Question

please reply with a good description.

Answer 1

You got to challenge people of your level, or you are going to find questions of the level of you opponent.

Answer 2

Recently someone challenged me he is level 2 and I'm on level 3. The questions are too hard for me and he scored 3. How??

Answer 3

It's going to be between you and your opponent's level and to answer your question... let's say you're half way between a lesson at a certain level, the app is probably just going to assume that the lesson is finished for all level 3's, making it go above the difficulty you should be receiving.
