Rita vs PMZilla....
I've read the PMBok 4th ed, and Rita's 6th ed and took her quizzes in the book. When I read just the PMBOK, I passed her tests at about 75%. Then weeks later, I start reading her book and take the quizzes and get 80% consistently. Also, her demo CD for PMFASTrack, I got 80% on 25 questions the first time. I took another sample test on the internet (5 questions) and got 100%.
So I am getting confident, UNTIL I take the PMZilla questions and consistently score 30%.
What's going on?
