I passed my PMP yesterday, scoring Above Target in every area!
I exclusively used PrepCast materials. I went through all podcasts at least once. I went through the formula tutorial study guide and did all those questions 3-4 times each. I did all 9 of the 4hr practice exams in the simulator, plus spent hours on end doing shorter quizzes. Much of my improvement came from reviewing questions I got wrong to really understand the detailed explanations. By the end I had both completed all 1800 questions and retested all the ones I got incorrect on the first try.
I also downloaded and went through the PMBOK 5th ed guide available on member site. I predominately focused on areas I did not understand and made sure I really grasped all tables and t&ds. I also did homemade flash cards for myself on terms, ITTOs and formulas. The last 2-3 weeks of study, I practiced writing my brain dump at least daily so I know it cold and could get it out in 10mins flat. I tried some of the questions available in free apps but did not care for them. In the end, I stuck with PrepCast materials and worked my plan. I highly recommend their tools; they served me well.
