Thanks God i passed PMP exam at last. Study plan was i studied first Rita once. Then listen to all the lectures of PM PrepCast whenever i was free, most while driving and free time at home. In third session i studied Rita twice with ITTOS from PMBOK5 at the start of chapters.
After that i repeated ITTOS almost every day. For confusing terms i consult PM PrepCast lectures and internet. In the last week i spent most of the time solving questions.
