My study group is split. Half of us think that with the big 2026 shift from Knowledge Areas to Performance Domains, all our current books (PMBOK 6/7, Rita, etc.) are basically obsolete. The other half thinks the core principles and mindset are the same, so the old materials are still 80% valid.
For those who have analyzed the new Exam Content Outline closely: are we wasting our time drilling ITTOs from the old Process Groups? Or should we keep using our 2024 study plans until the new simulators and books drop next year?
