These 3 PMP portals were the keys to my success. Yesterday I got my results and that day became the best day of my life. It was my first attempt.

Pmzilla.com - I studied with a friend and our favorite guide was Najesh Nair Notes (http://www.pmzilla.com/comprehensive-pmp-notes). Some of the good points are not found in the PMBOK and understanding of those helped a lot. You must review this study material after you take the tests and you will begin to see how everything comes together.
