Just looked at the three states. For residents for cheapest to most expensive it is Wisconsin, Iowa, Minnesota. It is cheaper for MN folks to attend Wisconsin schools than any other out there. I will say talking to my nephew who goes to the U and is wanting to get into their "business" school it seems pretty nasty tough. He has a 3.55 and needs to about 4 point the next semester to get where he needs to be for admittance.
that's interesting. I knew they had an in-state tuition freeze for a while now but IDK how much longer that's sustainable. Think they put a limit on how much the out of state could be raised but not sure I'm recalling correctly on that.
