The core of the test is 75% ITTO, which is "Input, Tools/Technique, Output", and weirdly some of it are different between this book (HF) and PMBOK. However dull PMBOK is, because of the simple diagram at page 61 and ITTO diagram at the beginning of each chapter, it made it easier to create brain map, much more compact than this book. This book is so protracted
The rest of the test is PMBOK taken word by word.
However if you feel like I am, that PMBOK is so hard to digest, at first reading this book give a great insight. Skip the silly tests and only do the multiple choice. But PMBOK is a must.
