I'd like to hear about your experiences and if you have any practice test sites you would recommend. I have thus far used O'Rielly's Headfirst PMP guide which is a fun workbook but tends to get highly detailed, maybe overly so and I'm using "The PMP Exam: How to pass on your first try 4th ed" which seems more appropriately high level. So far I've memorized the 9 knowledge areas, the 5 process groups and all 42 processes. Now I'm working on memorizing the inputs, tools and outputs of each. I feel like I'm memorizing the Federal Tax Code. Am I doing too much? Not enough? Focusing on the wrong stuff? Guide me oh gurus of the web.
