How can i make the cheerleading squad??

I dance, and i have a lot of leg strength. I need to do something to tone my arms but not too much. And i know how to do a front word summer salt, but i need to know how to do a round off, cartwheel, and handstand in 2 - 3 weeks. Im starting a cl but its running round offs but they could help me with my practicing though? So basicly i need to know how to do a hand stand, backwards summersalt, cartwheel, and roundoff. Then i need to know how i can excercise my arms and how i will see the fastest results for everything????o yeah im in 6th going in 7th for the cheerleading!!!
