Hi All ,

I have one small doubt regarding the versions of PMBOK . My understanding is the latest version of each book which must be used for PMP exam but in some of the questionair .I found the explaination that the question was from 2-3rd editions .

Please guide me which version need to follow in case of PMP prepration and most efficient way to prepare for PMP (If Any :-))

Thanks
