In the past, when gauging admission difficulty, people often only had a university’s overall acceptance rate to go by. But once you dig deeper, you realize that different majors at the same school can differ in difficulty by more than just a notch!
Now, with the official data released, the question of “how competitive it really is” finally has a definitive answer. More importantly, as one of the largest and most competitive public university systems in the U.S., UC sees record application numbers every year, and competition only intensifies. Understanding the real data early means getting a head start on your peers.
CheersYou（清柚教育） will combine the latest UC official data on:
✅ Overall acceptance rates across the nine campuses
✅ Real numbers for each college & popular major
✅ Competition levels across GPA ranges
to give you a one-stop overview of the “true difficulty map” of the nine UC campuses!
UC Overall Admission Difficulty Overview
The nine campuses exhibit a very clear “tiered competition” pattern in admission difficulty:
Source: UC
Tier 1: Top-Tier Battlefield
UCLA and UC Berkeley still hold the title of “hardest to get into,” with acceptance rates of about 9% and 11%, respectively. Not only do they attract massive applicant pools, but admitted students typically have GPAs clustered around 4.2—truly a battleground for high-scoring, hardcore achievers.
Tier 2: Moderately Competitive Core
This tier includes UCSD (27%), UCI (29%+), UCSB (33%+), and UCD (42%). While the overall difficulty is notably lower than the top two, the quality of admitted students remains high, and this is where most Chinese applicants concentrate.
Tier 3: High-Acceptance Friendly Zone
UCR (76%+), UCSC (66%), and UCM (91%) have significantly higher overall acceptance rates, offering more security for students with average backgrounds needing reliable safety options.
Next, let’s look at each campus’s major-specific admission data.
Detailed Admission Difficulty Breakdown by Campus
University of California, Berkeley (UCB)
Long known for its rigor in both admission and coursework, UC Berkeley’s major-level admission gaps are far wider than most imagine—the difficulty can differ by nearly ten times across programs.
According to official data, Computer Science, which for years held the “hardest to get into” crown, was unexpectedly overtaken this time by Public Health: due to the college slashing nearly half its enrollment spots, its acceptance rate plunged to around 2%, making it the toughest track to break into at the entire university.

Close behind are the two perennial kings of competition—CS and Business—both hovering around 4% acceptance rates, approaching Ivy League–level selectivity. Engineering, with the largest applicant pool (over 21,000), has an acceptance rate of about 8%, remaining fiercely competitive.
In contrast, Arts & Humanities emerges as Berkeley’s most accessible “window of opportunity,” with an acceptance rate of 23%. Life Sciences, Physical Sciences/Math, and Public Policy also generally have rates above 10%.
Looking at student profiles, the average GPA for Engineering, Business, and CS freshmen is typically concentrated between 4.20 and 4.30, making these true high-score clusters. In terms of enrollment yield, CS tops the campus at 67%, attesting to its allure.
A crucial reminder: Berkeley only considers a second-choice major during the waitlist conversion phase, and the yearly conversion rate fluctuates wildly. Additionally, although the school has relaxed internal transfer policies for EECS and CS, the requirements remain stringent, and the actual success rate is extremely low. Students with clear goals should absolutely apply directly to their intended major from the start.
University of California, Los Angeles (UCLA)
With its surging momentum in recent years, UCLA has firmly claimed the title of “the most difficult UC to get into”—its overall acceptance rate for Fall 2024 stood at just 8.97%. At the major level, competition gaps are equally wide.
Contrary to many expectations, UCLA’s most “hellish” major is not CS but Nursing: nearly 6,000 applicants competed for only 55 spots, yielding an acceptance rate below 1%. Yet once an offer is made, the enrollment rate soars to 73%, underscoring its powerful draw.

For Chinese students, the most commonly applied major that is truly the most cutthroat remains Computer Science, with a stable acceptance rate of about 4%. Engineering follows closely at around 6%, with applicant numbers continuing to climb—overall pressure has not eased.
Meanwhile, Social Sciences attracted the most applicants (23,884) but had an acceptance rate of only 9%, making it quite challenging. Life Sciences falls into a moderately competitive range (around 13%), while Physical Sciences/Math is relatively friendlier, with an acceptance rate nearing 15%—one of the rare “manageable tracks” at UCLA.
From the academic profile perspective, UCLA clearly favors high-scoring applicants, with admitted students’ GPAs concentrated in the 4.20–4.30 band. In Engineering and Physical Sciences/Math, many top applicants even boast GPAs of 4.32 and above.
Important note: UCLA is not particularly friendly toward Undeclared (undecided) majors, with the acceptance rate consistently hovering around 7%, which is no easier than applying to a specific major. In contrast, the School of Music actually has the highest acceptance rate campus-wide (around 24%), and transitioning from there to other undergraduate colleges is relatively manageable. For high-achieving students with musical talents, this indeed represents a viable “curve-entry” pathway worth serious consideration.
University of California, San Diego (UCSD)
Built on a foundation of STEM, UCSD appears relatively friendly overall, but when you drill down to the major level, competition clearly diverges, with STEM fields still being the primary battleground.
Fall 2024 data shows that Computer Science remains the toughest nut to crack, with an acceptance rate of about 13%. Following closely are Engineering (about 17%) and Business (about 18%), both demanding strong academic backgrounds and well-prepared materials.

Public Health (19%) and Social Sciences (24%) also fall into the moderate-to-high competition range, with Social Sciences attracting the largest applicant pool campus-wide, exceeding 25,000.
By contrast, Life Sciences, Physical Sciences/Math, and Arts & Humanities are noticeably more welcoming, with acceptance rates generally in the 30%–36% range. Moreover, UCSD is relatively lenient toward Undeclared (undeclared major) and interdisciplinary applicants.
Overall, UCSD remains a high-achiever’s arena, with admitted students’ average GPAs clustered between 4.10 and 4.28, and CS and Engineering seeing many 4.30+ scorers.
One critical point: UCSD has officially designated CS as a highly selective major, meaning internal transfers into CS are no longer accepted. Except for a few tracks, transferring into the College of Engineering is also extremely difficult, so students with clear goals must apply directly.
University of California, Davis (UCD)
Among the six most popular UC campuses, UCD has long been known for its “relatively gentle admissions.” Even with over 100,000 applicants, its overall acceptance rate held steady at 40%–42%, making it widely recognized as one of the friendlier schools in the TOP50.
However, once you break it down by major, UCD also exhibits clear tiered competition. Computer Science remains the toughest to enter, with an acceptance rate of about 17% and an enrollment yield of only 8%, indicating sustained competitive heat. Majors like Business, Engineering, Education, and Social Sciences, while boasting acceptance rates above 30%, still fall below the campus average, so don’t let your guard down when applying.

In contrast, Public Policy/Public Administration stands out as a “friendliness champion,” with an acceptance rate of 67% and an enrollment rate of 31%. Specializations in Life Sciences, Health Sciences, and Physical Sciences/Math also generally see acceptance rates of 50%–60%, making them excellent safe choices.
When it comes to academic profiles, UCD is also more inclusive overall, with admitted freshmen’s average GPAs ranging from 4.00 to 4.26, and some majors have even admitted students with GPAs in the 3.9+ range.
For strategy, CS and Engineering allow internal transfers, but you’ll need to plan early with an academic advisor; direct admission is still recommended. Those aiming for Business may consider Managerial Economics as a second-choice major to boost chances. Additionally, UCD’s waitlist conversion rate reaches 39%, representing a very worthwhile supplementary admission channel.
University of California, Irvine (UCI)
Within the UC system, UCI has always been considered relatively friendly toward international students. Among its 28.94% overall acceptance rate, the international student acceptance rate reached a striking 42.79%, notably higher than the 21.60% for in-state students—making it exceptionally welcoming for international applicants.
But at the major level, UCI’s competitive divide is equally pronounced. The most exclusive remains Nursing: nearly 6,000 applicants vied for only about 1% acceptance, closely tied to its ranking as a top nursing program in California with a 90% NCLEX-RN pass rate.
Source: UC
Business follows closely, with over 16,000 applicants and an acceptance rate around 12%–13%, actually harder to get into than many would assume for CS. In comparison, Computer Science (about 20%) and Engineering (about 28%) are relatively friendly choices within the UC landscape, while Physical Sciences/Math is a “hidden gem” with a 44% acceptance rate, ideal as a second major alongside CS or Engineering.
Strategic pointers: UCI admits strictly by major and places high importance on major fit; admissions officers even recommend using their Major Quiz to clarify direction. The good news is that UCI’s internal transfer policy is relatively flexible, with lower hurdles for switching into CS and Engineering. Business allows transfers but requires re-applying through the admissions process.
University of California, Santa Barbara (UCSB)
UCSB is also very international-friendly, with an international student acceptance rate of 48.14%, and out-of-state students faring even better at 54.78%, significantly above the 32.09% for in-state students.
Looking at the major distribution, Computer Science remains the most challenging, with an acceptance rate around 17%, followed by Engineering. However, CS’s enrollment yield is only 12%; instead, Business leads with a 26% yield, making it the major with the highest enrollment rate.
Source: UC
Social Sciences is the most popular area, with over 30,000 applicants and an acceptance rate still at 33%. Physical Sciences/Math and Life Sciences, on the other hand, are “friendliness champions,” with acceptance rates generally between 40% and 50%—very solid STEM choices.
Regarding academic profiles, UCSB has clearly favored high-scoring applicants in recent years, with admitted freshmen averaging GPAs of 4.13–4.29, and about 25% of Engineering admits near-perfect scores.
During the application review, admissions officers pay close attention to how applicants have utilized their high school resources and personal background, focusing on context.
UCM/UCR/UCSC
Within UC’s high-acceptance-rate tier, UCM, UCR, and UCSC serve a very clear role—safe, reliable, and high tolerance. Overall, UCR’s acceptance rate is above 75%, UCSC around 66%, and UCM exceeds 90%+, making them the most “safety-oriented” campuses in the entire UC system.

Even when examined at the major level, the overall rhythm across these three campuses is noticeably gentler: while CS, Engineering, and similar popular tracks are still comparatively more competitive, their acceptance rates are markedly higher than those at UCLA, UCB, UCSD, and others. Fields like Life Sciences, Social Sciences, Education, and Arts & Humanities offer very substantial admission availability.
In terms of academic profiles, this tier is also more inclusive regarding GPA, with many programs admitting students in the 3.8–4.0+ range, making them very friendly to applicants whose backgrounds are not fully “maxed out.”
It’s worth noting that all three schools value major fit and academic continuity, but they are relatively flexible regarding internal transfers, especially UCSC, which still retains some maneuvering room in engineering and certain STEM fields.
How to Strategically Select UC Campuses and Majors
After reviewing the authentic admission data from the nine UC campuses, one conclusion is clear: UC’s difficulty is truly determined not by “school prestige,” but by “what major you choose.”
Application strategies must be tailored to different student profiles:
High Achievers (GPA 4.2+, Strong STEM Background)
You can confidently target highly competitive programs like CS, Engineering, or Business at UCLA, UCB, and UCSD. However, be sure to also apply to relatively friendlier STEM or foundational majors at UCSB or UCI as a buffer to avoid the risk of “all reach, no safety.”
Solid High-Score Mainstream Candidates (GPA 4.0–4.2)
It’s more advisable to focus on UCSD, UCI, UCSB, and UCD as primary targets, emphasizing “value majors” like Physical Sciences/Math, Life Sciences, Managerial Economics, or Public Policy, which are more realistic than stubbornly fixating on CS.
Safety-First Applicants (GPA 3.8–4.0+)
Prioritize UCD, UCSB, along with UCSC, UCR, and UCM. Avoid the top-tier hyper-competitive tracks and focus on securing admission into a UC campus first, then explore internal resources and growth opportunities later.
The data from recent years clearly shows that while the overall difficulty of UC admissions has changed little, the differentiation between majors is continually widening.
Popular tracks like CS, Engineering, Business, and Nursing are steadily tightening, while many foundational and applied programs still maintain stable windows of opportunity. Therefore, what applicants should truly focus on is not “whether they can get into a prestigious school,” but whether they have chosen the right major early enough.
Starting preparation now offers the greatest advantage: control. You have time to build a clear, logical thread connecting your coursework, activities, and long-term efforts to your target major, rather than gambling on luck at application time. Ultimately, when you submit your materials, it’s not just about scores, but about whether you truly stand firm within your chosen field.
UC never lacks outstanding students, but it consistently favors applicants with clear direction and stable paths. Plan early, prepare thoroughly, and may everyone receive their dream school offer and successfully land ashore!
