Will I get in?

As of now I have a 3.75 unweighted GPA (I’m in my second semester of my junior year of high school) and I received a 26 on the ACT. I am working to improve my ACT score by at least a couple of points. I have not done sports other than one season of cross country and I am apart of National Honor Society, Spanish Honor Society, and a couple other clubs.

What are my chances of getting in and what can I do to improve my chances?

Depends on the program to which you are thinking of applying. You are correct in trying to improve your ACT score.
