leaderboard scores; What's the difference between all three scores? How do you earn points for each score?

Question

#1 The main score ?
#2 the (your) current XP score?
#3 the XP score (To get you to the next level )?

Answer 1

you have a total points by language and a total sum of all language.

-> around 200 to 500 total by each language
-> 1 to 30 point each challenge by weapon

-> show code you are working and get likes
-> most likes on answers or questions

on skills there are several areas
learner -> languages courses
coder -> more liked code you published
contributor ->acepted quiz and submissions
influencer -> likes on answers and questions
challenger -> won challenges

hope it helps you
