UC Berkeley Biology Major Acceptance Rate

UC Berkeley is highly selective overall, with an acceptance rate of about 11% for Fall 2024 freshman applicants. However, when we focus on the Life Sciences discipline—which includes biology, pre-med, and related majors—the admit rate was 16%. Out of 20,179 applicants, 3,302 were admitted, and 1,332 ultimately enrolled, yielding about 40%.

At first glance, this 16% admit rate seems slightly less selective than UC Berkeley’s overall rate. But the numbers tell a deeper story. Life Sciences attracts a massive applicant pool of academically elite students, many aiming for medical school or high-level research.

The middle 50% GPA range for admitted students was 4.17–4.30, and for enrolled students, it remained nearly identical at 4.13–4.28. This narrow spread highlights how consistently strong the applicant pool is. Essentially, most successful candidates were near the top of their high school class.

In other words, while UC Berkeley admits a slightly larger proportion of Life Sciences applicants compared to the campus average, the bar for academic preparation is extremely high. Students can’t rely on GPA alone.

Given this competitive environment, strong grades and coursework are necessary but not enough on their own. Selection is not based solely on grades or test scores. Instead, UC Berkeley evaluates applicants through a holistic review process.

Admissions officers look at the full picture of a student’s academic record, personal insight questions, extracurricular activities, and context. The goal is to identify students who will contribute meaningfully to Berkeley’s educational and cultural community.

The UC Berkeley Biology major acceptance rate is highly competitive in practice. Applicants must demonstrate academic strength and evidence of curiosity, initiative, and persistence in scientific exploration. Many successful applicants highlight research internships, lab work, or leadership in science-related clubs to strengthen their profiles.

UC Berkeley Biology Major Requirements

Succeeding in UC Berkeley Biology requires careful academic planning. The program is known for its rigor, and you must complete a series of prerequisites before officially declaring your major. These requirements are divided into lower-division and upper-division coursework.

Lower-division requirements

All biology majors at UC Berkeley start with a common foundation in science and math. You’ll need to complete the following minimum requirements:

Key notes:

• IB majors can take the Math 16A/16B sequence (applied calculus), unlike MCB and CNR majors, that require Math 10 or Math 1.
• Students can choose between Physics 7 or Physics 8 series, depending on their background and career goals (Physics 7 is more calculus-heavy, Physics 8 is algebra/trig-based).
• All majors require General Biology (Bio 1A/1B) and Chemistry with labs.
• AP credits may partially satisfy some requirements, but most biology majors strongly recommend completing coursework at Berkeley for better preparation.

These classes are intensive and often considered “weeder” courses because they test whether students are prepared for the demands of a biology degree. To remain competitive for declaring a major—and for future opportunities like medical or graduate school—you’ll need to maintain strong grades in these prerequisites.

UC Berkeley Biology major transfer requirements

If you’re applying as a transfer student to study UC Berkeley Biology, you’ll need to meet the general admission requirements for the College of Letters and Science (L&S), effective for the Fall 2025 application cycle and beyond. These include:
