I dont know too much about Auburn. However, ACOM had an average gpa of 3.4 and 26 MCAT this year.
Its not necessarily that all of the DO schools are shoo-ins. And especially with the MD/DO residency merger that just happened a few weeks back, I bet you anything this year is going to spike in competitiveness. Either way, most have been slowly working their way up in average stats year by year. Some of the newer ones (that even DOs question their existence) have much lower stats. Think like 3.3 gpa and 24 MCAT... Others that have been around for 90+ years are very, very competitive - pretty much on par with a lot of MD schools (think like 3.6+ gpa and 29+ MCAT). Even some of the ones that were made in the 70s are pretty competitive.
What are your stats like? Any ECs? Have you shadowed a DO? I dont know about ACOM, but a lot of DO schools "strongly recommend" (ie require) a LoR from a DO. So that is something to also think about, with the season coming up.
