UNC-CH accepts no more than 18% OOS students as required by state legislature. That can mean that in any given year it can be less than 18%. All priorities are given to admitting and educating NC residents. So many times it is a big reach for OOS atudents.
Younger son attended undergrad in NJ as an OOS (private undergrad) and attended UNC-CH for med and business school as an in-state resident (NC). He very much enjoyed Carolina!
And again preference for med school admittance at UNC is given to NC residents.
The previous advice to look to your in-state options especially when looking to future plans for med school is accurate.
