What Will Students Learn?
AS Level (Year 12) - Foundations of Biological Science
In the first year, students build a broad foundation covering the molecular and cellular basis of life. They study biological molecules such as carbohydrates, lipids, proteins and nucleic acids, and learn about enzyme action, membranes, transport mechanisms, gas exchange, cell structure, division and the basics of genetics and inheritance. Students also examine the cardiovascular system and human health, delving into topics such as blood composition, circulation, gas exchange, and risk factors related to disease. Alongside theory, students engage in practical skills development - microscopy, cell analysis, and basic experimental work - to understand living systems at a micro and macro level.
A-Level (Year 13) - Advanced Concepts and Applied Biology
In the second year, learning advances through units that examine organisms in ecological, physiological and evolutionary contexts. Students explore topics such as energy flow, photosynthesis and respiration, ecosystems, biodiversity, natural selection and conservation. They study human physiology in greater depth, covering coordination, homeostasis, hormonal control, the nervous system, immunity, microbiology and gene technologies. Experimental biology remains a core focus: students learn to design, conduct and evaluate investigations, interpret data, and draw evidence-based conclusions.
Skills & Understanding Developed
Throughout the course, students develop a wide range of scientific skills:
- Design experiments, collect and analyse data, evaluate methodological reliability, and write coherent scientific reports.
- Critical thinking and quantitative reasoning - calculations, statistical analysis, graphs and sampling methods.
- Apply theory to novel or unfamiliar contexts.
- Practical lab skills: safe handling of equipment, accurate measurement, microscopy, and biological techniques.
- Scientific literacy, ethical awareness (e.g., in genetics, conservation, environmental change).
- Independent problem-solving and research abilities.
Examination Structure
The full IAL Biology qualification is assessed across six externally examined units.
| Unit | Title / Content Focus | Duration |
|---|---|---|
| Unit 1 | Molecules, Transport and Health | 1 hr 30 min |
| Unit 2 | Cells, Development, Biodiversity and Conservation | 1 hr 30 min |
| Unit 3 | Practical Biology and Research Skills I (linked to Units 1 and 2) | 1 hr 20 min |
| Unit 4 | Energy, Environment, Microbiology and Immunity | 1 hr 45 min |
| Unit 5 | Respiration, Internal Environment, Coordination and Gene Technology | 1 hr 45 min |
| Unit 6 | Practical Biology and Research Skills II (linked to Units 4 and 5) | 1 hr 20 min |
Completing all six units leads to the full International A-Level (IAL) award. Students may also exit after Units 1-3 with the International AS (IAS) qualification.
