Entry requirements for a biology degree

Universities require candidates to have biology at A level or an equivalent for a degree in biology. Most universities also require maths and chemistry at A level or equivalent. The requirements for biology-related courses may differ, but with maths, biology and chemistry at A level, you'd meet most universities' requirements.

Types of degrees in biology

You can follow a general degree or choose one of these more specialised degrees:

Human biology

A degree in human biology focuses on human health and development. The topics for this degree are human genetics, microbiology and disease. The degree considers related interdisciplinary social science topics exploring the impact of technology and society on human development.

Marine biology

A degree in marine biology explores the diverse marine life from the deep sea to coastal margins. Students learn about marine organisms' biology, ranging from microbes to marine vertebrates and marine algae. During this degree, students learn practical scientific skills to become practising marine biologists.

Molecular biology

A degree in molecular biology focuses on the function and structure of biologically important molecules. Topics covered during the degree include DNA, RNA, proteins and molecular events governing cell functions. The degree also explores some aspects of genetics, cell biology and biochemistry. During this degree, students learn theories and practical lab skills.

Cell biology

A degree in cell biology integrates principles from various disciplines, including physics, chemistry, genetics, physiology and biochemistry. Students learn about organic and physical chemistry. Other topics covered in this degree include cell, developmental and molecular biology.

A degree in microbiology focuses on studying microorganisms and emphasises the biology of bacteria, fungi, viruses and other microorganisms. Students learn about the pathogenic potential of the organisms that cause disease in humans. The degree also covers aspects of the biochemistry, genetics and physiology of microorganisms.

Courses students take during degrees in biology

During the first year of study, you take modules to prepare you for the rest of your degree. A general degree in biology includes a broad range of modules focusing on biomolecules, ecosystems and the genetic and biochemical processes of plants, microbes and animals. When you pursue a more specialised degree, your courses include general biology modules specialised ones. For example, if you study for a degree in marine biology, you may have modules focusing on marine biology and general biology. Typical first-year modules may include cell biology, physiology, microbiology and basic biochemistry.

You may start with a general degree but can specialise as your studies continue. You can take modules such as biotechnology, selective toxicity, immunology and molecular neuroscience to specialise. The options for specialisation differ between universities.

How long does a degree in biology take?

A bachelor's degree in biology takes approximately three years, and some universities allow students to graduate with a master's degree with one additional year of study. A doctorate in a specialised area of biology may be a requirement to become a research scientist or a university lecturer. A doctorate typically takes between three and six years, depending on whether a student does it full-time or part-time.

What to expect when studying biology at university

Universities use the following teaching methods for degrees in biology:

  • Lectures: The primary teaching method for this degree is lectures. Students listen to lectures and take notes of important points mentioned by the lecturer.

  • Laboratory sessions: A degree in biology includes practical work in a laboratory where you can do various experiments and tests to support the theoretical content of your degree.

  • Fieldwork: Fieldwork is work you do outside the university in a natural environment.

  • Seminars: Seminars take place when a small group of students get together to discuss a specific topic with the help of a tutor.

  • Computer sessions: Students learn to use computers to analyse numbers for statistical purposes.

  • Self-study: Students spend a substantial amount of time going through the coursework, preparing for lectures and studying by themselves.

Skills learned during a degree in biology

A degree in biology teaches students several valuable skills that students can use in their careers: These skills include:

  • Data management: These skills include the ability to use and manage information effectively. It also involves the ability to look for patterns in data.

  • Computer literacy: Biology students learn to use computers and popular software packages, including word processing and spreadsheets.

  • Research skills: These skills are the ability to find information about a specific topic and evaluate it. It includes conducting investigations, using critical analysis and developing hypotheses about particular issues.
