Dartmouth College requires that all majors must complete a substantial, graded culminating or integrating activity in their major. Many chemistry majors will satisfy this requirement by participating in undergraduate research by registering for one or more terms of CHEM 87, Undergraduate Investigation in Chemistry. The Chemistry Department offers five major programs. All major programs require an average GPA of 2.0 in all courses counted toward the major, including prerequisites taken in Chemistry. Normally, all courses that would serve as prerequisites to, or count toward a major in Chemistry, and that are presented at the time the student declares a major must individually have a GPA of 2.0 or higher. Three of the major programs are offered as majors in chemistry: Plan A, for those who wish a broad and thorough training in chemistry; Plan B, for those whose scientific interests are only partially based in chemistry; and a modified major, which is similar to Plan B, but also includes a second program involving another college department.
