Mckenna shows you a typical classroom and lecture hall
These are two classrooms in Fulton Hall. The smaller classroom is still larger than some other classrooms in other buildings on campus, but these will typically hold more specialized and higher level classes that you'll take as an upperclassman. The lecture hall will hold a maximum 250 people and that is the largest that a class will get at BC, however, they are almost never that full. Those will hold introductory level classes and you will likely only have a few classes that are this style at BC.
