What is my chance of getting into UW-Madison with a major in CS?

I forgot to point out my high school GPA.
I scored quite low in my high school studies. I must convert my GPA in American GPA standards, but I guess the overall GPA is going to be like 2.0-3.0 out of 4.0.

Do you think that I still have the chance to get into the univ. of Wisconsin-madison?
