challenge learning method [suggestion]

Question

If you think you like to learn more from each challenges you could check what is your opponent fault in each challenge. At first I check my fault in challenges and it was very helpful but now I check my opponent's faults and it help me to get more from each challenges.

Answer 1

Yup.... I always do this 🤙🤙

Answer 2

How does knowing your opponents' mistakes help you learn?

Answer 3

I never check my correct answers but it does not mean that I know the concept completely. Apart from Yes/No quizzes and calculation ones or typos, those quizzes that challenge your knowledge from a language could be checked in this way.
When I check the opponent's fault, in about half of them I think I could have this fault and I was very near to that.
It helps me to double check my programing knowledge.
