It seems to me that the only real choices are Indiana Kelley and TCU Neeley.
For Miami, Spring admit is basically admitting he’s not up to par for Fall (they don’t have space for him in thr Fall but they think he could succeed so he’ll fill the space left by the few freshmen who transfer or drop out at the end of December). However, Fall is when freshmen bond and find their sealegs. And it doesn’t sound like they’ve planned anything for the gap semester to offset that.
SMU without his major is dicey. Is he even interested in EMIS? Would he have access to the Cox career services and fairs?
That leaves Indiana Kelley and TCU. They’re different enough that he should have a preference?
Btw, I agree wrt the (direct after BBA MBA" they’re only worthwhile after you have some professional experience. They function as a combination of networking and specific content that’s only useful after you’ve experienced what they’re about and that’s why a “direct” MBA doesn’t garner much if any “bonus”. The exception would be if you got a BA or BS in something entirely non business related and didnt have internships where you could show how your skills apply to the business world, but a certificate would likely be less expensive and as useful. Better yet, focus on those internships and transferable skills while in college.
