That is great to have that perspective from their experiences.
Thanks for sharing a little more.
You have a great group of safeties in NC. Your guidance counselor will have a feel for UNC, but you should be good there with the update to the SAT score and being instate.
So feel free to pick a few more to shoot for and see where you land. Yes, your SAT score will make a difference with the understanding that you are not alone in this quest. Your Eagle Scout attainment should be highlighted. Find someone to help read your new essays you are pushing out.
Vanderbilt is a good one on your list. Georgetown could be of interest and has the similar prestige you are looking for. Brown is very different than Duke. Do a little research on the Ivies and similar tier and just pick one or two and spend more time on the next tier if interested in any of those.
Davidson or Furman could be interesting for you. Sewanee - The University of the South, maybe.
