Title: Good, but don't use as your only reference...
Review: Great book for summary of the CPM module knowledge base but there are flatly exam topics the book does not cover. I passed the 4 CPM Modules on the first try using this reference and the 2 available practice exams, Diagnostic Kits as they are called, from ISM (they are relatively affordable). The latter was exceptionally valuable in giving me a taste of the exam questions and the answers detail in the kits helped fill in several loose and missed topics in the The Purchasing and Supply Manager's Guide To The C.P.M. Exam. Good Luck.
