Brilliant&apos;s **Leagues** are weekly competitions where you compete against other learners for the most XP in a given week.

You can earn XP by completing lessons and practice. Each League is comprised of 30 learners.

Leagues begin and end every Sunday at 8 PM PT/11 PM ET. When you earn XP for the first time in a given week, you&apos;ll automatically join a League.
