What is xp ?

Question

Can’t carry on answering questions saying I don’t have enough xp.

Answer 1

XP = Experience points
You get them from completing courses, answer in questions, getting upvotes and playing challenges

Answer 2

XP: experience

Answer 3

Instead of using your xp to answer questions, go back and read the write up once more. Most of the answers are on that page somewhere. Occasionally, you get a question that is based on information further back. It still is better to find the answer yourself as you will learn it better so you can use it in the future. Getting hints doesn't help you learn this stuff, just leaves you confused and unable to program.
