Our son liked his four years at Georgetown (School of Foreign Service). The campus situation reminded me a bit of Brown to the extent that it is situated in a residential area, but next to a city (Providence in the case of Brown – a real city in the case of Georgetown ; )
Your SAT scores are below the mean for Georgetown, but probably still within a standard deviation? I don’t know what sort of offering they have in Data Science, if any. Definitely a lot of opportunities for summer internships in the DC area, if you are doing well academically in something Econ or Government related.
