I found this forum about a month before and would like to post my lesson learnt for the PMP exam too. I passed PMP exam on 29th July with MP in all process group.
* I started reading books around 3-4 months before and started with Rita and then moved to Andy. I also read PMBOK 2 times. I would recommend people to read Andy, its very simple and easy to understand.
* While I was reading books, I kept a diary with me and wrote all important points that I felt was necessary and important. I could make notes of around 100 pages. This could be one key for my success too, as I just referred this note for the last 10-15 days.
* I tried the free exam from PMStudy, Sordo, Oliver E Lehman, Head First, Effective PMC, Simplilearn, Edwel. I secured around 60-70% an average in all. Never above 72% in any exam.
* I purchased Pmpforsure tests 10 days before the exam and I found them tough and had issues in understanding their language. Upon further enquiry from them I realize that they have used PMBOK line extract heavily in the questions and explanations and hence their grammar and language is not that easy and friendly to grasp when you start up. However, I found the questions to be the best and most challenging as I went forward with their tests.
* I would recommend PMStudy, Oliver and Pmpforsure tests. No one was closer to the actual PMP exam, but would help you in judging your preparations.
* PMP exam is not that easy, most of the questions are situations and its very hard to make out what exactly the question is referring too. 4 hours of test duration is another challange.
* You will find PMP exam has lot many questions on Risk, Quality and Procurements. Not more than 15 questions were on numerical.

I am happy today, I could crack the PMP exam. I would wish good luck to all people preparing for the PMP exam with the new changes that's applicable from today.
