Competitive Gymnastics?

Okay, so I was a competitive gymnast from the age from 5 -11 and then I quit, when I was 13 I started taking a once a week, hour and 10 minute long advanced cl, but I want to get back onto competitive, I did train with the comp girls this summer, but I want to do it all the time. I can still do the basics, like cartweel and handstand on the highbeam, backwalkover and front walkover, kip, pullover and roundoff double backhand-spring. What can I do to impress the coach and try and get back in and what can I do at home to practice. I just tured 15. Wow this is long. Thanks xoxo
