I have to disagree with you on this. In fact what you say is true for BSMD applicants i.e. HS students since most get the opportunities to connections. As per traditional path, most students do shadowing, volunteering and research at their UG school or near by. Most T20 UG schools have medical schools and they have programs to provide shadowing and volunteering opportunities. So BSMD is more cooked for those with connections than traditional path.
Even though my wife was a physician she couldn’t get him clinical volunteering since her hospital was strict about age and she didn’t want to pressure anyone since BSMD is not top priority for him (or us).
