The course
The exam
48 suit combinations, each with a target. Play each one; the first card that is not the best card is your answer, and there is no second go at a question. Nothing is timed.
Your answers are kept as you go, so you can stop and come back. Take it as many times as you like — only your best score is remembered.
You are not signed in, so this run is not saved — a reload starts it over, and no score is kept.
