Is the PMBOK Guide Part II -- The Standard for Project Management -- necessary to read for the PMP exam? At a glance, it seems to have the same information, structured by process groups rather than by knowledge areas. But it is only about 100 pages compared to the 500+ of Part I. It seems that it would be good to read as a review of material, but I am afraid that it omits a lot of info from Part I that I should know, and may lead me to overlook that information when reviewing for the exam.
