I recommend that you do it in parallel: Read your books & watch The PM PrepCast more or less at the same time. (Usually I recommend that you focus on each chapter of the PMBOK Guide for 1 week of study).
Some people like to first watch the videos and then read the book, some do it the other way around. But most people agree that doing it in parallel is the best way for intensive study.
I have purchased the pmprepcast and have loved the way it is all presented. I am really liking to hear and watch all the lessons. What should be the approach of my study, should i read the book first each lesson and then listen to the podcast or should i finish reading and then listen to the podcast?
