Those who have been accepted with below average ACT scores usually have something “extra” sometimes known as a hook in order to be accepted. It’s not like they just accept students “just because.” These can be some things such as exceptional performance at a science fair or [insert other activity here], legacy, first generation, athlete, or some combination of the above. You shouldn’t be aiming for the “lowest possible point” although if you don’t apply, you will never know. A good suggestion is to apply and make sure you have reliable safeties and backups, as Case Western is getting more selective
I would agree to put more effort into finding schools where your ACT is about the 50%tile. If you are not a senior, then start studying for the ACT or perhaps SAT!
Use Case’s 50% percentile as a benchmark. Case does not have a minimum cutoff score. Make sure to apply to some colleges with ACT average around your’s and apply to Case as a reach school.
Like an above poster said, for ANY college, if you look at the lowest AP/SAT it is usually of someone who is exceptionally strong in some other area (has a “hook”), be it sports or music or the ability to donate to the college. So as MasterThinker said, you want to look more toward the 50% to see if you are in the ballpark.
