Based on your Avatar my Vote is Ohio State.
My D graduated last spring with degree in CHEM-E with honors and a minor in English, and is now gainfully employed with an awesome company in Ohio.
Nothing but positives her whole 4 years.
She too had the same picks MN,Purdue and OSU as well as Michigan and UIUC. After visiting all and looking at the financials, never any doubt, OSU wins hands down!.
For an undergrad CHEM-E degree all these schools are great and virtually identically as far as any potential employer is concerned. For a high stats low need student, I am sure OSU provides a much better freshman merit scholarship.
My Son just committed to OSU for CSE. He also visited, applied and was accepted at MN and Purdue.We are OOS (IL).
OSU financially is a better option for us with freshman merit than his in-state alternative UIUC.
