Northeastern is a very urban campus, they have had overcrowded dorms the last few years. Many students need to do their first semester abroad. With that said, we have good friends who go there and love it. There is always something to do.
Brandeis is a small suburban school with fantastic faculty and resources. The commuter train into Boston runs right through campus, so you can be in the city in 20 minutes. Waltham itself has a fabulous restaurant scene a 10 minute Uber ride away.
Wisconsin is has a stunning campus and a large active campus community. We have a friend who goes there and absolutely loves it! It is very challenging academically, but there are a lot of like minded, high achieving students, so it’s easy to find study groups.
All of these schools have their own pros and cons, it’s really about where you want to be, what type of school (large/small, suburban/urban), but you are lucky to have fabulous choices! Good luck with the decision making process!
