Few tips for PMP hopefuls (I might make a thread on PMP studying):
1) Buy the Rita book; work thru it once cover to cover and work the practice problems at the end of each section as a simulated exam (don't use the book as a reference). Take a break from the book (week or so) and then work thru it again. You should have improved a lot.
2) Buy access to www.pmstudy.com to work problems. These were very similar to the actual exam.
3) Take the Oliver Lehmann exam (75 questions) in a simulated situation:
http://www.oliverlehmann.com/pmp-self-test/75-free-questions.htm. Consider his other questions (at cost) if you need more practice. His problems are tough but are good (kinda like Lindbugh).
4) Make flash cards of all the terms used throughout the Rita book (example: parametric estimate vs analogous estimate). Memorize all the terms and different mini-processes (example: steps required for Risk management). I carried the flash cards with me everywhere and practiced before bed. By the exam I memorized over 100 flash cards; this helped A LOT of the exam. I wish I still had them so I could make an iPhone app!
You should be OK if you do all this.
I also recommend joining PMI to get the exam fee discount.
Cupojoe's advice (Pem-Bob) is very good. You need to break bad habits you have and need to really think the way PMI wants you to think about project management. You will appreciate the "right way" to manage a project during studying and if you can understand the whole big picture of project management thru the different phases then you are ready to take the exam.
