If your parents are fine with paying(half tuition seems reasonable at your income) and you are set on Biomedical Engineering then I would probably take Johns Hopkins. I don’t trust US News too much but they have Johns Hopkins followed by Georgia Tech as 1 and 2 for biomedical. That’s graduate but I’d assume you’d find really strong undegrad programs at both. If the money isn’t a problem though you’ll probably have a better undegrad experience at Hopkins with smaller classes and a better location. Also it seems like there could be some interaction with one of the top med schools in the county but I could be wrong. Either option would be great and all your other options are very strong but I’m not sure all would offer you biomedical engineering.(fairly confident it’s not offered at Olin and my impression is that most ivys aren’t known for engineering)
