Just a few questions about cheerleading.....

I am probably going to try out for cheerleading at my high school in March. What do they usually expect at tryouts? Also, any tips on trying to get on the team?

I have wanted to do this for sooo long and heres my chance...but I need some confidence. I'm nervous! (and tryouts are 2 months away!!)

Thanks so much everyone!
Ack! Butterflies in the stomach!
