Hi ...would anyone please tell what is the "score system" or "xp system" used in sololearn challenge?

Question

how sololearn calculates the score of challenge..?
example :
3xp ,9xp..before challenge+5 challenge questions.
and is the level of the opponents make difference?

Answer 1

You can find the details here:

www.sololearn.com/FAQ

That said, XP gain/loss is more dependant on language XP instead of level.

Answer 2

@Hasty Rei ..

the sololearn FAQ say that "Calculations take the oponent's level into account" and "used a modified version of ELO rating system"
