Query: One of the Top Two Books for PMP Quick Review

For the PMP Quick Exam Review, I recommend two books: this one and the PMP Flashcard Quicklet by Paul Sanghera. I find PMP Flashcard Quicklet very self contained, while this book makes references to Rita's other books. But if you already have those books, then this book will be as good as Sanghera's.Overall, an excellent book. Highly recommended.
