Pick a deck, then choose how to play: a fixed set of cards, a time box, or endless. Quick-fire against the clock, one card at a time — no account needed, and this never uses your one free 40-question exam.
Enter the code your instructor shared to run their locked assignment.
Three ways in. Expected times use your seconds-per-card setting.
Steady tiers are estimated from item features — not calibrated psychometrics. Adaptive starts at medium and gets harder when you answer right, easier when you miss.
Difficulty tiers are still being generated — steady tiers play mixed for now. Adaptive still steps.
A fixed set of cards, then a full run report.
As many cards as you can before the clock runs out. Finish the card you're on when time hits zero.
No target — a checkpoint with your stats every 10 cards. Stop whenever you like.
