Georgia Tech vs. BU vs. WashU

<p>I have to decide between these three colleges by the end of this month. I'm pursuing a major in biomedical engineering and these three schools have strong programs in this field. Georgia Tech is consistently ranked higher than the other schools with respect to its engineering department, but WashU is ranked higher just when looking at the overall schools. Georgia Tech is cheaper and a better engineering school, but I'd rather study in Boston. And Washington University is still on my list because its a very good school. I want an intellectual environment and an undergraduate research opportunity, but I still would like to explore the city and meet new people. Any advice?
Thanks.</p>

<p>PS: What would really help if someone could inform me of some differences between these schools or how one of them is really unique.</p>
