When do users get an answers bonus after completing a challenge?

Question

i answered everything correctly and won. but no bonus.

Answer 1

Because, they answered correctly new questions. I think you get 3XP for each new question answered right.

Answer 2

Answer bonus will be given for a question if it's the first time you see it, I think...

Answer 3

@Gami
it means that it is not a new thing even if the question being very hard is attempted correctly for the first time

Answer 4

I only got then when either myself or the course was new, I was actually quite surprised when I started winning challenges. Now I'm too sensitive about protecting those points😑
