I finally passed ! I am too excited ! The PM PrepCast is a great simulator to use to help prepare you for the exam. In fact, I thought the Prepcast questions were a lot harder than the actual exam. I listened to the podcast and did the 15 questions for each knowledge area. I read Rita three times, and took 3 simulation exams. I scored 55% on my first exam, I retook the first one and made a 70.5% and then I took a new exam and made a 67.5%. Some of you would probably think, well why did I take the PMP exam when I did not score well on the practice exam. To answer your question, I could never get the graph questions right on the Prepcast simulations and I knew that my score was actually higher than what was given to me. However, I went into the PMP exam extremely confident and calm than I was the first time and well prepared.
S/n: never fully read the PMBOK.
Good luck to everyone and do not give up!!
