So I understand that Penn boasts a “One University Policy,” but would this allow me to take classes/conduct research with the medical school? I definitely get this applying to other undergrad schools, like Wharton/nursing/etc, but what about the professional programs?
Yes you can take classes at any of the schools, including the med school. You may need the instructors permission depending on the class however.
Also, yes plenty of research opportunities – you can work with any prof at Penn
Yes applies to graduate and professional programs too.
