Got the full Prepcast package with the formulas guide and the Exam Simulator. Which was a more affordable option for me, and yielded to be the best option by far.
Cornelius is the smoothest teacher i ever listened to, and he is very funny and his humour is engaging rather than distracting. It felt like I knew him at the end of the PrepCast.
I watched all the videos, at home, in the car while commuting, even during vacations. Studied for at least 2 hours a day during weekdays and 8 hours a day during weekends and holidays. I never spent more than 3 days without studying so i can keep my PMI mindset on. I read each chapter of the PMBOK as i watched is relative videos and at the end of the Prepcast I screened the PMBOK one last time before the exam.
I did all the questions in the Exam simulator, mostly with every chapter, and at the last week before the exam I did every day one full exam.
Only stopped studying the last day before the exam, and that was enough for me to get Above Target in all of the Process Groups in my actual exam.
I highly recommend the PrepCast!
