Bachelor of Science
The Department of Computer Science offers students in the College of Engineering a Bachelor of Science degree.
This program introduces students to core concepts and cutting-edge topics in computer science. The program provides students with hands-on experience and a depth of understanding of computer theory, systems, and applications that prepares them for successful careers in computer science and to participate in the next-generation of technological advances.
Requirements
Courses required for the major MUST be taken for letter grades. Pre-requisites are strictly enforced for all CS courses.
General Education
You can obtain a detailed list of GEs from the College of Engineering Undergraduate Office via email at coe-info@engineering.ucsb.edu. Please refer all GE-related questions to the College advisors.
For information about requirements for College of Engineering majors, including Computer Science, and other program information, see the GEAR (General Engineering Academic Requirements) catalog associated with a student's year of entrance to UCSB.
All students must achieve a grade of C or above in CMPSC 16, 24, 32, and 40 to take any course for which any of these courses are a prerequisite.

ENGR 101 | 3 | Ethics in Engineering |
NOTE1: Effective Winter 2022, students must attend a department faculty advising event in order to complete the "prior approval of major electives by faculty" requirement. We no longer require students to submit any forms since attending an event is required.
NOTE2: Effective Fall 2024, the "major elective approval" is no longer required in the CS major. Students may opt-in to change their CS major catalog year to follow the newest 2024-25 major requirements.
As a graduation requirement, all Computer Science majors must receive faculty advising by attending a department faculty advising event. The best time for students to receive faculty advising regarding a range of topics such as research, internships, and elective courses is in their Sophomore year (typically your second year). Students that participate in and attend a department faculty advising event will have their "Major Elective Approval" requirement marked as complete by a Computer Science staff advisor. Effective Winter 2022, students should not complete or submit an approval form, instead students must attend a department faculty advising event.
The department usually hosts a faculty advising event every quarter: in Fall and Winter quarters students can meet one-on-one with faculty at the Speed Advising event, and in Spring quarter students can learn from faculty about the CS courses that are elective options for the major at the Major Electives Info Session event (view the Major Elective slide show here and see the recording of the Spring 2024 Major Elective information session here.
Depending on their GEAR major year, CS students must take either 28 units (GEAR year 2019-20 and prior years) or 32 units (GEAR years 2020-21, 2021-22, 2022-23, 2023-24) of upper-division major field electives. At least 8 units of these electives must be Computer Science courses. The required courses in the upper-division major do not count towards these electives. All upper-division elective courses must be taken for a letter grade.
Academic Advising
Undergraduate Advising
The staff advisors are here to help and support our CS majors through their studies and answer questions related to the CS major. We are available for appointments in-person, and encourage our students to book an appointment to guarantee that we are available and prepared to answer your questions related to your degree progress and requirements.
Staff hours are Monday through Friday 9am-12pm and 1-4pm and we are available by email at cs-undergrad@ucsb.edu, or by appointment at https://calendly.com/ucsb-cs-dept/ or clicking the button below:
Faculty Undergraduate Advisors
CS majors may contact their faculty class advisor for questions regarding their own faculty experiences, undergraduate research, graduate school, jobs in industry. Faculty members are not expected to answer questions about department petitions or degree requirements. Please see below for the contact links of the current faculty class advisors:
Jonathan Balkind Faculty contact for class of 2028
Tobias Höllerer Faculty contact for class of 2027
Ziad Matni Faculty contact for class of 2026
Subhash Suri Faculty contact for class of 2025
