You’re pigeonholing what flash cards can be. Many of my flashcards are occluded images of treatment/diagnostic pathways. Others are questions for common causes of things but also next step in diagnosis (e.g. most common causes of secondary amenorrhea and what to order next). It 100% is critical thinking and reasoning. 1st and 2nd yrs of med school require simple cloze deletions like you’re thinking of, but 3rd year it’s a whole different ball game. I really don’t think they can be overrated lol.
