I have just started playing tennis for fun this summer. I am 14 almost 15 in march. I have only learned tennis from my high school tennis coach. I am on the team. I'm in southern california I'm most likely going to sign up for a membership at this local tennis center. Probablly going to do 1-2 group lessons and 1 private lesson a week. I really really want to get to a high level even pro. I am determined. How can i get into like USTA tournaments? Is going into USTA the only way to get an NTRP rating?
