I have passed PMP exam on 29.06.2021. I have read PMBOK Guide and APG that follows. I have used for preparation Rita's book, but I have to admit that without PrepCast I would probably not succeed, because even being able to embed the traditional project management way of thinking with agile, I for sure could not succeed this for hybrid subject questions, in less than 1.3 minutes is available for each question without training. PrePcast has lots of questions that improves your thinking speed. I used it, review my mistakes and after, select questions only from the wrong answer to understand and improve.
Even not only one question was not the same in the real exam, my preparation helped me for 3 AT, finishing 11 minutes before ending time.
