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. 

Memorize page 43 of PMbok and formulas from Rita's. find some cheat sheets as example and use the 15 minutes tutorial previous of the exam to write it down as reference. 

You can pass even if you have one BP in the exam. 

The exam feels really similar to Rita's tests, and I recomend to buy Pmzilla 200 questions as a way to learn but they are much tougher than the exam but a real way to learn. 

Practice at least 5 exams before the real one with a lot of excercises and situational questions. 

If possible do them at the same time you will take the exam and withou brakes, the 4 hours is just enough time. 

Study hard and you can do it, contact me if I can be of any help and good luck. 

By the way I am a design architect and project manager (not IT person)who decided to take the exam and I recomend it to other architects, designers or architectural project managers. The PMP has a great body of knowledge and is worth it once you understand it.
