Question

Pi chart on the profile

Answer 1

XP can be gained by doing a multitude of things on Sololearn. One of the more popular ways (I would say) that people gain XP is via challenges, where you gain a certain amount of points everytime you win a challenge with the amount of points earned being dependant on the level of your opponent. Another way is by progressing through the courses Sololearn offers and earning achievements, giving you a certain amount of XP as you go along. Some other ways it can be done is by answering people in the Q&A section and getting a daily streak going, both of which not giving you too much XP but it can stack up if you do it enough.
The pie chart that appears on your profile shows what you do on Sololearn or what you have progressed at. The influencer section is affected by the number of followers you have, going up by 1% every 10 followers, meaning you would need 1000 followers to get 100%. The contributor section shows how active you are in the Q&A section, going up by 2% for every post that earns 5 or more likes. You would need to have 50 posts with 5 or more likes to get 100% for that section. The coder section is similar to contributor in the sense that instead of increasing based on your posts, it increases by 2% for every code that gets 5 or more likes, so you would need 50 codes with 5 or more likes to get 100%. The learner section is probably one of the easier sections to complete, and increased based on how much of the Sololearn courses you have gone through. To get 100%, you would need to go through every single one of the courses that Sololearn provides (not including the C course in the lessons) fully. Finally, the challenger section, as the name suggests, is influenced by the number of challenges you have won, going up 1% for every 10 challenges you win (in any language). To get 100%, you would need to win 1000 challenges.
Hope this helped!
