Maybe wait like 5 days before following up with them. I knew the day of the week they sit down to discuss applicants so I messaged them the day after they had their applicant review lol all about timing!
as for the other question, I will be starting the MM 1 year so I dont know about the other opportunities first hand but from what I gathered from reading on their website, forums, and talking to the admissions, they said usually they match with specialties more along the lines of internal med since that is what helps the greater amount of people and that usually aligns with the personalities of the students in the program if that makes sense. EVMS emphasizes community involvement, volunteer work and student run clinic so I think thats why they dont really have a large number of people matching Gen surg, anesthesiology etc. And unfortunately, I did read (I dont remember the source) there isn't many opportunities to get involved in research. I get the concern about the match/residency situation but keep in mind, people have gone to the Caribbean's and matched into Surgery and Radiology. I too am looking into something a bit more competitive but that will all depend on our Step scores.
