TOPIC: Is Process Groups: A Practice Guide a replacement for PMBOK 6th Ed?

I understand that the PMBOK 6th Edition content will be included on the PMP exam, but where am I supposed to access this content now that the 6th Edition is no longer available? Do any of the following resources act as a replacement for the 6th edition (for the purposes of studying for the PMP exam)
1. Process Groups: A Practice Guide published by PMI
2. This article by PM Prepcast www.project-management-prepcast.com/pmbo...d-pmi-process-groups

I've read that Standards+ was a replacement, but was this only before Process Group: A Practice Guide was released? I find Standards+ really confusing to navigate.

I just want to know what to study!

Thank you all in advance!
