I passed the test on the first attempt on September 27. The exam is difficult (especially since English is my second language). I advise to take "language support" when registering for the exam. I spent 3 months for exam preparation. I read PMBOK 3 times. Rita Mulkahi - 2 times, but it was a long time ago. I made an abstract from her materials and did not read it any more - this book is more for beginners than for those who have experience.
A huge role in the preparation was played by the materials and tests of PM Prep Cast (OSP International). Theory materials - clear and compact. When you start simulator you understand your gaps in theory.
I recommend that everyone completely look through all the questions of the simulator after passing the test and not be limited to just the wrong ones. OSP has a very detailed description of the answers and you actually go through the theory one more time. Their online help option is very interesting and helpful . I used it and got a professional answer. I recommend, since the PMBOK itself does not prescribe certain issues clearly.
Gook luck to everybody and THANKS to the "OSP International" and it's team for materials and support!
