There are three definitions of university: first, it refers to a school that implements higher education, and it refers to a higher education institution that provides teaching and research conditions and authorizes the awarding of degrees, including comprehensive universities, colleges and higher vocational colleges. Two, especially in multi-disciplinary colleges and universities, there are generally various majors in philosophy and social sciences (liberal arts) and natural sciences (science and engineering).
Class placement is to divide a whole into several small parts according to a certain basis and divide all the students in the school into different classes.
