I passed the PMP Exam. I memorized the 42 process chart and all the top 25 calculations. However I only had a couple of questions that required calculation! So I think its more important to understand how they are used. I didn't memorize the Inputs, tools and techniques, and outputs, but focused on trying to understand them. I passed the exam on my first try! I studied for about a month and half and studied 4 to 6 times a week for 3 to 5 hours each session. It almost didn't feel like enough time toward the end. I also took multiple practice tests, but only one simulation exam the day before the real exam. The PMP Prepcast was vital in my studies. When I didn't do well on a practice test in a specific knowledge area I would go back and watch all the videos for that section (e.g. Cost, scope, etc.) and it would boost my score by 20%.
I'm so excited that now I am a PMP! I dreamed of this day for a long time!
