Your #s give you little chance. That said, you are a URM and first gen and then can help. Brown lags vs. others in diversity based on what I read.
If they’re looking to increase diversity, you can have a shot. I hate to say it like that- but that is your chance.
On the merits of GPA/SAT, you have near zero chance.
That said, your stats and extras are sensational and there’s many a great college that will benefit from your presence and I’m sure you’ll do great.
Good luck.
