Exp in sololearn
why does some people have 600 xp in a course and others only 300xp? how do you get more exp?
You can earn xps from challenges,courses and badges
I think challenges and if you use help or unlock in the course questions affect your xp
winning challenges in D respective course increases Ur xp in d particular course...
Bad answers might have deducted some xp. At least before the big change in xp scoring...
