A mini quiz of just five questions, once a day. They are drawn from four titles — Math II/B/C, theoretical chemistry, history inquiry and the exam quest — so it works as a quick review.
The set is decided by the date, so everyone gets the same five questions on the same day. Each day you take it adds to your streak, and you can share the result as a 🟩🟥 grid.
No sign-up is required and your records stay on your own device. The questions themselves are in Japanese.
