Besides academics, there are many other ways that college supports success. Cross-cultural experiences teach you to relate to and work with different cultures, as well as providing you with global context. Personal relationships with professors create opportunities for research, as well as networking and reference letters. Tutoring and writing skill development counseling can also provide academic support. Attending a private college can further promote success. Private institutions offer a 53 percent four-year graduation rate, as opposed to a 33 percent for public schools.
