I want to become a wolf biologist!!!!?

Well I just recently decided that I want to be a Wolf biologist. I wish I would have made up my mind sooner because I did take biology and biology to and passed both with an C average...Please understand im a typical teen from ever thing that has been going on I wasn't taking school seriously. I want to go back and show my full potential but I cant. I wanted to take zoology to better my chances with collage but I didn't know I had to take Chemistry to get into the class which I find being very irrelevant but cant change how they think. Please help give me some kind of advice its my senior year and its my last chance to clean up my act for good. So please help
