"This Month" resets on the 1st of every month · "This Week" resets every Sunday — everyone starts fresh.
How the PyDebug leaderboard works
Every solved practice problem earns XP: harder bugs pay more, and finishing the daily challenge keeps your streak alive so the weekly board stays competitive. The all-time table ranks learners by total XP, then by problems solved; the month and week tables reset on the 1st and on Sundays, so a new learner can reach the top of a fresh board within days of starting.
Your personal rank, per-topic mastery and streak history live on your dashboard, and the FAQ explains scoring and premium perks. Rankings update the moment a solve is verified in the browser — no submissions are counted twice, and guest solves stay on the device until you create a free account.
