At Ohio State you can study CS through the College of Arts and Sciences or through the College of Engineering (one dept. offers cs classes). Either path requires a minimum gpa in a set of classes to apply to the major. Acceptance to the major unlocks priority registration for the upper division courses required for the major.

The university does not admit by major, your ACT and gpa are good so if you meet the Early Application deadline you can leave it in the match group as long as you don’t mind the cold. I will warn you though, Ohio State has become very popular in state and you may not have a decision until spring even if you meet the EA deadline.
