.
