What you have ever tried to overcome nervous?

I've got this weird habit to overcome stage fright and nervousness. I put a coin in my shoes and after that I feel like I'm confident to speak.

Hmmm.. first that you might want to do is to study hard so you know as much as possible about the questions that might be thrown at you. another thing is make sure that you are had enough rest and try to pamper yourself as much as possible the night or the day before your exam. in my case, i ate the food that i wanted, tried to get long hours of sleep, and on the day of the exam, i tried to look for the best outfit that i can wear. i need to look and feel good. and most of all, never forget to pray. it really helps...
