I passed the PMP exam at my firt attempt on 15/Jan/2015.

I started hard study on 15/October/2014 with more than 4 hours every working day and more than 10 hours on weekend.

First of all studied PMBok and Rit prepExam on parallel, I read every process on PMBok and get the high level knowledge and then go deeply in this process on Rita book, then return back to PMbok to hiegligt the most important note and lines on it. And so go ahead for next process, untill finsh the Kowledge chapter, then start to solve quistion of Rita chapter.
