I took the PMP Exam today and passed!!! A weight has been lifted off my shoulders and I get my life back whew!I prepared for 2 1/2 months studying for 6 to 8 hours a day towards the end. I used Crosswind PMP Success BootCamp manual and Andy Crowe's "How to pass on the first try" . I did over 3000 practice questions and found that pmstudy was closest to the actual exam for me. Examcentral.com is also a good source for free questions as well as head first. PMStudy questions are based primarily on the PMBOK guide so I reviewed my incorrect answers against it. I never read the entire PMBOK guide because I found it very dry and user unfriendly. In the practice tests I got between 75 and 95 and i think they really helped me prepare for the actual exam and the practice definitely helps you prepare to take a 200 question exam which can be quite exhausting! The exam wasn't as difficult as I thought it would be which is probably because I was very very prepared. I memorized all the ITTO's and the 42 processs etc. and also all the formulas and that helped with some of the questions but it's not absolutely necessary to have the ITTO's memorized. Just wanted to share my experience with the PMP preparation and exam. Good Luck!!!!
