How should I get ready for a Handball Tournament?

My school has a handball tournament every year. This year I am participating but I am really nervous! It is a singles competition but I want to know how I can prepare for this tournament. How can I become less nervous and win!|||To get ready just practice and play handball at school or at the park with your friends. There is no need to be nervous because if you practice you will do very good! So just keep practicing and good luck!
