The B.S. degree is the most technical undergraduate degree in computer science. The A.B. degree has fewer requirements than the B.S. degree, and so it can be ideal for combining computer science with another rigorous course of study. The CSES major integrates technical training in computer science with study in digital ethics, law, and policy. The Concentration in Technology, Ethics, and Society provides a pathway for B.S. and A.B. students to obtain exposure to and literacy in the ethical, legal, and social implications of their field. Finally, the Minor lets students studying fields other than CS develop technical expertise in computer science. Like most universities, Georgetown designs its undergraduate programs in computer science to conform with the ACM-IEEE guidelines on undergraduate computer science education.<br><br>The B.S. program has nineteen required courses, and the A.B., thirteen. The difference in requirements between the B.S. and A.B. comes from reducing the number of required mathematics courses from five to three and reducing the number of required computer science courses from fourteen to ten.<br><br>Both the B.S. and A.B. programs share the core sequence of Computer Science I and II, Mathematical Methods for Computer Science, Data Structures, Advanced Programming, and Introduction to Algorithms, which prepares students to take any upper-level computer science elective. At this point the two programs diverge. B.S. students must take Computational Structures, Programming Languages, and Operating Systems, which provides these students with the required breadth of understanding of the field. Students intending to pursue postgraduate studies or seeking employment in most traditional areas of computer science are encouraged to pursue the B.S. option. B.S. and A.B. students are encouraged to complete a senior thesis. Finally, B.S. and A.B. students have the option of adding to their majors the Concentration in Technology, Ethics, and Society.
