Highschool Co-ed Competition Requirements?

Hi, I made JV cheerleading for my high school. But, this winter I want to make Co-ed Varsity Competition team. Our school has won state 6 or 7 times in a row. Last year was the first time they didn't win state, but they still won 2nd place. I am a fast learner when it comes to stunting, but tumbling is where I'm not the best at. My toe touches are pretty good but pikes are terrible. What can I work on to make the varsity competition team? by the way, I know this is in the wrong section, but they dont have a cheerleading section..soo.. d:
