<p>Being from a small town in the south actually should help. School with unknown track record re admits is +/-.
Lots of school clubs, not such a big plus, Brown would rather see in depth activity in few (leadership helps).
Grade are most important, if one of those clubs=less time to study for straight A’s would reset priorities (and that holds true for all schools).
Your essays are going to be VERY important. Make sure they show you as a person, and why you belong at Brown (and “because it is a good premed school” should not be in there.)
You are going to have to stellar grades this year and next, a fantastic essay, great scores, and excellent references (about in that order).
It’s always worth a shot if you really want it.</p>
