All good schools. Do you want to be cold? Wisconsin. REALLY cold? Minnesota.
Do you have a particular area you want to study in chemE? If petroleum, go to Mines. If you want a little bit smaller school without the depth in humanities that you’ll get in the big university, go to Mines. If you want better sports, go to Wisconsin.
If they are all tied for you, pick the area where you want to live. Mountains, midwest, southern and closer to an ocean?
