Good material for preparation to pass CompTIA Project certification exam. Note, that material is for exam PK0-003, which is out of circulation as of 2017 and current version stands at PK0-004.
As my personal experience shows, it is actually quite possible to prepare and pass PK0-004 with only this book as learning material, but I would advice against it. Some topics of current exam are not covered at all (Agile project management methodologies), some only in part.
Over all material is delivered competently and with sufficient examples. Lacking is graphical representation of all project management documentation, structure (logical) of processes and documents, but all that can be easily found online.
Over all, with good supporting methodologies for learning ("pomodoro" technique, internalization, recall) this book will help to get ready for exam in 2 - 3 weeks. As mentioned, look for new edition.
