i have about 3000xp in total and level 8 so how do some sololearn mmbers can earn 10000's of xp in a single day even if they win

Answer 1

The sooner you stop caring about the exp system the better.

It does not make you a better programer, it doesn't teach you anything.

It's just pointless grind and memorising bland uninformative quiz questions.

You're better of solving code coach problems and scouring the boards for interesting questions

Answer 2

You can earn xp if you solve the doubt of other people, but to get xp you comment should get up votes.

Upvotes increases our xp.

To get Upvotes give a correct, simple and stratifying answer.

Try to solve as many doubts as possible.

May this help you and have a good luck.
