PMP Project Management Professional Exam Study Guide: 2021 Exam Update (Sybex Study Guide) Paperback – Import, 16 October 2020

The good part - better explanations than the BORING PMBOK. Bit more interesting to read.Bad part - no questions in between the chapters... not the ideal way to grasp concepts. New prep book by PMI does this much better.Secondly, this book is NOT exactly according to 2021 ECO. It still groups knowledge areas into processes (Planning, Initiating etc) that PMI has completely removed.
