I was preparing from Rita Mulcahy's book, but the book was confusing enough, especially the Main Chart to remember.
Then I started PMBOK guide and spent almost 2 weeks only for sequence, Inputs - T&T - Outputs of all activities.
Then I used PMPrepcast simulator and completed all 9 exams including Input Output exam. I failed in First 2-3 simulator exams, but after completing Input Outputs with 99%, I cleared all remaining simulator exams with 85% and above. At that point, I started feeling confident.
I had already paid the exam fee and completed application before I purchased PM Prepcast. As a sidenote, I never saw the videos since I had already completed Rita Mulcahy's book.
Finally, on the exam day, I was very confident and cleared the exam 20 mins in advance, which was not possible without Prepcast simulator.
