First off, depending on which big ten school he is at, it may be smarter to just stay there and switch majors. A lot of big ten schools have great business programs for publics.

That being said, if he is at a school with a not so good business program, would it be possible to transfer for the spring semester into a better school than the small private option that is currently available? Just a thought as I don’t think a small private university would provide many opportunities for business.
