UC Schools Ranked: A Guide to the University of California System

The University of California (UC) system is the world's leading public university system. It has nine undergraduate campuses, each with distinct character and selectivity.

For an international applicant, the UC system has two important features:

1. It uses its own application platform (the UC Application), not the Common App.
2. The same application goes to multiple UC campuses simultaneously. You select which to apply to within one form.

The nine UC campuses

| Rank | Campus | Acceptance rate | Best known for | | --- | --- | --- | --- | | 1 | UC Berkeley | 11.2% | Computer Science, Engineering, Economics, public policy | | 2 | UCLA | 8.6% | Film, business, biology, social sciences | | 3 | UC San Diego | 24.7% | Biology, neuroscience, oceanography, computer science | | 4 | UC Davis | 36.2% | Agriculture, veterinary medicine, engineering | | 5 | UC Irvine | 21.0% | Computer science, biology, business | | 6 | UC Santa Barbara | 28.3% | Physics (Nobel-winning department), engineering, marine biology | | 7 | UC Santa Cruz | 49.7% | Marine biology, environmental sciences, computer science | | 8 | UC Riverside | 69.4% | Engineering, biology, business | | 9 | UC Merced | 88.7% | Newest UC; engineering, environmental sciences |

UC Berkeley sits among the top public research universities globally — competitive with most Ivies for engineering and computer science. UCLA is similarly elite, with particular strengths in film, performing arts, and life sciences.

UC Berkeley: the flagship

• Founded: 1868
• Undergraduate cohort: ~32,000
• Acceptance rate: 11.2%
• Strongest fields: Engineering, Computer Science, Mathematics, Economics, Physics, Chemistry, Public Policy

Berkeley is the original UC and its flagship. Many of its programmes rank in the global top 5 for their fields. The College of Engineering and the Haas School of Business are particularly competitive — admission rates for those colleges are tighter than the campus-wide rate.

UCLA: the other coast's media capital

• Founded: 1919
• Undergraduate cohort: ~32,000
• Acceptance rate: 8.6%
• Strongest fields: Film and Television, Theatre, Biology, Psychology, Economics, Mathematics

UCLA's School of Theater, Film, and Television is one of the best in the world. Its biology and life sciences departments are also exceptionally strong.

UC San Diego: the rising star

• Founded: 1960
• Undergraduate cohort: ~33,000
• Acceptance rate: 24.7%
• Strongest fields: Biology, Computer Science, Oceanography, Neuroscience, Engineering

UC San Diego has risen rapidly in international rankings over the past two decades. It has particular strengths in life sciences (especially given Scripps Institution of Oceanography is part of the campus) and computer science.

UC Davis: agriculture and beyond

• Founded: 1908
• Undergraduate cohort: ~32,000
• Acceptance rate: 36.2%
• Strongest fields: Agriculture, Veterinary Medicine, Engineering, Plant Sciences, Wine Studies

Davis is the global leader in agricultural and veterinary sciences.

UC Irvine: the engineering school

• Founded: 1965
• Undergraduate cohort: ~28,000
• Acceptance rate: 21.0%
• Strongest fields: Computer Science, Engineering, Biological Sciences, Business

UC Irvine has built strong technical programmes, particularly in computer science (Donald Bren School of Information and Computer Sciences).

UC Santa Barbara: the smallest top UC

• Founded: 1909
• Undergraduate cohort: ~24,000
• Acceptance rate: 28.3%
• Strongest fields: Physics, Engineering, Marine Biology, Environmental Sciences

UCSB's physics department has produced multiple Nobel Prize winners and is consistently top-10 globally.

UC Santa Cruz, UC Riverside, UC Merced

The remaining three are smaller, less selective, and less well-known internationally. They serve California's massive in-state demand and offer strong programmes in specific fields:

• UC Santa Cruz: Marine biology, environmental sciences, computer science
• UC Riverside: Engineering, business, social sciences
• UC Merced: Engineering, environmental sciences (newest UC, founded 2005)

For international applicants, these three are typically used as safety options on a UC application.

How the UC application works

Different from the Common App in three ways:

1. One form, multiple campuses. You can apply to up to 9 campuses with one fee per campus.
2. Personal Insight Questions. Instead of a single 650-word essay, the UC Application asks you to write four 350-word responses to "Personal Insight Questions" from a list of 8.
3. No Common App essay. Your UC application is read separately.

What predicts a UC offer

For Berkeley and UCLA, where acceptance rates are sub-10%:

1. Top-of-class GPA at a high school of known quality. UC has a 3.4 GPA minimum but real admits are 3.9+.
2. Strong test scores where they apply. UC went test-blind in 2020 and remains so — SAT/ACT scores are not considered.
3. Strong personal insight responses. The 350-word PIQ format rewards specific, concrete, voice-rich writing.
4. Demonstrated leadership and depth in extracurriculars.
5. For Berkeley CS or UCLA Engineering, strong demonstration of subject interest. Olympiads, research, projects.

The honest summary

Berkeley and UCLA are top-tier global universities — competitive with the best private universities in their respective fields. The other seven UCs are strong public universities, varying widely in selectivity.
