Planning to do Science Olympiads in my Senior Year

I know my course rigor, scores, and GPA are not the greatest, but is there a chance of me getting in? I’ll probably be writing my essay on how I progressed through high school, as I started off really bad, being in all regular classes. I came to my senses in 10th grade, explaining my weak course rigor. Do I have a chance of getting in? What more can I do senior year to better my chances? I also am visiting the school this Saturday if that matters at all. Thanks very much.
