I am pleased to clear the PMP Exam on 28th Nov. in first attempt.  I would like to share some of my following insights into the preparatory process for the Exam:

1.  A sustained and continuous time frame of 3 months should be kept aside for the preparatory study, which should include 2-3 hours daily study plus longer studies on off days.

2.  Indepth study and understanding of the PMBOK are essential, since every word there is a potential question.
