Recall-style prompts: “when do you use X?”, “explain Y.” Think it through first, then reveal. No multiple choice to lean on.
There are no options to eliminate: you answer from memory, then grade yourself against the summary and the details. Free recall is harder than recognition and it's closer to what an interview actually asks for. Cards are drawn with spaced repetition, so the ones you miss come back sooner and the ones you know back off. Progress is kept in your browser.
