Note that Wisconsin and Minnesota have secondary admission to some majors after enrolling.
For CS, Wisconsin’s secondary admission is earning a C in a CS course – not hard. For Minnesota, a 3.2 GPA in pre-major courses is needed to assure admission; otherwise competitive.

However, for any engineering including computer engineering, Wisconsin may be more difficult to get into or stay in the major.
