Five unique 50-question sets. A 45/50 pass in either mode counts toward your level badge. There is no requirement to pass an earlier level.

Fact referenceCasual mode gives you the answer explanation after each response. Challenge mode allows 30 seconds per question and saves the full review until the end. The facts and pass mark are the same in both modes; their best scores are recorded separately.
Each fresh attempt shuffles question and option order. Resume an unfinished round to keep its existing order. Friend links reproduce one Challenge-mode order and show a self-reported score, not a verified leaderboard.
