Long time reader, first time poster

I need advice. I'm trying out for an all-star team on December 1st through December 3rd, (it's for half the season. the team is formed to cheer from December to April, and then if you like it, you tryout again for the whole season.)
The website for the team says they don't know what skill level it'll be, it depends on who comes to tryouts.
So what should I work on to be prepared?
This is my first time cheering since Kindergarten, and I'm now in 9th.
My jumps are fairly good, my motions are strong, and I cannot tumble.
Thank-You in advance!!
