Overview of Departmental Majors
"All Princeton undergraduates have to select a major — formerly known as a concentration. This is the departmental program of study that leads to your degree, either a Bachelor of Arts (A.B.) or a Bachelor of Science in Engineering (B.S.E.). If you are in the School of Engineering and Applied Science, you will choose your major at the end of first-year. If you are in the A.B. program, you will choose in the spring of your sophomore year".
