What is Quably Duel?

Quably Duel is a fast, head-to-head skill challenge for students. You create a duel, pick a topic, and send the link to a friend. You both get the same set of questions and the same 60-second clock. Answer as many as you can, as fast as you can — whoever gets the most right takes the win. It's a quick way to test yourself, settle a friendly argument, or just take a study break that actually sharpens you up.
