Why is BC listed as the college in Boston? Of the four major schools BC, BU, NU, and Harvard BC is the smallest in terms of number of undergraduates. BC is around 7,800, Harvard 1200 NU 15000 and BU 30000. Their science and engineering departments suck/nonexistent compared to the ones at the other three schools. They shouldn't even be called Boston College since their campus and housing is in Chestnut Hill. At least Harvard has/ is expanding into more of Boston.
