You probably already committed. I would in your case go to MIT (or at least to Yale.)
My DC had half ride at UMD (Merit) vs. nothing in GaTech for BME and UMich.
Since UMD is far from top in the major, we felt that extra money (in our case around 100k for GaTech ) would pay back. However, DC rejected UMich because of money.
80K is possible for middle class in Maryland. Over 100k is way too much. Good luck!
