To get the most out of this book
This book is based on the 6th edition PMBOK Guide. The 7th is not out yet and is not expected until Summer, this will not change the exam. It will be a supplemental guide of standards.
It is best to work your way through the chapters in the order they occur when reading this book for the first time. This will give you a project management framework and allow you to focus on each section's review questions. Then, after completing each chapter's assessments, you can go back and review what you missed before moving on to other chapters. After completing the final exam, you can then go back and review those areas where your knowledge is lacking. Study what you don't know, not what you do! Good luck!
