Studying Biological and Biomedical Sciences in the UK and Ireland

A subject-deep guide to biology, biomedical science, biochemistry, genetics and microbiology degrees in the UK and Ireland — structures, entry subjects and how they differ from medicine.

Last updated 24 June 2026

Key facts

Typical BSc length: 3 years (4 in Scotland; integrated MSci/MBiol is 4)
Apply via: UCAS (UK) / CAO (Ireland)
Common entry subjects: Biology + often Chemistry (verify per course)
Accreditation body: Royal Society of Biology (where offered)

What the life-science family of degrees covers

"Biological sciences" and "biomedical sciences" are umbrella terms for a large family of related degrees. Common named routes include Biology, Biomedical Science, Biochemistry, Genetics, Microbiology, Molecular Biology, Pharmacology, Physiology, Neuroscience and Zoology. Many UK and Irish universities also offer a broad "Biological Sciences" degree where you specialise after a shared first year.

Broadly, biology degrees lean toward whole organisms, ecology and evolution, while biomedical science focuses on human health, disease mechanisms and the laboratory science behind diagnosis and treatment. Biochemistry and molecular biology sit at the chemistry–biology interface. Because the boundaries overlap, always read the individual course page for the exact module list rather than relying on the degree title alone.

Biology / Biological Sciences — broad, often with later specialisation
Biomedical Science — human health, disease and diagnostics
Biochemistry / Molecular Biology — molecules, genes and cellular processes
Genetics, Microbiology, Pharmacology, Physiology, Neuroscience, Zoology — focused routes

Typical course structure

Most UK bioscience degrees run three years for a BSc (Honours), or four years as an integrated master's (BSc plus an MSci/MBiol final year — see the separate integrated-master's guide). Scottish degrees are commonly four years with a broader first two years. In Ireland, many science degrees run four years and admit you into a general "Science" denominated entry before you choose a specialism.

A typical year one builds core foundations — cell biology, genetics, biochemistry and lab skills — shared across several bioscience pathways. Later years narrow toward your chosen subject, with more research-style practicals, data analysis and often a final-year dissertation or laboratory project. Some courses offer a year in industry or a research placement; the dedicated placement guide in this set explains how those work.

Year 1: shared foundations and laboratory skills
Years 2–3: increasing specialisation and research methods
Final year: dissertation or extended lab/research project
Optional: placement year or study-abroad year

Entry subjects and what universities look for

Bioscience courses almost always expect Biology and usually a second science — most often Chemistry — at A-level, Higher, IB Higher Level or an equivalent. Biochemistry and pharmacology routes tend to weight Chemistry heavily. Mathematics is increasingly valued because modern biology is data-rich. Each university sets its own subject and grade requirements, so check the specific course page.

International qualifications are widely accepted. Universities map A-levels, the IB, and many national qualifications to their own entry standards, and most publish country-specific guidance plus an English-language requirement. Do not assume a fixed grade — entry standards differ by university and course and change each cycle, so verify the current requirements on the official course page.

Usually required: Biology
Often required/preferred: Chemistry; sometimes Maths or another science
Check: GCSE/Leaving Certificate subject minimums and English-language evidence
Always confirm current grades on the official university course page

How bioscience differs from medicine

A biomedical science degree is not the same as studying Medicine. Medicine (and Dentistry) are clinical professional degrees that lead toward licence to practise and are regulated by bodies such as the GMC and GDC; they have separate, more competitive admissions, often including an admissions test like the UCAT and an interview. A biomedical or biological science degree is an academic science degree — it teaches the underlying science but is not, by itself, a route to becoming a doctor.

That said, bioscience graduates work across research, laboratories, biotech and pharmaceutical industries, healthcare science, teaching and further study. Some use a strong bioscience degree as a stepping stone to graduate-entry Medicine, but that is a separate, competitive application with its own requirements. If your goal is clinical practice, research the medicine route directly rather than assuming a bioscience degree converts automatically.

Medicine/Dentistry: clinical, regulated, separate competitive admissions
Biomedical/biological science: academic science degree, not a licence to practise
Graduate-entry Medicine after bioscience is possible but a separate application

How to apply and where to research

Undergraduate applications to UK universities go through UCAS; applications to Irish universities go through the CAO. Both use a single application with course choices and (for UCAS) a personal statement. International students apply through the same systems, with extra steps for English-language evidence and, after an offer, the student visa.

Use official course pages to confirm module content, entry subjects, accreditation and any placement options. The Royal Society of Biology accredits many bioscience degrees, which can signal a recognised standard and a clear route toward professional registration — check whether a course you like is accredited.

UK: apply via UCAS
Ireland: apply via the CAO
Confirm modules, entry subjects and accreditation on the official course page
Look for Royal Society of Biology accreditation as a quality signal

Frequently asked questions

Is biomedical science the same as medicine?

No. Medicine is a regulated clinical degree leading toward licence to practise, with separate, competitive admissions (often a UCAT/admissions test and interview). Biomedical science is an academic science degree about the science behind health and disease; it does not by itself qualify you as a doctor.

Do I need Chemistry as well as Biology?

Many bioscience courses prefer or require Chemistry alongside Biology, especially biochemistry and pharmacology routes. Requirements vary by university and course, so check the specific official course page for the subjects and grades it asks for.

Can a biology degree lead to graduate-entry medicine?

It can be a stepping stone, but graduate-entry Medicine is a separate, competitive application with its own entry requirements and tests. A bioscience degree does not convert automatically — research the medicine route directly if clinical practice is your goal.

What can I do with a bioscience degree?

Graduates work in research, laboratories, biotechnology and pharmaceuticals, healthcare science, data and analytics, teaching and further postgraduate study. The exact options depend on your specialism, placements and skills — check graduate-destination information on each course page.
