Most professional schools prefer, and many require, that students earn an undergraduate degree prior to attending professional school. This means that most students interested in the pre-health professions or in pre-law must declare a major in a subject area. Pre-Clinical Dietetics and Nutrition, Pre-Emergency Medicine, and Pre-Pharmacy are two-year programs, so it is not necessary for a student to earn a bachelor’s degree prior to going to professional school. For the other health professions, students may choose any major, but most students, nationwide, choose to major in biology. Other commonly chosen majors include chemistry, psychology, and sports medicine.
