Could I make Varsity?

I am in 8th grade and I have been cheering for 4 years. I want to try out for highschool Varsity. The football squad only had 2 girls that weren't seniors, and the basketball team only had one girl that wasn't a senior. Since for the next year, all the seniors are going to be graduating... Could I make varsity? There was only 4 girls on the JV for football and they will probably stay there. There was about 7 for the basketball varsity. I know a few will make varsity. I am a flyer and 5'4" and 85 pounds. I can twist down and full lib. I have a heel stretch on both sides and I have my scorpion. I can do a roundoff with 2 backhandsprings. My jumps are pretty good, but need a little improvement which I could fix by tryouts. (I have no idea when tryouts are.) I have been dancing since I was 3 so the dancing part isn't a problem. I have plenty of experience. Do you think I could make Varsity? I really want it. I KNOW I can make it for Football Varsity, since not a lot of girls are trying out for football. I really want to make Varsity for basketball too. I am willing to do anything. There are a lot more girls trying out for basketball too. Do you think I could make it?
