How Do I Become A Cheerleader?

Hey. I just needed some help and wondered if anybody here could help me. I want to become a cheerleader, more than anything. I am not very flexible and I`m trying to work on that. Tryouts aren`t until High School, but I am in the 8th grade and I need to shape up or I won`t make the tryouts. If anybody has any tips or anything to offer me at all, please don`t hesitate to contact me.How do I become a cheerleader? If anybody has any advice, that would be great. Thanks!
