Wisconsin is a gold mine at the grad level everywhere you turn. But undergrad is a different story. Large classes, TAs and less personal attention are the rule and likely to worsen significantly with state budget cuts coming.
Northwestern still recruits a class an academic level higher and has little of Wisconsin's funding woes.
But $12k/ year is not nothing. Unless your 4 year undergrad degree becomes a 5 year at Wisconsin due to class lockouts, it will be hard to justify spending this kind of money and then taking on med school debt on top of that.
