GW (both online and on-campus) likes well-rounded applicants. They also take a holistic approach to admissions, which makes it slightly easier to get into compared to other top 20 schools. Since your GPA is below a 3.0, it will be an uphill battle, but I'm hoping that your amazing experience will help negate that a little. Your test scores will help as well, although I'm not very familiar with the new MCAT scoring so can't give you an accurate comparison. Your LORs and SoP will carry quite a bit of weight as well. Fingers crossed!
