A.B. vs. B.S.E.: A Side-by-Side Comparison

Although the A.B. degree requires 31 courses and the B.S.E. requires 36, the difference is misleading. In the B.S.E. program, independent work and a thesis count as courses, while in the A.B. program, independent work is counted separately from the course requirements.

	A.B.	B.S.E.
Overview	Two years of general education and departmental prerequisites are followed by two years of independent work, departmental course, electives, and a senior thesis.	Basic science and math courses, departmental foundation courses, advanced departmental courses, humanities and social science electivesare complemented by independent work (usually in the form of a two-term thesis).
Departments	African American Studies Anthropology Architecture Art & Archeology Astrophysical Sciences Chemistry Classics Comparative Literature Computer Science East Asian Studies Ecology and Evolutionary Biology English French and Italian Geosciences German History Mathematics Molecular Biology Music Near Eastern Studies Neuroscience Philosophy Physics Politics Psychology Public Policy (Princeton School of Public and International Affairs) Religion Slavic Languages and Literature Sociology Spanish and Portuguese	Chemical and Biological Engineering Civil and Environmental Engineering Computer Science Electrical and Computer Engineering Mechanical and Aerospace Engineering Operations Research and Financial Engineering
