In terms of major flexibility within UMich LSA, there’s no significant barrier (department approval) to switching majors, adding majors or minors. Roughly 75-85% of LSA (and CoE) students switch majors at least once, according the info shown us at orientation a couple years ago. You can vent propose you’re own major.
The only major barrier is if the LSA student wants to transfer in to the Ross Business School. Ross allows about 100-150 inter-school transfers per year. Even transferring into CoE from LSA is reasonably obtainable.
Also, UMich has a major called Biology, Health and Society, which is a bit more “expansive” with courses from Sociology and Education departments. IIRC.
