There’s a big difference between $250K and $400K. Some may give a little aid (like a Princeton) at $250K. $400K - no way. And then there are assets - if they have any level of assets, you are getting nothing.
So at $60K, you need to find schools that give merit.
The Econ Olympiad is great as is the rigor but the Bs stand out. You’d like to avoid schools like Tufts, BC, Emory, WashU - so does that mean you want to go above?
You won’t be able to afford those mid tier schools or above.
And I’m not sure you’d get in.
But you need to find schools that give merit.
So I’m thinking these where you need no merit:
Florida - match
Georgia - match
Georgia Tech (reach)
South Carolina (Honors) - you’d have merit for sure
Charleston - here, you’d want to get Fellows (reach) - where you’d be part of a small group in Honors - that gets lots of enrichment. Without, it’d be at the top of budget and too pricey when off campus although you’d likely get small merit - but you wouldn’t likely want to attend if you didn’t get Charleston Fellows.
Where you might consider that requires merit to get to your cost:
Brandeis - I think you could get to $60K with merit but not assured. Likely.
Case Western - I think you could get to $60K with merit but not assured. Match - you’d need to express interest
Davidson - reach, because you’d need the Belk scholarship - but high target admission
Franklin & Marshall - likely - need enough merit
Furman - safety - likely to get enough merit
George Washington - Safe - but you need enough merit
Grinnell - target - I think you’d get in because of who you are and where you are from - and merit is possible but you’d need.
Kenyon - safety - need enough merit
Lafayette - likely - need enough merit
Macalester - likely, need enough merit
Minnesota - safety - will achieve with merit
Pitt - safety - need merit
Richmond - target but need merit. Could happen.
Syracuse - I think you could get to $60K with merit but not assured. Safety.
W&L - reach, because you’d need the Johnson scholarship - but low reach admission
W&M - target - but need merit - possible but not likely
Vandy - reach - but you said you don’t want a Wash U type - they have tuition scholarships but they’re unlikely to happen.
Of course, you have your in state schools like UMD, UMBC, Salisbury. And you might put UMD above many that I’ve listed - and it’s a fine school for a large public.
Given your budget, these are the types of schools you might look into. I don’t see the creme de la creme as necessarily admissible but even if they were, you’d be $40K short a year unless your parents raised the budget.
I should add - there are many LACs and other state schools taht would achieve your budget - and you could get down to low $20Ks at named flagships.
And I would somehow weave your Etirea / URM story into your app somehow.
Good luck.
