How to find correct answers to questions that we were wrong in, int the challenge?

Question

I know challenges are meant for practice but it's not much use if I can't learn from and evaluate my mistakes??Is there a way already and if not how should I request the developers?

Answer 1

There is only one way remember the question or write it down and try to solve it after the challenge completes.
And about requesting the developers for answers, I personally feel that it will ruin the challenges. I know this is all for learning purpose but if you get the answers to all the questions without having to work for it then you are essentially not learning anything.
And also the number of questions are limited so if the answers are already known to you, it gives an undeserved advantage to the player. So I don't feel we should have that feature.
