hi, i have decided to pursue my PMP certification based on the positive feedback from this website/forum.

As i am currently unemployed, i have given myself 1 month to complete the task.

The plan is to initially complete reading the PMBok (once) and the PMP Exam Prep, Sixth Edition: Rita’s Course in a Book for Passing the PMP Exam. Is there any disadvantage if i get the forth edition instead of the sixth edition?

Finally to do as many sample questions as possible to further prepare myself.
