Today I passed my PMP exam and I feel like a weight has been lifted.  I want to thank God, my family and this forum for all of the help and support.  I had a lot of situational questions and the answer choices were not very straight forward.  So I would suggest that you fully understand the purpose of the ITTO.

Here are a few of my study tips

Read Headfirst PMP and PMBOK

practiced dumping the formulas and Pg43 from the PMBOK several times per day.

Took several different exam simulators such as PM study, Exam central, Headfirst, Techfaq360
