It's my understanding that Arkansas law requires that a relatively equal number of students from each district be accepted. There may be some caveats to this, but I'm not really aware of any, except that the admissions committee has a little bit of leeway with regard to OOS students (meaning a certain percentage of the class can be OOS), and that there are a few slots that can go to a qualified student from any district after a certain portion of the class has been filled.
All of that to say, I know plenty of people from the district 4 area in the class. We don't typically share stats with one another once we've been accepted, though, so I can't help much there (you'd be surprised how little your undergrad experience matters once you get here). Sorry I couldn't help more!
