Ewelina xp's are known as experience points which is use to determine your level on the platform. After a certain amount, you unlock new levels until you get to the ultimate platinum level.
You can acquire this points by;
- Challenging(Which is the easiest way to get more xp and level up faster).
- Answering questions in q&a.(Only answers marked as best gets xp. 10 to be precise).
- Unlocking Badges. The badges have been categorized based on the challenge and answer system. Check profile for more details.
- Winning COTD(Code Of The Day. This feature doesn't function anymore).
These are the only ways of gaining xp.
Jakub Stasiak allow me to correct you. When answering questions, pls avoid every possibility to misleading/misguiding. If you say answering questions, try to be more specific. Answering questions don't earn you xp rather getting answer marked as best does which is 10xp as I stated above. Also the badges you get must have gotten you to gold level :)
Thanks for understanding!
