Hello,
I'm sorry to hear that you did not pass on your two attempts. It is frustrating, but it happens. And it is good to see that you have a positive attitude and that you are willing to tackle this and get ", PMP" behind your name.
My number one recommendation for you is this: Read my article about how to recover from a failed exam
www.project-management-prepcast.com/failed-pmp-exam
and look in particular at tip number 4. You have studied a lot already and you probably know your stuff. But it seems that you may not be able to translate your knowledge into identifying the correct answer.
The article contains all my tips and lessons learned.
You can do this!
