Watching and listening to The PM PrepCast™ with or without additional study is no guarantee you will pass the exam.
Recommendation
We recommend you create your own study plan, read A Guide to the Project Management Body of Knowledge (PMBOK® Guide) at least twice, purchase a PMP® Exam preparation book, and attempt to answer as many sample questions and complete as many four-hour tests as possible in addition to listening to The PM PrepCast™. Studying for the PMP® exam is a serious endeavor and requires personal dedication.
