In both the US and UK "college" can refer to some division within a university that comprises related academic departments such as the "college of business and economics" though in the UK "faculty" is more often used. Institutions in the US that offer two to four years of post-high school education often have the word "college" as part of their name, while those offering more advanced degrees are called a "university". (There are exceptions: Boston College, Dartmouth College and the College of William & Mary are examples of colleges that offer advanced degrees, while Vincennes University is an unusual example of a "university" that offers only associate degrees in the vast majority of its academic programs.) American students who pursue a "bachelor's degree" (four years of higher education) or an "associate degree" (two years of higher education) are "college students" regardless of whether they attend a college or a university and refer to their educational institutions informally as "colleges." A student who pursues a master's degree or a doctorate degree in the arts and sciences is in AmE a "graduate student"; in BrE a "postgraduate student" although "graduate student" is also sometimes used. Students of advanced professional programs are known by their field ("business student", "law student", "medical student"). Some universities also have a residential college system, the details of which may vary but generally involve common living and dining spaces as well as college-organised activities. Nonetheless, when it comes to the level of education, AmE generally uses the word "college" (e.g., going to college) whereas BrE generally uses the word "university" (e.g., going to university) regardless of the institution's official designation/status in both countries.
