Students must declare a major by the time they have completed 60 semester hours of course work. To be admitted to the BS major, students must have sophomore standing and have received grades of B or better in General Biology I and II for majors with laboratory, or the equivalent. Students must take at least 48 hours and a maximum of 56 semester hours in psychology, biology and chemistry that will count toward graduation. A minimum of 15 upper-division semester hours must be taken from Downtown Campus faculty. No grade below C is acceptable toward the major requirements; i.e., psychology, biology or chemistry courses in which a student earns a C- or below will not count toward the major.
