Prerequisites

Preparing for the Major: Prerequisites

Students interested in becoming Environmental Studies majors are encouraged to complete the prerequisite courses by the end of their sophomore year, however students are not required to have all of them completed at the time of application. The prerequisites for the major are distinct for the two Programs (BA and BS).  Download a prerequisite and major requirements checklist using these links: BA, BS.
