I know 6 people that has their PMP and they all passed the first time. I don't know what I did wrong, I studied, studied and then studied more. I even studied on my vacation in Cuba.

How does anyone pass this exam? it's so ambigious and opioniated.

What did I do wrong?

I used Andy Crowe, Rita and PM Study.

Andy Crowe simulation exams seemed too easy.

Rita was  was good. I Should have spent more time with hers.

What's a good rule of thumb for waiting and taking the exam again?
