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.
