You can answer these questions by looking through my post history. Pulm/CC.
Let me help you wade through the BS
@Goro is writing. He's trying to confuse you on purpose. First you have to realize that
@Goro is just a member of a committee comprised of multiple people and an admissions dean who can overrule him and has to take into account the best interest of the school by making sure he fills all the seats and keeps the fail/drop out rate low. So while
@Goro may be recommending they reject those with IAs like the ones you mentioned it sounds like he routinely gets overruled. In general DO schools are not particularly competitive but at the same time want to keep their admission stats high. A great way to do this is to accept students with high stats and blemishes on their record since US MD schools have the luxury to pass on the majority (but not all) of these students. While they pay lip service to a "holistic approach" to application review all that is trying to do is encourage lower stats individuals to apply because without them they can't fill the class but they know that seemingly higher admissions standards are a great marketing tool so they'll try to pad the stats by taking a risk on people like OP.
Assuming OP has high stats (which he probably does if he got into his "dream" school) I bet after putting a couple years between him and this incident he may find at least one DO school willing to give him a shot.
On the other hand when
@LizzyM says that they categorically reject anyone with anything more than just a minor IA at her school I believe her because she's at a top MD school.
