The tunnels are nice but most of the newer lecture halls don’t have these, I would say these only worked for 2/9 of my classes as a health science student.
As a former NU student, I can tell you it's NOT that great of a story. We have a new thing called GLOBAL WARMING AND THE INTERNET. Boston has recorded its hottest winters on record for the last 6 years and online education has grown double-fold. It may be time to retire.
