Hello Nikolay... I also fail my fist attempt. 4 weeks later - I took the test again and passed. If I can pass.. trust me...anyone can pass.
I intensified my practice and studying. Used Rita Mulcahy's PMP Book, Took 4 PMStudy Exams (pass them all), and also,
took booster courses at my local pmi (I wasn't impressed with that - I was way to prepared), I also took practice tests from a site call mypmp.ie.. theses were pretty good. I study ITTOs not by memorizing them, but rather where in the process I was... try that... Good Luck!!
Regards.
