Biology is a fascinating natural science that aims to understand how animals and organisms work – by studying the largest mammal to the smallest microbe. It is an excellent subject to study in its own right and can lead to research into animals, plants and microscopic organisms, as well as their environment and how they develop and live. It is also very useful for careers in medicine, the life sciences, environmental science, sports, engineering and the food industry, as well careers in policing and emergency services.
The subject entails a detailed study of the mechanics of plant and animal life, both in theoretical and practical terms. It studies the physical and chemical structure, function, development and evolution of living organisms.
Topics covered include biochemistry, cell biology, physiology, genetics and ecology. There is also a strong practical element to the course, which aids understanding of the theoretical material and contributes to the final grade. The practical skills assessed are those of planning, carrying out experiments and drawing conclusions. Human Biology covers much of the same material, but with a closer focus on issues such as the causes and control of various diseases in homo sapiens, and the interaction of physiological systems across the lifespan of an individual.
AQA A-Level Biology is taught within the two-year A-Level programme.

5 GCSEs grade 5 or above including Maths and English or equivalent international qualifications.
For international students who have taken IELTS, we require an overall score of 5.5 with a minimum of 5.5 for each of the reading and writing components.
For international students who have taken IGCSE English (Second Language), we require grade 5 or above.
A minimum of grade 5 in one of GCSE Biology, GCSE Science or IGCSE Double Science or international equivalent.
Biology combines well with other science subjects (physics, chemistry and psychology) and mathematics.
