My question is related to the learning materials to succeed the PMI-PBA exam...
While passing through exam simultations, I am surprised to encounter so many questions who are not related in the PMI-PBA official materials.
I tried different simulation sources and the types of questions seems to be so broad, as well as, sometimes, much more difficult than the simulation provided by your services.
For instance the book "PMI-PBA exam practice test and study guide" Offers highly tricky questions...
How close to the reality the questions you are providing are? Is it really enough?
Shall we read and practice our knowledges with all the following references?

I am feeling a bit in a scope creep right now, I would deeply appreciate if you could shed light on this matter

Best regards
