Ah, I thought you were talking about the student applying next year, not that they’d already applied and been accepted. Gotcha.
It’s hard to be absolutely sure that the difference will be worth it monetarily - if by that you mean whether the student will end up earning that much more with the Michigan degree. It will be a boost for job opportunities, certainly (summer internships and post-grad opportunities), but it’s hard to quantify how much of a boost.
