First I would not put GW in the same class as Harvard.
For a non - disadvantaged applicant to a top tier medical school such as Harvard: GPA of 3.8 or higher, often a 4.0; MCAT over 90percentile, often in 98+ range; 3 or 4 letters giving the applicant the highest recommendation eg in top 5 percent of all students or even the top 1 percent; evidence of leadership e.g., President of an undergraduate student association; excellence in either a 1) research setting as evidenced by sustained participation in a lab and coauthorship or even first author on at least one paper in a peer reviewed highly rated journal or evidence of independent research scholarship; or 2) evidence of sustained participation in a community or public service related to medicine preferably showing independent initiative eg starting a community clinic or a service for disabled children. In addition many students excel in a hobby or sport. Most but not all score over 50% on the MMI if the school uses this.

Your family can donate a huge amount of money to the school. That works too.
