College cheer with no high experience?

I had a knee injury freshman year that has basically prevented me from doing any physical activities for my high school career. I will be a senior this year, and I think my knee is FINALLY strong enough for me to be able to move! Due to these trying years, I have gotten out of shape which is very hard for me, seeing as it is important to me to be healthy and in shape. I have no prior experience (besides elementary dance and gymnastics), but want to cheer for Penn State or CSU (preferably PSU). I will be meeting with a coach Tuesday for private 1.5 hour lessons to begin conditioning, tumbling, and dance. What I want to know, is if it's even worth it. Since I am basically starting from scratch, can I still make a college team? I definitely have the looks and the personality, it's all about technique now. I want honesty, it wont do me good to beat around the bush. All I can say is that when I want something, it becomes my obsession. I am ready to work HARD, and perfect what my coach teaches me. Help? Please and thank you :)
