Is it possible to take individual classes at Kelley if a student is enrolled in CAS, say the History Department or English Department as an undergrad?
It depends which classes. Some of the classes in Kelley have prereqs of other business classes obviously, but I think you would be fine as long as you have the prereqs done. My Kelley compass teacher said that she recommended everyone take compass 2 even if you weren’t in Kelley. I’d check with your advisor to make sure though.
