Sololearn should maintain the standard of challenge

Question

I think you all will agree with me.
Here one question be asked again and again. That's why I am not taking challenges serious. It is easily to memorize all the answers .

And also sololearn should maintain the difficulty level.

Answer 1

SoloLearn -> Quiz Factory -> Rate Quizzes

Answer 2

There's not enough questions, agreed, but I guess that's a problem that'll disappear slowly with the Quiz Factory in place. I guess they should do better checks on approved quizzes than they do now though
