All personal knowledge and opinion!
Yes, Mercer typically matriculates waitlisted students because applicants (w/ MCG acceptance) go to MCG (because $). That being said, year-to-year cycles are irregular, so this year may be different. In addition, they selecte waitlisted applicants March 31st, and interview are almost filled.
Thank you dacebaMD. I am just wondering because I interviewed last semester, but have yet to hear anything still. My friend who interviewed in October just got the call last month so I'm still praying I will get one sometime this cycle.
