Natural Sciences is the University of Cambridge's largest and most flexible undergraduate course, letting students study across Physics, Chemistry, Biology, Genetics, Earth Sciences, and more before specializing, rather than committing to a single named science degree from day one. Run jointly across Cambridge's School of the Physical Sciences and School of the Biological Sciences, it draws applicants who want serious scientific breadth alongside Cambridge's collegiate system and small-group "supervision" teaching. For applicants comparing Cambridge Natural Sciences to Oxford's separate single-subject science degrees, or to broad US science majors, the pitch is genuine first-year flexibility across disciplines, backed by a university that has produced foundational work from the structure of DNA to the laws of motion.
This guide walks through exactly what it takes to get into Cambridge's Natural Sciences course: acceptance rate realities, cost, requirements, English-test rules, and what graduates go on to do.
Acceptance Rate
Cambridge does not publish a Natural Sciences-specific acceptance rate. What we know, grounded in Cambridge's own published data:
- Cambridge's overall undergraduate success rate was approximately 16% for the 2025 cycle (3,669 places accepted from 22,513 applications), though this masks large course-by-course variation.
- Cambridge has separately reported an international-applicant success rate closer to 11%, a more relevant benchmark for most readers of this guide than the blended 16% figure.
- Natural Sciences is Cambridge's largest single course by intake, and Cambridge's own commentary notes that Computer Science runs considerably more selective than the university average while some Arts and Humanities courses run less so; Natural Sciences is not singled out either way in Cambridge's published data, so it should be treated as sitting close to the university-wide band rather than at either selectivity extreme.
Bottom line: treat 16% (or 11% for international applicants specifically) as an honest university-wide proxy, not a Natural Sciences-specific figure. Cambridge does not publish enough course-level detail to say precisely where Natural Sciences sits relative to that average.
Fees and Cost of Attendance
Cambridge does not publish one flat undergraduate tuition figure; STEM subjects, including Natural Sciences, sit in a higher fee band than most Arts, Humanities, and Social Science courses. Approximate figures (2026-27, converted from GBP at roughly 1 GBP = 1.34 USD):
| Cost Item | Amount (USD/year) |
|---|---|
| Home (UK-domiciled) tuition | $13,119 |
| Overseas/international tuition (Natural Sciences Band 4 subject fee, GBP 44,214) | ~$59,247 |
| Average College fee (all 31 colleges) | ~$17,798 |
| Living expenses (Cambridge's own budget guidance) | $16,040 |
| Estimated total cost of attendance (international, Natural Sciences) | ~$93,085 |
This Natural Sciences-specific figure runs meaningfully higher than Cambridge's blended average across all subjects (which uses the lower Band 1 fee common to Economics, Law, and History), since STEM courses sit in Cambridge's higher fee bands. The UCAS application fee is a separate GBP 28.50 (~$38), covering up to five course choices, paid to UCAS rather than directly to Cambridge.
Admission Requirements
Cambridge Natural Sciences admission runs through UCAS, Cambridge's own supplementary "My Cambridge Application" (MCA) form, and course-specific testing. Based on Cambridge's published requirements:
- UCAS application and personal statement, submitted by the unusually early 15 October deadline
- Academic reference from school/college, plus the MCA supplementary form
- Predicted or achieved grades: typical conditional offers cluster around A*A*A at A-Level or 40-42 points at IB with specific Higher Level subject scores (commonly 776), though exact thresholds are set course-by-course
- ESAT (Engineering and Science Admissions Test), required for Natural Sciences alongside Engineering, Chemical Engineering and Biotechnology, and Veterinary Medicine
- IELTS Academic (or Cambridge English C1 Advanced/C2 Proficiency) for applicants who don't qualify for a waiver, since Cambridge no longer accepts TOEFL for undergraduate admissions
- Interviews with college Fellows, usually held in December for shortlisted candidates
Cambridge does not use a GPA scale; admission is assessed against A-Level, IB, or equivalent qualification grades. Interview invitations go out in November, and most decisions are released in mid-January.
How to Get Into Cambridge's Natural Sciences Course
-
Show breadth without diluting depth. Because Natural Sciences deliberately keeps students studying multiple science subjects in first year, your application should demonstrate genuine strength across more than one science, not just a single specialism, while still showing a clear sense of where you eventually want to focus.
-
Prepare seriously for the ESAT. Unlike a general personal statement, the ESAT is a timed, subject-specific written test, and Cambridge weighs it heavily for Natural Sciences applicants alongside predicted grades, so treat it as a distinct preparation track rather than an afterthought.
-
Use your personal statement to show scientific curiosity beyond the syllabus. Cambridge's supervision system is built around independent, self-directed academic exploration, so evidence of reading, projects, or research beyond your school curriculum (not just strong exam grades) helps you stand out.
-
Treat the interview as an academic conversation, not a test of memorized facts. Cambridge's college-based interviews are designed to see how you think under pressure and respond to new information in real time, a format most international secondary curricula do not train directly, so practising structured, spoken scientific reasoning matters as much as content knowledge.
-
Apply well ahead of the 15 October UCAS deadline. Because Cambridge's deadline is unusually early relative to most university systems, and applicants cannot apply to both Oxford and Cambridge in the same cycle, get your personal statement, reference, and MCA form finalized early rather than treating mid-October as a soft target.
English Proficiency Requirement (IELTS/TOEFL)
Cambridge Natural Sciences applicants follow Cambridge's standard undergraduate English-proficiency policy:
- IELTS: minimum 7.5 overall, normally with at least 7.0 in each of Listening, Reading, Writing, and Speaking
- TOEFL: not accepted for undergraduate applications; Cambridge undergraduate admissions relies on IELTS Academic or Cambridge English (C1 Advanced/C2 Proficiency) instead
- Interview readiness threshold: Cambridge recommends applicants hold at least IELTS 6.5 overall with no element below 6.0 at the point of application, with the full 7.5/7.0 requirement met before enrolment
- Waiver: generally available to nationals of, and long-term residents in, a UK Home Office-recognised majority English-speaking country, or those completing a full English-medium qualification

Career Outcomes
Cambridge does not publish outcomes data broken out specifically for Natural Sciences, but the university's broader undergraduate recruiting picture gives a useful proxy:
- Top recruiters (university-wide undergraduate): UK Civil Service, McKinsey & Company, Deloitte, PwC, Goldman Sachs, and NHS organisations
- Notable alumni with a strong Natural Sciences connection: Charles Darwin studied at Christ's College; James Watson and Francis Crick co-discovered the structure of DNA while working at Cambridge's Cavendish Laboratory; Stephen Hawking completed his PhD at Trinity Hall and spent most of his career at Cambridge
- Cambridge's Natural Sciences graduates go on to a wide range of paths, from academic and industrial research through to consulting, finance, and the civil service, reflecting the course's deliberately broad first-year structure rather than a single fixed career track
Cambridge does not publish a university-wide graduation rate, employment rate, or average starting salary broken out by course, so applicants should treat individual department and college-level outcomes data, where available, as the more precise signal.
FAQ
Does Cambridge publish a separate acceptance rate for Natural Sciences? No. Cambridge only publishes an overall undergraduate success rate (around 16% for the 2025 cycle, or closer to 11% for international applicants specifically). Natural Sciences is not singled out in Cambridge's published course-by-course commentary, so treat the university-wide figure as the best available proxy.
Does Cambridge accept TOEFL for Natural Sciences applicants? No. Cambridge no longer accepts TOEFL for undergraduate admissions of any kind. IELTS Academic, or an accepted Cambridge English qualification (C1 Advanced/C2 Proficiency), is required instead.
What admissions test do Natural Sciences applicants need to take? The ESAT (Engineering and Science Admissions Test), the same test required for Engineering, Chemical Engineering and Biotechnology, and Veterinary Medicine applicants.
How much does Cambridge's Natural Sciences course cost? As a STEM subject, Natural Sciences sits in Cambridge's higher fee bands: international tuition of roughly $59,247/year plus an average college fee of about $17,798/year, for an estimated total cost of attendance around $93,085/year including living expenses, notably higher than Cambridge's blended average across all subjects.
What IELTS score do I need for Cambridge Natural Sciences? A minimum overall IELTS score of 7.5, with at least 7.0 in each of Listening, Reading, Writing, and Speaking. Cambridge recommends holding at least 6.5 overall with no element below 6.0 at the point of application.
Can I study just one science, like Physics or Biology, from year one at Cambridge? Not directly through Natural Sciences in first year; the course is deliberately structured to keep students studying across multiple sciences before specializing in later years, which is part of what distinguishes it from Oxford's separate single-subject science degrees.
