I passed my PMP exam on May 8th . I Read Rita'book three times,and I
Did the prep cast sample questions , this was the key to pass if you do an average of 80% on at least 6 of the 200 question , you are ready to go.
But also ITTO need a little attention on these questions. Try to summarize it on your own way.
I used the PMBOK book as a reference reading the charts and the ITTOs.
Solve as many sample questions as you can. Prep Cast sample questions was sufficient and do the work , they are almost similar.
Thank you PREP cast and for all who support me passing the exam
Good luck for all.
