From the grace of God and support from forums such as this I passed. I only think it be fair to let you know how I did it as I learned from many others on here. I read the PMBOK guide once, Headfirst Lab once and Rita once. Both Headfirst and Rita brought it all together. Reading PMBOK alone won't help. Like many others I did several simulation tests, really never getting more than a 75 on any. The one bit of advice I can give is truly understand the processes, their purpose and when they happen. Many of the questions will make sense.
