High… Your ACT is really good. I have friends who applied to Mich that didn’t get in because their ACTs were too low. Many people don’t know this, but Mich is actually a pretty competitive school to get into. Your ACT and EC’s will set you apart significantly. From what I see, you’ll get in to Mich easily and Penn is actually a mid-low match. Now looking at it, U Chicago is a mid-low match. I live near it and thought about applying but decided not to because I didn’t do well on the ACT. Your ACT is more than enough to get in. Hope this helps!
