Lukasz,
Here are my answers... however... you are not going to like them, because PMI does not officially give any of the details you are asking about:
1. Please refer to The PMP Exam Content Outline
www.pm-prepcast.com/pmpoutline
where you can see on page 2 how the percentages are set across all 3 domains. There is no mapping against the 10 knowledge areas, because those are part of the PMBOK Guide and the PMP exam is NOT a test of the PMBOK Guide.
2. PMI does not make any statements other than the percentages per domain. Again, there is no cross referencing against the Knowledge Areas possible because that is NOT what the PMP exam tests.
3. PMI has an official list of PMP exam reference materials. You can find them here
www.pmi.org/certifications/project-manag...pmp-exam-preparation
(scroll down). However, we cannot say which book they use for the domain you ask.
4. Sorry, but your assumption is wrong. The only correct statement is that in our exam simulator we have set 70% as the passing score and PMI does not officially say what their passing score is.
5. There is no such rule. What PMI does say is that NI, BT and AT are here for general guidance and that the totality of the score counts. And that's pretty much what we are seeing... there have been students with "bad" results in two domains, but with an excellent result in the third domain, so they still passed, since it is the total score of all questions that determines if you have an overall pass or fail.
I'm really sorry that I have to give you such "vague" answers, but the truth is simply that really only PMI knows the answers, and they are silent.
Until Next Time,
