I passed PMP yesterday. Thanks to the PMZILLA forums for providing lot of useful information especially LL. I started studying for PMP March end and studied for 2 months with great dedication. 2hours daily and 6-8 hours on weekend. Books referred - Rita Mulcahy and Andy Crowe, not to metion PMBOK. Took lot of full length sample online tests. I also paid pmperfect for there online practice tests, they have some good set of questions very similar to actual exams.
