I never did this, but when I was at Louisville there was a Metroversity program. You could pay your tuition but could take up to X credit hours per semester at another Metroversity school without paying extra (think they were U of L, Bellarmine, IUS, Spalding and JCC back then, now it includes the two local theological seminaries as well.)
It was a good deal if you were at JCC and wanted classes anywhere else, or if you were at Louisville and wanted something at Bellarmine.
