As the owner of PM Higher Learning, Alexander McDuffie, PMP has seen the struggles of people passing the PMP exam. He said, there is very limited material out there that is like the real PMP exam. That is when Alexander created this book. He wanted questions as close as possible to the real project management professional exam. In this book you get 10 quizzes that are very realistic assessment to prepare you for the test. Each question is derived from the Project Management Body of Knowledge (PMBOK) 5th edition book. Alexander McDuffie's research has made this book very close to the real exam questions. After you finish this book, I invite you to go to PMHigherLearning.com where you will find several mock exams that will help you master your skills at project management. These exams are timed and show you what you score in each section, just like the real one. If you go to PM Higher Learning YouTube channel, there are weekly videos posted to help you answer questions or give guidance to those taking the exam.
