# Class of 2024 Requirements

## Overview

Computer science majors must take 8 departmental courses (departmentals) and do independent work. The minimum amount of independent work depends on whether you are an AB candidate (4 semesters minimum) or a BSE candidate (1-semester minimum). Departmental courses are any computer science course at the 300 or 400 level (except 397, 398, 497 and 498) and a specific set of courses in other departments (enumerated below). There is also a distribution requirement within the 8 departmental courses: you must take at least 2 Systems departmentals, at least 2 Theory departmentals, and at least 2 Applications departmentals. (Notice that leaves you 6 departmentals that are constrained, and 2 departmentals that are unconstrained.)

BSE candidates do independent work by signing up for COS 397 or 398 in the junior year, or COS 497 or 498 in the senior year. You are encouraged to do more than one semester of independent work; the second semester of independent work may be counted as a departmental. AB candidates do 2 one-semester junior independent work projects and a full-year senior thesis. Numbered courses are not used to designate AB independent work.

## Course Offerings

Current course offerings can be found here and historical course information can be found on the Computer Science Course Schedule.

## Departmental Courses

Any computer science (COS) course at the 300 or 400 level (except independent work) counts as a computer science departmental (graded). In addition, some graduate COS courses (500-level) count as undergraduate departmentals (COS 551, COS 534), depending on their content and structure. (Please ask if you need to use a graduate course as a departmental.) However, graduate courses rarely count as special "tracked" departmentals (see the list below for the few exceptions).

In addition, any 300- or 400- level Math or ECE or *Physics** or ORF course.** Philosophy 312,**** MOL 437/NEU 437, NEU 330, MUS 315, ECO 326, and SOC 414 count as departmentals.** On occasion, special courses with computational content from other departments may fall into this category. Note that it is very, very, very rare for courses outside the computer science department that are not cross-listed with the computer science department to count as track-specific (ie: Theory/Systems/Applications) departmentals. **Hence, in general, you will not be able to count more than 2 courses outside of the computer science department as COS departmentals. **

**Beginning with the Class of 2023 CHM 301, ECO 312, and Physics courses will no longer count as COS departmentals. *

** Course offerings can vary from year to year.*

Some regular courses are COS departmentals but do not count in any specific track, such as COS 351 "Information technology and public policy". COS 495, Special Topics, is a departmental but may be associated with different tracks (or no track) depending on content. Other one-time courses may also be departmentals and may count in one of the tracks depending on level and content. Check with your adviser or the undergraduate coordinator for up-to-date information.
