To those aspiring PMP's,
Make to sure to develop a regimented study plan. I studied for nine months and read the PMBOK two times. Also purchased the Podcasts, Rita Mulcahy's book, and a situational question test book by Ginger Levin. Please do not underestimate exam content. Don't try to memorize ITTO's, yet understand the overall process related to each, so you can make an informed decision. Understand the formula's and memorize when to apply certain formulas to particular situations. Good luck!
