Negative Positive
Title: Out of date.
Review: Unless you would like to spend time studying for a version of the PMP exam that PMI no longer administers, stay away from this book (Practice Questions). I will verify what a few others have stated concerning the poor quality of the questions and the ironically spotty quality control in the product, but most relevant to my mind is that it deals with (some) topics that are no longer dealt with in the 3rd edition of the PMBOK. There are much better practice question options out there, but you may have to pay a little more for them.
Is the review positive or negative?
