Again, no. Key words are ambiguous and lead to an unstructured, almost frantically disorganized, style of study. That being said, a comprehensive array of key word topics are covered within the M5 question bank, its just that the questions weren’t written specific for each key word (if that makes sense). Don’t waste money on key word study material, when OpenAnesthesia.org is free! Our suggestion is to study the content outline for the written exam you are taking provided by the ABA.
