In challenge I am getting 5-9 exp+ for a win and getting 20-28 exp reduction for each lose . WTF is wrong with Sololearn?

Answer 1

Khalid Shifullah The number of XP lost or won is based on the difference of XP in that language that both opponents have.
This is not necessary linked to the level of the opponents, as a high level opponent can start learning a new programming language and have low XP in it

This usually happens if you lose a challenge against an opponent that is at a lower level than you.
