I was the funniest person in the class so they used to like me .

No doubt about it, even reading your post I can sense that you are a very funny person and I like people who makes fun.
Sorry about your child hood experience, my condolences.

I was given an opportunity and when we started the exams everything went successfully on my side and I was the first in our class

Your experience here proves that we can achieve any positive thing we set out to do.
You forgot to invite me for the contest. Enjoy your day. Best wishes.
