Does Your Major Matter for UC Admissions?

Does Your Major Matter for UC Admissions?

It depends on the campus and the college inside it. At UCLA, "For The College, the applicant's major is not considered during the review process." At Berkeley, your first-choice major is an admission factor in five colleges and schools, and Irvine says major choice "is a factor in admission for all majors." Merced says it is a factor for none.

So the popular plan, "apply to a less competitive major and switch later", needs a campus-by-campus check before you rely on it. Our view: at Berkeley and UCLA, the backdoor is mostly a myth. In UCLA's College there is no door to go through, because the major is not read. In Berkeley's College of Letters and Science you get one later attempt at a high-demand major, with a required backup. And at Berkeley Haas, a "no" from the business program is a "no" from Berkeley.

Every UC page quoted below was checked on October 30, 2026, for the fall 2027 application, which you file between October 1 and November 30, 2026. The campus rules come from UC's Quick Reference Guide to UC Admissions (August 2026). The alternate-major rules are on a separate page: UC selective majors and alternate majors by campus.

Short answer by campus

UC's guide answers "For which programs is the intended major a factor in admission?" for each campus. Shortened, with the key words quoted:

Two campuses look the same but are not. Merced and Santa Cruz both say the major does not change your review. Santa Cruz still calls its Computer Science majors "selective" and says "Students interested in Computer Science must apply to the major."

UCLA: the College vs the professional schools

UCLA publishes admit rates by school and by major. Its fall 2025 first-year profile reports 145,085 applicants and 13,659 admits overall.

Inside the College, UCLA's profile by major gives four division rates: Humanities 9.9%, Life Sciences 11%, Physical Sciences 14% and Social Sciences 9.3%. Right under that table, UCLA says the major "is not considered during the review process."

Our reading: the division rates differ because different students apply to them, not because the division was read. Picking a College major you think is "easier" changes nothing in the review. UCLA's Choosing a Major page says the same in plainer words: "your choice of major will neither help nor hurt your prospects for admission."

Two UCLA rules matter more than the rates:

• One major only. "UCLA reviews first-year applicants for one major only." Your alternate is ignored there.
• Some College majors start as pre-majors. UCLA's majors list marks Business Economics, Economics and others with a note: "Applicants are admitted to pre-major status until prerequisites are satisfactorily completed."

Berkeley: colleges, CDSS and the high-demand policy

At Berkeley the college you pick is the decision. Computer Science sits in the College of Computing, Data Science, and Society (CDSS), with Data Science and Statistics, according to Berkeley's majors page. UC's guide lists CDSS among the colleges where "first-choice major is a factor." Pages that still describe Berkeley CS as a Letters and Science major describe an old route. The CS-specific choices are in UC computer science admission at Berkeley, UCLA and UCSD.

Letters and Science has its own rule for high-demand majors, in force for first-years "applying to UC Berkeley Letters & Science (L&S) for fall 2023 and after" (L&S high-demand policy):

"If admitted to UC Berkeley L&S, they will be guaranteed a spot in the major they selected, subject to completing the prerequisites, maintaining good academic standing in L&S, and filing a declaration form."

If you do not pick it on the application, "Students will have one opportunity to apply for a high-demand major, and will be required to have an alternate plan to declare a non-high-demand major as a back-up." Berkeley adds: "The opportunities for being admitted to a high-demand major after enrollment are extremely limited." The page does not list which majors are high-demand; it links to an L&S FAQ.

Berkeley's application FAQ is honest about switching after you enrol: "In most circumstances, it is possible to change your major. However, higher-demand majors such as Engineering, or social sciences, may be more difficult to transfer. It is easier to transfer majors in the same college."

At Haas, there is no switching plan at all for the Spieker business program: "If you're not admitted to the business major (a.k.a. the Spieker Undergraduate Business Program) as a first-year applicant, you will not be admitted to UC Berkeley." The three Haas routes are compared in the Berkeley Haas undergraduate application guide.

Undeclared: when it is neutral and when it hurts

UC's guide says applying Undeclared "does not affect admission" at Berkeley, Davis, Merced, Riverside, San Diego, Santa Barbara and Santa Cruz, and "does not negatively affect admission" at Irvine. Berkeley's FAQ: "Applying undeclared does not impact your chances of admission." The exceptions are in the details:

For non-UC colleges, the same decision is worked through in should you apply undecided.

• UCLA: "selecting Undeclared-Engineering does impact admission due to space limitations." In fall 2025, Undeclared — Engineering and Applied Science admitted 6.4% of 2,373 applicants.
• San Diego: "applicants interested in highly selective majors are advised to apply directly to the major."
• Santa Cruz: Computer Science applicants "must apply to the major."
• Santa Barbara: Undeclared exists only in Letters and Science, not in Creative Studies or Engineering, "as movement between colleges later may not be allowed."
• Riverside: no Undeclared option in the Bourns College of Engineering, School of Business, School of Education and School of Public Policy.
• Berkeley: Undeclared is neutral, but if you want a high-demand L&S major, Engineering or Haas, the guide says to "select those majors as their first choice."

The countercase: if you really do not know what you want, Undeclared in a college where the major is not read is the safest choice UC offers. It costs nothing at admission. The cost comes later, and only if your eventual major is capped.

A four-question decision procedure

Ask these for each campus. If any answer is "yes", list the major you actually want first.

1. Is the major read in this college? UCLA College: no. Berkeley CDSS, Engineering, Chemistry, Environmental Design, Haas: yes. Irvine: always.
2. Is it hard to switch in after enrolling? Berkeley's L&S high-demand majors: one attempt, a backup required. UCLA: changing majors "WITHIN the College is not allowed" after you apply.
3. Is the program all-or-nothing? Berkeley's Spieker program: a "no" means no Berkeley offer at all.
4. Do your personal insight answers support the major you list? Your four personal insight answers go to every campus you apply to, and none of the eight questions is a "why this major" prompt, so your evidence lives in the answers you choose. Question 6, on an academic subject, is the usual home. The choose-four guide tests where your evidence fits.

Constructed example: business or economics at UCLA and Berkeley

Constructed example, written by us, not a real applicant's choices. Context (invented): Daniel, a California senior, wants business and is choosing what to list at UCLA and Berkeley.

• UCLA. UCLA has no undergraduate business school on its majors list. Business Economics is a College major. Because the College does not read the major, listing Business Economics instead of Undeclared neither helps nor hurts him. It does start him as a pre-major, so he should read the prerequisites before he enrols.
• Berkeley, option A: Spieker first. This is the only way to be reviewed for Haas as a first-year. If Haas says no, he has no Berkeley offer. He must also finish the Haas supplemental essay and video by early January.
• Berkeley, option B: Economics in Letters and Science. If Economics is one of L&S's high-demand majors (he must check the L&S FAQ for the current list), selecting it on the application guarantees it if he is admitted, subject to prerequisites. He gives up a first-year shot at Haas.

Daniel's real decision is not "which major is easier." It is "how much do I want Berkeley if it is not Haas?" If the answer is "a lot," option B fits. If he would only attend Berkeley for Haas, option A fits. Neither choice changes anything at UCLA.

Out-of-state and international applicants

The major rules above are the same for every applicant. What changes is the minimum: UC's guide sets "a minimum grade point average of 3.0 for California residents, 3.4 for nonresidents." For what nonresident review looks like, see UC for out-of-state applicants.

Questions about UC major choice

Is it easier to get into UCLA as undeclared?

Not in the College. UC's guide says applying Undeclared there "does not affect admission," and the major is not considered at all. In Engineering, Undeclared-Engineering "does impact admission due to space limitations."

Should I apply to a less competitive major at UCLA to get in?

It does nothing in the College, because the major is not read. In the professional schools, you are reviewed only for the major you list, and changing majors into those schools after you apply closes on January 1 (Engineering) or December 1 (the arts, music, nursing and film schools).

Does major matter for UC Berkeley admissions?

Yes in Chemistry, CDSS, Engineering, Environmental Design and Haas. In Letters and Science, the major you list matters for high-demand majors, because listing one is how you are guaranteed it.

Can I change my UC major after submitting?

Sometimes. UCLA lets you move into the College until January 1 but not between College majors. San Diego takes changes in its Applicant Portal until January 31. Berkeley takes requests through its Contact Us form and "No new major changes will be considered after January." The full list is on the selective and alternate majors page.

It reads whether you name the subject and the question that holds you, show how you followed it, and say what you came to understand. If your case for the major rests on something outside class, the UC PIQ standout rubric for Question 8 reads whether you give one clear answer and back it with your own experience. Both start from the UC PIQ review page.
