Question

I can go to testing cases but not getting any xp.What to do?(I'm not a premium user)

Answer 1

go to your profile and click on solutions tab then choose a code coach and choose a Programming language then submit your code there.
there many free ones.

Answer 2

There is a run button, hit on that. or tap on output to see result of your program..
Edit:
What actually you mean?
If any test case is not passed, then it is still unsolved. After solving problem only, you will get xp..
