"

Grinnell's open curriculum encourages students to take initiative and to assume responsibility for choosing their own courses of study. The sole core, or general education, requirement is the completion of the First-Year Tutorial, a one-semester, four-credit special topics seminar that stresses methods of inquiry, critical analysis, and writing skills.[citation needed] All other classes are chosen, with the direct guidance of a faculty member in the student's major department, by the student.[1]
