My d graduated from and loved Georgetown (one of her friends there majored in environmental science and loved the experience and landed an amazing job in the field right out of college). Other schools she liked were Boston College, Vandy, Northwestern. all of these highly selective of course. George Washington is a very common back up to Georgetown among her friends. It wasn’t for us (way too cold and way too religious) but Notre Dame is another school a lot of Georgetown applicants apply to. For those who love DC, American and George Mason are popular GT backup schools.
