Each student in the major must complete 12 hours in an emphasis area that is an extension of the major. Examples of such tracks include public policy, geoscience, and molecular ecology. At least eight of these credits must come from 3000 or 4000 level courses. The courses in the emphasis will be selected by the student and his/her advisor and must be approved by the department chair. This set of courses will be sent to the registrar and will become part of the student's academic file.
