I am pleased to share that I passed the PMP exam today on 26-03-2012 in my first try. I was rated proficient in all the areas except closing where I got MP.

I studied for 3 months. I used PMBOK 4th ed (3 or 4 times) and PM Prepcast (once) as the main study materials. I had ESI power prep book, slides and questions from my company but used only the slides and questions there.
