Biology is the study of life, from the molecular building blocks of cells up to the interconnectedness of ecosystems. By making sense of the living world around us we learn how different organisms function and interact with their environment. This knowledge gives us insights into the complexities of cellular metabolism, genetic inheritance, evolution, the importance of biodiversity, and the delicate balance that sustains life on Earth. Studying biology has a direct impact on society as it advances medicine, agriculture, and environmental protection, helping us fight diseases, grow food sustainably, and address challenges such as climate change.
Course type: A level
Board: OCR
Head of department: Mr R Buttinger
Entry requirement: Grade 7 (double) or grade 6 (triple) in GCSE biology; grade 6 GCSE maths; five grade 5s at GCSE including English
How will A level biology be delivered and assessed?
| Component | Content | Assessment |
| Year 12 | Introduction to foundational concepts in biology. Gas exchange and transport systems. Biodiversity, evolution and disease. Practical work supports theoretical content. | End of year exams. |
| Year 13 | Builds on year 12, introducing more complex topics including neural and hormonal communication, metabolism and genetics. Practical work supports theoretical content. | Three written exams at the end of year 13; practical skills assessed via written papers and endorsement. |
| Practical endorsement | Ongoing assessment of 12 required practical activities throughout the two-year course. | Reported separately alongside A level grade. Not included in grade weighting. |
Topics covered
Year 12
