4. Bachelor of Arts in Computer Science (BA CS): A flexible degree option allowing students to pair rigorous core computer science coursework with substantial study in a secondary discipline outside of engineering (such as economics, cognitive science, or digital arts).

Graduate Programs (MS and PhD)

At the graduate level, UCSD CSE delivers Master of Science (MS) degrees in Computer Science and Computer Engineering (offering both thesis and comprehensive examination tracks) alongside a Research PhD program. Graduate specialization areas include Machine Learning and Vision, Cryptography and Security, Programming Languages, Database Systems, Computer Systems and Networks, Human-Computer Interaction (HCI), and Quantum Computing.

Navigating the 2026 UCSD CSE Selective Major Admissions Process

Admission to UCSD CSE at the undergraduate level operates under a Selective Major (formerly designated as "capped major") status due to exceptional student demand and faculty capacity constraints.

Freshman Direct Admission Strategy

For prospective freshmen applying for entry, declaring a CSE major (BS CS, BS CE, or BS CS/Bioinformatics) as their primary choice on the UC Application is essential.

• Direct Admission Mandate: Applicants must select a CSE program as their primary major option. If direct admission is not granted upon initial admission to UC San Diego, students are placed into an alternate non-selective major or undeclared status.
• Internal Major Switching Limitations: UCSD enforces strict policies regarding switching into CSE as a continuing student. Internal transfer capacity into CSE for students admitted under alternate majors is extremely limited and governed by a selective application process that requires high prerequisite GPAs and a randomized screening matrix. Admitted applicants should not matriculate under the assumption that they can easily switch into CSE later.

California Community College (CCC) and Transfer Pathways
