BSMD/BSDO Applicants Undergrad and Medical School experiences

Again what’s the need to do clinical volunteering in home city? My kid didn’t do any at home in 3.5 years since he had every thing available at Vanderbilt and spread it out during academic calendar . First two summers he was hardly at home, he went abroad for research and public health project funded by scholarships… he did some shadowing locally since wanted do check more specialties.
