Will I be admitted?

'm a senior and I have a 3.2 unweighted GPA with a 23 ACT. I will be taking the September and October ACTs so there is a possibility I could increase my score if needed. I also did Key Club Junior and Senior year and I also have around 30-40 hours of volunteering. My Top college choices are Northern Illinois University, University of Illinois at Chicago and DePaul University. (in state if that makes a difference)
I really want to get into one of these Universities so what do you guys think my chances are? How much should I improve my ACT score to guarantee admission?

Also I forgot to mention
-I only have 2 AP classes (AP Human Geography and AP psychology)
-5 on AP psych exam
-1 dual credit class (anatomy and physiology)
-4 years of math, 4 yeas English, 5 years social studies and 5 years of science.
-2 years foreign language

My highschool does not rank btw.
