@shiftitamanna, That is very common for students who have a good memory to learn classes by heart, although without analyzing the content, which of course does not bring good results at exam time.

I guess that's what happened with you and you couldn't perform well during the exam.

Certainly to achieve success you have to make mistakes since nothing comes easy and success is one of them.

You are a young person who, as time goes by, acquires knowledge and experiences that, from what you say, you also share with your circle of friends.

In other words, the accumulated errors between you and your friends are a great source of information for the personal growth of each one of you.

"You learn from mistakes and knowledge is power."

I say goodbye wishing you have a happy night.
