Well you should be practicing all your skills in basketball. Focus on the ones that need improvement and just "polish" the skills you already have. You should practice at least 3 times a week. They don't have to be long exhausting workouts either. 3-5 practices a week that last around 20-30 minutes long would be fine! If you can fit more it that's perfect! I like staying ahead in school and often just practice my dribbling and passing inside my house when my parents are out. Sadly I don't got a hoop but I'm making one in metal shop soooo it'll be interesting Anyway just do what you can! I think you'll have a great shot at making the team!
