You do not have to be good at sports or be on a sports team to get into a sports school. However being good at sports might increase your chances of getting in. But if you are smart and you really want to get in I would try to get in
Any sports are good sports ... for anyone. You don't have to be a tomboy to be good at sports! Try learning a little about different types of sports and see which ones are most interesting to you! You can google anything and learn more about it.
