TOPIC: How deep do I need to go with EEFs and OPAs?

I’ve been reviewing PMBOK and keep running into EEFs and OPAs. I get the basic idea, but how detailed do I need to be for the exam? Are they mostly context clues or do they show up in tricky questions?

Just trying to avoid overstudying the wrong stuff.

Hi Christopher,
For the exam you just need to know which is which - OPAs = what you can use, EEFs = what you must adapt to.
