What the University of California system is

The University of California (UC) is a public university system made up of several undergraduate campuses across the state of California, each with its own location, character, and academic strengths. Well-known campuses include Berkeley, Los Angeles (UCLA), San Diego, Davis, Irvine, Santa Barbara, Santa Cruz, Riverside, and Merced.

The campuses share one system and one admissions application, but each makes its own admission decisions. Being admitted to one UC campus does not mean you are admitted to another — every campus you apply to reviews your application separately.

This guide explains how the system and its shared application work. The exact list of campuses, requirements, and deadlines can change each cycle, so always confirm the current details on the official UC Admissions website before you apply.

One application for multiple campuses

UC uses its own single online application — not the Common Application. You complete one UC application and can select multiple campuses within it, paying an application fee per campus you add. This lets you reach several UC campuses with one set of information.

Because the application is shared, you enter your courses, grades, activities, and personal-insight responses once. Each campus you select then receives and reviews that same application under its own standards.

The filing period, the number of campuses you may apply to, and the fee amounts are set by UC and can change. Verify the current filing dates and fees on the official UC Admissions site before you start, rather than relying on figures from any other source.

Personal-insight questions instead of one big essay

Rather than a single long personal statement, the UC application asks you to respond to a set of shorter personal-insight questions. You choose a defined number from a published list and answer each within a word limit set by UC.

These responses are your space to show who you are beyond grades and test data — your background, challenges, interests, and what you would bring to a campus. There is no single 'right' topic, and UC states that all of the questions are given equal consideration.

Write in your own words and answer honestly. The number of questions you must answer, the published list, and the word limit can be updated, so confirm the current personal-insight instructions on the official UC application before you write.

How applications are reviewed

UC campuses use a comprehensive review of your application that looks at your academic record alongside a range of broader factors, rather than a single cut-off number. The specific factors and how they are weighed are published by UC and can differ by campus.

UC publishes its own minimum eligibility requirements for California residents and for applicants from outside California, including coursework and academic expectations. International applicants are reviewed under UC's stated criteria and typically also provide proof of English proficiency.

Because requirements and review practices are set by UC and updated over time, check the official UC Admissions pages for the current eligibility rules, required coursework, and any testing or English-proficiency policies. Treat any specific figure you see elsewhere as something to confirm against UC's own pages.

Frequently asked questions

Does the University of California use the Common App?

No. UC has its own dedicated application. You apply to UC campuses through the UC application rather than the Common Application or Coalition Application. Confirm the current process on the official UC Admissions website.

If I am admitted to one UC campus, am I admitted to all of them?

No. Each campus you select reviews your application and decides independently. You can be admitted to one campus and not another, even with the same application. Apply to each campus you are genuinely interested in. No application strategy can guarantee admission to any campus.

How many personal-insight questions do I have to answer?

UC asks you to answer a set number chosen from a published list, each within a word limit. The exact count and word limit are set by UC and can change — check the current personal-insight instructions on the official UC application before writing rather than assuming a number.

Can international students apply through the UC application?

Yes. International applicants use the same UC application and are reviewed under UC's stated criteria, usually including English-proficiency requirements. Verify the current international requirements on the official UC Admissions site.

Is there a separate fee for each campus?

UC charges an application fee for each campus you add to your application, with the amounts set by UC. Fee-waiver eligibility may exist for some applicants. Confirm the current fees and any waivers on the official UC Admissions website.
