How do I genuinely get better no B.S. Tryouts are in 2 weeks and I’m trying to get better because there are 44 ppl trying out, What can I do to stand out. What are something’s that I should work on as a shooting guard, stuff I have trouble are moving around constantly, stamina, and making the right play because last season at my middle-school I kept on making stupid turnovers what should I do to improve

I’m a freshman in highschool and my teams tryouts are in 2 weeks there are gonna be 44 freshman trying out and I already know that a bunch of people are going to be good what can I do to stand out, or like drills. I also need to work on conditioning any tips on that because my stamina is so bad.
