MSOE is a great school.
Pricey but worth every dime if you are motivated to apply and get accepted!!
And it sounds like he is packing his bags and moving to Milwaukee.
It is not a huge party school, think Sheldon from the Big Bang Theory.
He could start with his eye on IE but as he becomes enriched in the culture at MSOE; he may turn his eye towards Biomedical Engineering or Fuel Cell Technology. Milwaukee is a hot bed for grabbing talent out of MSOE for the General Electric Medical Headquarters in Waukesha, Wisconsin or Johnson Controls in Glendale, Wisconsin
MSOE is a breeding ground for students that have an eye on "making their mark in the world," thus leaving the making the "world a better place to live," college majors in the dust at other Wisconsin Colleges and Universities.
I wouldn't worry.
Almost every kid enters college with one major and graduates with a different major.
Most of all -- Congrads!!!
