AQA A-Level Environmental Science (7447): complete guide to the modules and the exams

A complete guide to AQA A-Level Environmental Science (specification 7447). Covers the major content areas from the living and physical environment through energy, pollution, biological resources and sustainability, how the two written papers are structured and marked, the practical and fieldwork skills, the maths demand, and how to study each area for top grades.

AQA A-Level Environmental Science (specification 7447) is a two-year linear course assessed by two written papers at the end of Year 13. It is an interdisciplinary subject combining biology, chemistry, geography and physics, with a strong emphasis on fieldwork, data handling and the evaluation of environmental issues. This page is the index: below is a map of the content areas, the exam structure, and how to study each one.

The AQA Environmental Science content areas

The specification is organised into major content areas that build a complete picture of environmental systems and human impacts.

The living environment
The conditions that allowed life on Earth, biodiversity at genetic, species and habitat levels, the carbon and nitrogen cycles, conservation of biodiversity, and energy flow and productivity in the biosphere.
The physical environment
The composition and structure of the atmosphere and the greenhouse effect, the hydrosphere and water cycle, mineral resources and mining, the phosphorus and sulfur biogeochemical cycles, and soils.
Energy resources
Fossil fuels, nuclear power, the main renewable energy resources, and energy conservation and efficiency, with the trade-offs between them.
Pollution
The nature of pollution and the properties of pollutants, air pollution, water pollution and eutrophication, solid waste and land pollution, and pollution control.
Biological resources
Agriculture and food production, aquatic food production and overfishing, and forest resources and deforestation, with sustainable management throughout.
Sustainability and research methods
The principles of sustainability, monitoring and sampling techniques, and dealing with environmental data, including statistics.

Exam structure

AQA A-Level Environmental Science is assessed by two written papers, both sat at the end of the course. A calculator is allowed in both papers.

  • Paper 1 - around 3 hours, about 120 marks, 50%. Knowledge, application and evaluation drawn from across the specification, including data-response and extended-response questions.
  • Paper 2 - around 3 hours, about 120 marks, 50%. The same style, also drawing on content from across the course, with strong emphasis on the analysis of environmental issues and data.

At least 10% of marks assess maths skills, and the practical, fieldwork and data-handling skills are assessed within the written papers.

How to study AQA Environmental Science

Environmental Science rewards precise definitions, clear understanding of processes, and balanced evaluation.

  1. Work from the specification statements. Each content point is a checklist; questions are written from them.
  2. Learn processes precisely. Eutrophication, biomagnification, the nitrogen and carbon cycles, and the greenhouse effect must be written accurately.
  3. Drill data handling and statistics. Means, standard deviation, statistical tests, and correlation versus causation recur throughout the papers.
  4. Master fieldwork methods. Quadrats, transects, mark-release-recapture and random replicated sampling appear in applied questions.
  5. Practise evaluation. Many marks reward weighing the advantages and disadvantages of energy resources, farming systems and management strategies.

The content areas, topic by topic

Each area has specification-level answer pages with worked exam questions and cross-links, plus an overview guide and quiz per module. Browse the full set at /a-level-aqa/environmental-science/syllabus.

For the official specification

AQA publishes the full specification (7447), past papers and mark schemes at aqa.org.uk. Always revise from the current specification and AQA's own past papers, because question style and the emphasis on evaluation and data response are board-specific.

Common questions about Environmental Science

How is AQA A-Level Environmental Science (7447) structured?
AQA A-Level Environmental Science is a two-year linear course assessed by two written exams at the end of Year 13. The subject content runs from the living environment and the physical environment, through energy resources, pollution, biological resources, and sustainability and research methods. It is an interdisciplinary subject drawing on biology, chemistry, geography and physics, with a strong emphasis on fieldwork, data handling and the evaluation of environmental issues. There is no coursework grade, but practical and fieldwork skills are assessed within the written papers.
What are the AQA A-Level Environmental Science exam papers?
AQA A-Level Environmental Science is assessed by two written papers sat at the end of the course, each worth 50 percent of the A-level. Each paper is around 3 hours and 120 marks. The papers test knowledge and understanding from across the whole specification, including data-response questions, applied problem solving, and extended responses that require the evaluation of environmental issues. Practical and fieldwork skills, and the handling of environmental data, are assessed within these written papers rather than in a separate exam.
How much maths is in AQA A-Level Environmental Science?
At least 10 percent of the marks assess mathematical skills at Level 2 (roughly GCSE higher tier and above). Expect calculating means, ranges and percentages, working with standard form, plotting and interpreting graphs, calculating standard deviation, choosing and applying statistical tests, and judging the significance of results. A calculator is allowed in both papers. The data-handling skills from the research-methods content are examined throughout.
What practical and fieldwork skills does the course require?
Environmental Science is fieldwork-heavy. Students learn to sample populations and habitats using quadrats, transects and capture techniques such as mark-release-recapture, to measure abiotic factors such as temperature, light, pH and dissolved oxygen, to use indicator species and biological oxygen demand to monitor pollution, and to plan investigations with random replicated sampling. These skills, and the analysis of the resulting data, are assessed within the written papers.
How should I structure my AQA A-Level Environmental Science revision?
Work area by area against the specification statements, because questions are written directly from them. Learn definitions and processes precisely (for example eutrophication, biomagnification and the nitrogen cycle), drill the data-handling and statistics skills until they are automatic, and practise structured evaluation answers, since many marks reward weighing the advantages and disadvantages of resources and management strategies. Apply sampling and statistics to data from across the course.
How does AQA A-Level Environmental Science compare to other subjects and boards?
Environmental Science overlaps with biology, geography and chemistry but is distinct in its focus on environmental systems, resource management, pollution and sustainability, with a strong fieldwork and data-handling strand. AQA's specification (7447) is one of the main A-level routes into the subject. Always revise from the current AQA specification and AQA past papers, because question style and the emphasis on evaluation and data response are board-specific.
