volleyball

Hi ladies, so ive recently got enrolled in a new school. Ive meant a couple of friends and we r planning in playing volleyball this upcoming school yr. (going to be juniors). I know the a little of the basics in hitting. I really want to play but im scared not going to be good enough for competitive volleyball. I have never joined any sports or have been in athletics. Only pe class lol. Im planning on working out and practicing this summer. Also what is athletics is it like pe class but more intense or is it a class for the ppl that are sports. Do yall have any pointers or any comments...thank u a appreciate it
