What will i need to know if i want to be a freshman JV. cheerleader?

i can do the splits right, left, and middle almost i'm like 2 in away. i can do a kart wheel and a round off. i'm not sire if i can yell i haven't really practiced. i know all the arm movements idk if there are more. i know touchdown, high V, T, broken T, low V, and low touchdown. i'm pretty muscular but i don't have very good endurance, i get like a 12 minute mile :[] . my arms are kind of weak i do girl push-ups. my high schools cheer squad isn't competitive i think it goes to a few but it isn't that hard core.
