As posted earlier, I cleared PMP on 13th May in first attempt with 2P & 3MPs. Here are my lessons learned:

Study pattern:

I took training little more than 3 years back but for various reasons could not continue further study/preparation. Only in last dec (2012), I decided to complete the certification, so went for a refresher course (1 weekend) and started studying. Initially, read PMBOK in detail (every bit of it), underlined important points etc.
