Hi, 

i just passed the PMP exam and would like to share some light about it for future takers. 

In my case I studied like 2 months. 

I recomend reading the PMBok and Rita's. (Including apendix)

First Rita, then Pmbok and the Rita again as a minimum. And make all the tests at the end of Rita's chapters. 

In my case I never read the hole Pmbok and only read Rita's once but I had a lot of PMP experience.
