that’s a really good price for Emory. there is no drop-off in academic quality at Oxford but it is certainly a different vibe and my kids would not consider it- too quiet. If your kid likes the small LAC vibe then it is a good choice. I don’t think the kids have trouble integrating into the Atlanta campus but keep in mind most upperclassmen move off campus Junior year so she will likely still be living with her Oxford friends, and will probably graduate with most of her closest friends being from her Oxford years. It’s small. Maybe like Haverford?
Personally, and this might be overstepping my bounds, living with her brother at GW feels weird to me, sorry. you already said she doesn’t want NC State because she wouldn’t want to live at home. sharing a pad with her brother feels almost more stifling for both of them, somehow. If you can swing a similar cost for GW but have her living in the dorms then it would be great.
Richmond sounds like a bad fit, although I am sure many non-Greek kids have great experiences there.
I think all of these choices have enough prestige to get her where she wants to go if she works. If none of them seem to really appeal to her then I might reconsider some of those big publics. Wisconsin and Maryland are big can be made small and she can find her place.
