@Twoin18 is referring to those prestigious named scholarships like the Morehead-Cain at UNC, McDermott at UT-Dallas, Stamps at a bunch of schools, etc. that cover all/a lot of the costs and also come with various perks and opportunities. They tend to be fairly difficult to get, those, as they’re all pretty limited.
Even if you fail to land one of those, however, if you don’t get in to UMich and Kelley costs too much (you’re more likely than not to get a scholarship there), your best bet would be to go somewhere tuition-free or less and aim for a 1-year master’s (some management programs, some econ programs; Columbia has a ton across different schools and subjects, though you would want to avoid SPS; NYU has a ton too; also should avoid some) at a target school and try again. You’re likely to get scholarships from MSU that brings down costs.
