Dartmouth College is famous for its high quality undergraduate education in LVY League. The essence of Dartmouth undergraduate education can be concluded in three aspects. First，it insists on the education theory that combines liberal arts and professional education while encouraging students to develop a broad horizon in different areas. Second，as for the education mode，students are encouraged to study based on their own interests and personalities，while the college will offer great opportunities of overseas study so as to not only develop world vision but also unify learning and practice.
