Your questions. Your pool.
Pick the tags you're studying, and your pool fills with community-written questions. Write your own, rate others, and grind until every question retires.
Tag-Based Questions
Every question is tagged by topic. Add tags to your pool and the right questions show up automatically — no manual assembly required.
Three Strikes, Retired
Answer a question correctly three times and it's done. Your pool shrinks as you learn, so you only ever see what you haven't mastered.
Community Vetted
Anyone can write questions. New ones get tested on real users who rate them — good questions graduate, bad ones disappear.
Built for students who'd rather quiz each other than cram alone.
