Cornell's Biological Sciences major sits within the College of Agriculture and Life Sciences (CALS), one of Cornell's statutory, land-grant colleges — and one of the broadest, most research-intensive undergraduate biology programs at any Ivy League university. For international students, Biology at Cornell offers something distinctive among the Ivies: a genuinely large, well-resourced life-sciences department backed by Cornell's land-grant research mission, in a university that markets itself, unusually among its peers, as a place "where any person can find instruction in any study." This guide covers what the major costs as part of a Cornell undergraduate degree, how Cornell's college-specific application process works for Biology, the English-proficiency bar, and what graduates go on to do — using Cornell's own published data wherever it exists and flagging clearly where a figure is a broader university-wide or general estimate.
Acceptance Rate: What We Actually Know
Cornell's dataset confirms Biology as one of Cornell's popular undergraduate programs, taught through the College of Agriculture and Life Sciences (the BS in Biological Sciences is listed explicitly in Cornell's course catalog under CALS). As with most Cornell majors, though, there is no Biology-specific acceptance rate published separately from the university-wide figure.
What's worth knowing:
- Cornell's overall undergraduate acceptance rate is 8.4% for the Class of 2029 (roughly 6,077 admits from about 72,500 applications) — this is Cornell's own published aggregate figure, not a Biology-specific number.
- Early Decision ran considerably higher (18.8%) than Regular Decision (6.7%) for the same class, per Cornell's own published data — a meaningful gap that applies regardless of intended major.
- Cornell's dataset explicitly flags that selectivity "varies considerably by undergraduate college," and since applicants apply directly to one of Cornell's seven undergraduate colleges (Biology sits within CALS, a statutory college), CALS's admit rate is not the same as, and not directly interchangeable with, Cornell's more selective endowed colleges like Engineering or the SC Johnson College of Business.
- Because CALS is one of Cornell's land-grant statutory colleges, it also has different structural admissions dynamics than Cornell's private endowed colleges — historically, statutory colleges have sometimes run somewhat less selective than Cornell's most competitive endowed programs, though this is general context rather than a specific confirmed CALS or Biology admit-rate figure, and applicants should not assume this makes Biology an "easy" path into Cornell.
Bottom line: Cornell overall is highly selective at 8.4%, and Biology's actual selectivity within CALS is not separately published — treat any specific major-level percentage you encounter online as an unverified estimate rather than an official Cornell number.
Tuition and Fees
Cornell's tuition structure is genuinely more complex than most Ivy peers because it mixes privately endowed colleges with state-supported statutory colleges — and CALS, which houses Biology, is one of the statutory colleges. Critically, this in-state discount does not apply to international students.
| Cost Item | Amount (USD, 2026-27) | Detail |
|---|---|---|
| Tuition (international students, all colleges including CALS) | $73,946/year | Cornell's endowed-college rate, which applies to essentially all international undergraduates regardless of college |
| Living expenses | $25,788/year | Cornell's own published estimate; includes room, board, and other personal costs |
| Total cost of attendance | $99,734/year | Cornell's own published on-campus estimate, before financial aid |
| Application fee | $85 | Common Application/Coalition Application fee |
New York State residents in CALS pay a meaningfully lower published tuition rate as part of Cornell's land-grant mission, but international students — regardless of which of Cornell's seven colleges they attend, including the statutory CALS — generally pay the same endowed-college rate shown above. Cornell states a need-blind, full-need financial aid policy that its own materials describe as extending to international applicants as well as domestic ones, which is worth confirming directly given how much this specific policy area shifts across admissions cycles industry-wide, and how it sets Cornell apart from peer Ivies like Columbia that remain need-aware for international undergraduates.
Admission Requirements
| Requirement | Detail |
|---|---|
| Application platform | Common Application or Coalition Application, plus Cornell's CALS-specific supplement |
| College-specific application | Applicants apply directly to the College of Agriculture and Life Sciences, not to Cornell broadly — CALS has its own supplemental essay prompts |
| Standardized tests | SAT/ACT test-optional; policy is reviewed cycle-to-cycle, so confirm current status |
| Letters of recommendation | Secondary School Report and counselor recommendation, plus at least one teacher recommendation letter |
| Transcripts | Midyear School Report and Final School Report/official transcript required |
| English proficiency | Required for applicants whose first language isn't English and who don't qualify for an exemption |
| Application fee | $85 |
Cornell's dataset does not itemize Biology-specific prerequisite coursework, but as a CALS science major, a strong secondary-school record in biology, chemistry, and math is standard expected preparation, consistent with how Cornell's college-specific application model generally evaluates applicants against the specific curriculum of their target college rather than a generic university-wide standard.
How to Get In
Cornell's dataset flags writing — specifically, college-fit writing — as the single highest-leverage part of the application, and this is especially true for CALS/Biology applicants given how distinct a statutory land-grant college's mission and curriculum are from Cornell's endowed colleges:
-
Write your CALS supplement around genuine interest in life sciences and Cornell's land-grant mission, not a generic "I love biology" statement. Cornell's dataset is explicit that a generic personal statement performs worse here than at universities with a single unified application — CALS reviewers are specifically checking for fit with the college's applied, research- and agriculture-adjacent life-sciences identity, not just biology as an abstract subject.
-
Show academic rigor in the sciences specifically. With SAT/ACT policy varying by cycle, a demanding course load in biology, chemistry, and math — and strong grades within it — is a consistently weighted signal across Cornell's colleges.
-
Name specific CALS resources or faculty research if you can. Cornell's college-specific application model rewards applicants who can connect their own interests to something concrete about that particular college, rather than writing about "Cornell" generically.
-
Understand the Early Decision advantage, but only apply ED if Cornell/CALS is genuinely your first choice — Cornell's ED rate (18.8%) ran nearly three times Regular Decision's (6.7%) for the Class of 2029, but ED is binding, so it should reflect real certainty, not just admissions strategy.
-
Clear your English proficiency score well ahead of the deadline. Cornell's IELTS 7.5/TOEFL 100 requirement sits above many peer universities' minimums, and international applicants who clear it comfortably on Reading and Listening sometimes underprepare Writing specifically — a real risk given how closely Cornell reads its college-specific supplemental essays for genuine interest.
English Proficiency Requirement (IELTS/TOEFL)
Cornell's published undergraduate minimums, which apply to Biology/CALS applicants the same as any other Cornell college: IELTS Academic 7.5, TOEFL iBT 100 (for tests before January 2026) or 5.0 on ETS's new 1–6 CEFR-aligned scale (5.5 recommended, for tests from January 2026 onward), or Duolingo English Test 130. Cambridge English C1 Advanced/C2 Proficiency is separately accepted with a minimum score of 191. Waivers apply if English is your native language or has been the primary language of instruction throughout secondary school. Cornell does not offer conditional admission for scores below the threshold.

Career Outcomes
Cornell's dataset does not publish a Biology-specific employment rate, graduate/professional school placement rate, or average starting salary — consistent with a major whose graduates split across medical school, graduate school, and direct industry entry rather than one uniform career path.
Cornell's published university-wide recruiter list gives a general (not Biology-specific) signal: Google, J.P. Morgan, Goldman Sachs, McKinsey & Company, Amazon, and Deloitte — though, similar to most Ivy-wide recruiter lists, these names skew toward tech, finance, and consulting rather than life-sciences-specific employers, so they should be read as a general Cornell recruiting signal rather than representative of where Biology graduates specifically land.
Based on general knowledge of Biological Sciences program outcomes at research-intensive land-grant institutions, rather than a Cornell-published statistic, Biology graduates commonly pursue:
- Medical school and other health professional programs (dental, veterinary — notably, Cornell also operates its own College of Veterinary Medicine, giving CALS Biology students unusually direct exposure to a vet-med pathway relative to most peer universities' biology programs)
- PhD programs in biology, ecology, biomedical sciences, or related fields, drawing on CALS's research strength and Cornell's broader life-sciences faculty
- Agricultural, environmental, and biotech industry roles, reflecting CALS's applied land-grant mission alongside pure biological research
- Public health and policy roles, particularly for students who combine Biology coursework with CALS's applied life-sciences and policy-adjacent offerings
As with most Biology-type majors, there's no single "average starting salary" figure that meaningfully represents the degree, since outcomes fork heavily by whether a graduate goes to medical/professional school, a PhD program, or directly into industry.
FAQ
Does Cornell publish an acceptance rate specifically for Biology? No. Cornell publishes an overall undergraduate acceptance rate (8.4% for the Class of 2029) but does not break this down by major or, in most public reporting, by individual college. Cornell's own data flags that selectivity varies considerably by undergraduate college, so the 8.4% headline should not be assumed to equal CALS or Biology's specific admit rate.
Do I apply to Cornell as a whole, or specifically to CALS for Biology? You apply directly to the College of Agriculture and Life Sciences, one of Cornell's seven distinct undergraduate colleges, with its own supplemental essays — you cannot apply to Cornell generally and be assigned a college later.
Does the in-state tuition discount for CALS apply to international students? No. New York State residents pay a lower published tuition rate in CALS and Cornell's other statutory colleges, but this discount does not apply to international students, who generally pay Cornell's endowed-college rate ($73,946/year for 2026-27) regardless of which college they attend.
What IELTS or TOEFL score do I need for Cornell as an undergraduate? IELTS Academic 7.5, TOEFL iBT 100 (pre-January 2026 scale) or 5.0 on ETS's new scale, or Duolingo 130. See our full Cornell IELTS and TOEFL guides for section-level detail.
Is Cornell need-blind for international Biology applicants? Cornell's official financial aid materials describe its need-blind, full-need policy as extending to international undergraduate applicants generally, which would include CALS/Biology applicants — though this is an area that shifts across admissions cycles industry-wide, so confirm the current-cycle policy directly before relying on it.
Is Cornell's Biology program a good pre-med or pre-vet path? General knowledge suggests yes — CALS's Biological Sciences major covers strong pre-med-relevant content, and Cornell's own College of Veterinary Medicine gives Biology students at Cornell somewhat more direct exposure to a vet-med pathway than most peer universities offer, though this is contextual guidance rather than a Cornell-published placement statistic.
