How do i make the high school basketball team?

5'7", asian, cannot touch rim, going to be a junior, have decent jumpshot and defense... i think. i have been going around looking at what answers people received to similar questions but i guess i wanted something more. i think i lack some of the fundamentals of the game. Any free tools i could use to get better? dvds? websites? and also, when giving advice, im trying to grow so im trying to stay away from building calve muscles or squatting because they stunt your growth. so take that in mind. or correct me if im wrong. so what specifically should i do? what drills? how can i learn to read the floor better? how can i learn the fundamentals? i guess im just trying to get every aspect of the picture. so could you guys suggest some useful advice to this disappointed man? oh, for reference, i got cut 8th grade and 9th grade. i just didnt try out in 10th. so please, thanks for taking the time to read this and i wish all of you the best in whatever you are striving to reach.
