I got tryouts tommorow.... any tips?

Hello everyone. First of all, I am 5'9", 140 pounds and 13 years old. I've played basketball for 2 years in a recreational league and never really tried or cared, this year I found the pion for the sport of basketball and began to practice everyday. Since June 20th I have played basketball at lifetime fitness 3-6 hours everyday and practiced shooting, dribbling and games. I usually start with some dribbling drills, then an hour of shooting, then play 3 on 3, 5 on 5 or 21 with other people. I work my *** off everyday and suprisignly I don't get tired anymore because I'm used to it now. The reason I have been practicing so much is because I want to make a traveling team (it's close to AAU but just a bit lower level). There are 3 teams A team (best), B team (second best), and the C Team (worst of the three.) I honestly want to make B team because I feel that is my level although maybe I could make A and maybe C. I play with adults mostly and rarely kids my age and they tell me I'm a lights out shooter and that I've got good postmoves. Some of them say I have an amazing mid-range j. I am a big guy who can handle the ball pretty well (although that's an area I need to work on) and I am a great shooter who loves driving in the lane and using floaters, layups or bank shots. My vertical is 22 inches and I am a great blocker because I love to time the opponents shot. How can I make the team? How do I prove myself? I know there will be a few drills we need to do in order for the coaches and scouts to see how good we are. Theres the Mikan drill, dribbling full court with your right and back with your left, and dribbling between the legs then behind the back and so again. What are your thoughts on my determination? I truly am a good player now.
