How Percentyl practice works
Every question in the arena is a genuine previous-year question (PYQ), correctly keyed to the official answer — Percentyl never serves AI-generated filler in ranked play. You answer against a timer and see an explanation immediately, so a practice session doubles as revision. As you play, an Elo-style rating updates and maps to a live global percentile, climbing from Rookie up to the Top 0.001%. The rating is accuracy-gated, which means a careless run can never inflate it and the ladder stays honest. When you are signed in, scoring is server-authoritative and protected by anti-cheat checks.
