I passed! Wahoo!!!
My strategy was to read Head First PMP over the course of a few months, completing exercises and quizzes as I went. Then, 6 weeks before my exam, I purchased a PrepCast Exam Simulator subscription. I completed two full exams and a few learning quizzes to help me identify and correct knowledge gaps.
I took the exam last week and passed "Above Target." Wahoo! I don't see where people are getting their % pass rate; that does not appear on my documentation.
Start to Finish, I studied ~3 hours a week for three months and 5-6 hours per week for the last 6 weeks.
Good luck to everyone studying for their exam!!
