Can some of you recent test takers confirm if Point of Total Assumption (PTA) concept is asked in the exam? I don't find any reference to it in the PMBOK v4, while Rita explains it on Page-438, so not sure about it being "in scope" or "out of scope"? 

Are all the questions out there asking about PTA outdated and based off of PMBOK v3? Because I really have no time to remember one more concept as I still have to start taking practice tests, with very little time at hand, I would like to make the best use of it.

Thanks
