NU IN?? plz help

What is the NUin program at Northeastern?
Many people around me apply to that program in Northeastern, and I can’t exactly find what that is.
Do you have a major for that program?

Not all destinations are open to all majors. These students must spend the fall semester of freshman year at one of these destinations.
