AQA GCSE Exam Command Words Explained: What Every Student Needs to Know

Every AQA exam question contains a command word. It is the word that tells you exactly what the examiner wants you to do. And yet, misreading or ignoring the command word is one of the most common reasons students lose marks.

The problem is not that students do not know the content. It is that they answer a different question to the one being asked. A student who writes a detailed explanation when the question only asks them to "state" something is wasting time. A student who simply describes when the question asks them to "evaluate" will not earn the higher-level marks, no matter how accurate their description is.

AQA publishes an official list of command words that apply across all their GCSE specifications. Understanding exactly what each one requires is a genuine exam technique skill, and it is one that can be learned and practised. This guide covers every AQA GCSE command word, with real examples and the mistakes you need to avoid.

Why Command Words Matter So Much

Mark schemes are written around command words. When an examiner marks your paper, they are checking whether your response does what the command word asks. If the question says "Explain" and you only describe, you will hit a ceiling on the marks available to you, even if everything you write is factually correct.

Think of the command word as an instruction from the examiner. It tells you three things:

1. What type of response is needed -- a single word, a sentence, a structured paragraph, or a full essay.
2. The depth of thinking required -- recall, application, analysis, or evaluation.
3. How to structure your answer -- whether you need to give reasons, make comparisons, or weigh up evidence.

Getting this right means you work efficiently, answer the actual question, and give the examiner exactly what the mark scheme is looking for.

Lower-Demand Command Words

These command words require you to recall or identify information. They typically appear on questions worth 1-2 marks.

State / Give / Name

What it means: Provide a short, factual answer. No explanation or justification is needed.

What the examiner wants: A word, phrase, or short sentence. Nothing more.

Example (Science): "State the name of the process by which plants make glucose." Good answer: Photosynthesis. Common mistake: Writing a paragraph explaining how photosynthesis works. This wastes time and earns no extra marks.

Example (History): "Give one reason why the Weimar Republic faced opposition." Good answer: The Treaty of Versailles caused resentment among many Germans.

Identify

What it means: Recognise and name something, often from a source, diagram, graph, or data table.

What the examiner wants: A specific piece of information picked out from the stimulus material.

Example (Geography): "Identify the month with the highest rainfall from the climate graph." Good answer: July. Common mistake: Describing the overall pattern of rainfall instead of identifying the specific month.

Label

What it means: Add names or annotations to a diagram, chart, or graph.

What the examiner wants: Accurate labels in the correct positions, usually with lines or arrows pointing to the right feature.

Example (Biology): "Label the mitochondria on the diagram of the animal cell." Common mistake: Drawing the label line to the wrong organelle, or writing a description instead of a label.

List

What it means: Provide a number of points, items, or features. No explanation needed.

What the examiner wants: Separate, distinct points. Usually, the number of points matches the number of marks.

Example (Chemistry): "List three properties of metals." Good answer: Good conductors of electricity, malleable, high melting points.

Mid-Demand Command Words

These require more than simple recall. You need to demonstrate understanding by describing processes, explaining causes, or applying knowledge.

Describe

What it means: Give an account of something. Say what happens, what something is like, or what you observe. You do not need to explain why.

What the examiner wants: A clear, factual account that covers the key points. Include data or specific details where relevant.

Example (Physics): "Describe the pattern shown in the graph." Good answer: As the force increases, the extension of the spring increases proportionally up to 6N. Beyond 6N, the extension increases more rapidly for each unit of force added. Common mistake: Explaining why the pattern occurs (mentioning Hooke's law or the limit of proportionality) when the question only asks you to describe what the graph shows.

Example (Geography): "Describe the distribution of tropical rainforests." Good answer: Tropical rainforests are found between the Tropics of Cancer and Capricorn, close to the equator. Large areas are found in South America (the Amazon), Central Africa (the Congo Basin), and Southeast Asia.

Explain

What it means: Give reasons for something. Say why something happens, not just what happens.

What the examiner wants: A clear statement linked to a reason, often using connective words like "because", "this means that", "therefore", or "as a result".

Example (Biology): "Explain why the rate of photosynthesis increases as light intensity increases." Good answer: As light intensity increases, more light energy is available for the light-dependent reactions of photosynthesis. This means more chlorophyll molecules can absorb light, so the rate at which carbon dioxide and water are converted into glucose and oxygen increases. Common mistake: Simply stating that more light means more photosynthesis without explaining the mechanism.

Example (History): "Explain why the Berlin Wall was built in 1961." Good answer: The Berlin Wall was built because large numbers of East Germans were migrating to West Berlin, attracted by better living standards and political freedom. This was embarrassing for the Soviet Union and was draining East Germany of its skilled workforce, so Khrushchev ordered the border to be closed.

Suggest

What it means: Apply your knowledge to an unfamiliar situation. There may not be a single correct answer -- the examiner is looking for a plausible, well-reasoned response.

What the examiner wants: A sensible answer that shows you can think beyond what you have memorised. Use your understanding of principles to reason through the scenario.

Example (Chemistry): "The student noticed that the rate of reaction was slower on a cold day. Suggest why." Good answer: At lower temperatures, the particles have less kinetic energy, so they move more slowly. This means there are fewer successful collisions per second, so the rate of reaction decreases.

Calculate

What it means: Work out a numerical answer. You must show your working.

What the examiner wants: A clear mathematical process leading to a correct answer with appropriate units. Even if your final answer is wrong, you can earn marks for correct working.

Example (Physics): "Calculate the resistance of the wire. Use the equation R = V/I." Common mistake: Not showing working. If your final answer is wrong but your method is correct, you lose all the marks if you have not shown your steps.

Determine

What it means: Use given data or information to work something out. Similar to calculate but may involve interpreting data rather than just plugging numbers into a formula.

What the examiner wants: A methodical approach to extracting and using information to reach a conclusion.

Sketch

What it means: Draw approximately. For graphs, this means getting the shape and key features right, but exact plotting is not required. For diagrams, the key features should be recognisable.

What the examiner wants: The correct general shape or structure. Label axes, mark key points, and show the right trend.

Higher-Demand Command Words

These appear on questions worth more marks (typically 4-6 marks) and require analysis, evaluation, or extended reasoning.

Compare

What it means: Identify similarities and/or differences between two or more things.

What the examiner wants: Direct, explicit comparisons. Use phrases like "whereas", "in contrast", "both", "similarly", and "on the other hand". Do not just describe each thing separately.

Example (Geography): "Compare the economic development of the UK and Nigeria." Bad answer: "The UK has a high GDP. Nigeria has a low GDP." (These are two separate statements.) Good answer: "The UK has a significantly higher GDP per capita than Nigeria, whereas Nigeria has a faster rate of economic growth."

Common mistake: Writing about each item in turn without making direct links between them. Every comparison point should reference both items.

Evaluate

What it means: Weigh up evidence, arguments, or options and reach a supported conclusion. Consider both sides before making a judgement.

What the examiner wants: A balanced discussion that considers strengths and weaknesses, advantages and disadvantages, or evidence for and against. Then a clear concluding statement that states your overall judgement with justification.

Example (Science): "Evaluate the use of embryonic stem cells in medical treatment." Good answer structure:

• Arguments for: can differentiate into any cell type, potential to treat conditions like paralysis and diabetes.
• Arguments against: ethical concerns about destroying embryos, risk of tumour formation, rejection by the immune system.
• Conclusion: On balance, the potential to treat otherwise incurable conditions justifies continued research, provided ethical guidelines are followed.

Common mistake: Only giving one side of the argument. Even if you have a strong opinion, you must address counterarguments to access the top marks.

Justify

What it means: Give reasons for your answer or decision. You need to explain why your choice is the best option or why your conclusion is valid.

What the examiner wants: A clear link between your conclusion and the evidence or reasoning that supports it. "I chose X because..." followed by specific reasons.

Discuss

What it means: Present different aspects, perspectives, or arguments related to a topic. Similar to evaluate but does not always require a final judgement.

What the examiner wants: A well-structured response that explores multiple viewpoints or factors, with supporting evidence or examples for each.

Assess

What it means: Consider the importance, value, or significance of something. Similar to evaluate but often focuses on the extent or degree of something.

What the examiner wants: A measured response that considers different factors and reaches a judgement about their relative importance.

"How far do you agree?" / "To what extent?"

What it means: These are not single command words but command phrases common in History, English, and Geography. They ask you to consider a statement and decide how much you agree with it.

What the examiner wants: A balanced argument that considers evidence both supporting and challenging the statement, followed by a clear judgement. The best answers sustain their argument throughout rather than simply listing points for and against.

Applying Command Words Across Subjects

One of the important things to understand about AQA command words is that they mean the same thing regardless of the subject. "Explain" requires reasons in Biology just as it does in Geography or Religious Studies. However, the style of response may differ:

• In sciences, explanations tend to follow a cause-and-effect chain using scientific terminology.
• In humanities, explanations often involve linking factors to outcomes with supporting evidence or examples.
• In English Literature, explanations require close reference to the text, often with embedded quotations.

Understanding this consistency means you can transfer your command word skills across all your GCSEs, not just the subject you happen to be revising at the time.

A Practical Strategy for Command Words

Here is a simple approach you can use in every exam:

1. Read the question and circle the command word. This takes two seconds and forces you to notice it.
2. Check the marks available. A 1-mark "State" question needs a single point. A 6-mark "Evaluate" question needs a structured, balanced response.
3. Plan before you write. For questions worth 4+ marks, spend a minute jotting down your key points before writing your answer. This prevents you from going off-track.
4. Re-read your answer. Before moving on, check that your response actually does what the command word asks.

Practise with Purpose

The best way to get better at interpreting command words is to practise with real exam questions. When you review your answers, do not just check whether the content is correct -- check whether you answered the right type of question.

LearningBro's GCSE exam preparation courses for subjects including Biology, Chemistry, Physics, and History are designed to test your ability to respond to different command words correctly. Each lesson includes questions that mirror the style and demand of real AQA exam papers, so you build the right habits before exam day.
