Do you know if you may qualify for some need aid or do you need to reach budget with merit?
Run NPCs at a selection of OH publics, OOS publics (which typically are not generous with need-aid to OOS students… so not worth applying unless there is the possibility of merit), and privates. That will help determine the type schools your son should target.
Suggestions for NPCs: CWRU, tOSU, Miami-OH (auto-merit, see the table on the website), UAkron, CMU, Lehigh, ULouisville, UI-C, Western MI, Wayne State
Cross posting with @DadOfJerseyGirl … agree there is no need to retake ACT/SAT with those scores.
