These are basically peer schools. What are the requirements to keep your scholarship. BU is notorious for making it really difficult (3.5 GPA?). Northeastern only requires a 3.0 which allows you to take more risks and explore. If you’re not going to explore in college, when are you going to?
In terms of campuses, they are equal, they are walking distance from each other. They both have a Green-line trolly running through them. Northeastern has more green space and the Fens. BU has the esplanade.
Frankly, I’d favor Northeastern because of co-op and I suspect its easier to keep scholarship.
