AQA Paper Structure & Command Words

Understanding the structure of the AQA GCSE Mathematics exam is just as important as knowing the maths itself. This lesson breaks down the three exam papers, explains how the tiers work, introduces every AQA command word, and shows you exactly what the assessment objectives mean for your marks. If you know what the exam is asking, you are far more likely to give the examiner what they want.

The Three Papers

AQA GCSE Mathematics is assessed by three written papers. Together they are worth 240 marks and count for 100% of your grade — there is no coursework.

Paper	Calculator?	Duration	Marks	Weighting
Paper 1	Non-calculator	1 hour 30 minutes	80 marks	33.3%
Paper 2	Calculator allowed	1 hour 30 minutes	80 marks	33.3%
Paper 3	Calculator allowed	1 hour 30 minutes	80 marks	33.3%

Key facts about the papers

• All three papers can cover any topic from the specification — there is no fixed allocation of topics to papers.
• The content is not split between papers. Algebra, geometry, number, ratio, and statistics can all appear on every paper.
• Questions within each paper are arranged roughly in order of difficulty — they start with easier, lower-tariff questions and progress to harder, higher-tariff questions towards the end.
• Each paper has a mix of question types: short single-mark questions, multi-step problems, and extended 5–6 mark questions.

Exam Tip: Do not assume that certain topics only appear on certain papers. AQA can test any topic on any paper. Your revision should cover every specification point, not just the topics you expect to see.

Foundation Tier and Higher Tier

AQA GCSE Mathematics is a tiered qualification. You sit either the Foundation tier or the Higher tier — not both.

Feature	Foundation Tier	Higher Tier
Grade range	Grades 1 – 5	Grades 4 – 9
Maximum grade	Grade 5	Grade 9
Minimum grade	Grade 1 (or U)	Grade 4 (or U)
Content	Approximately 67% of the full specification	100% of the full specification
Difficulty	Questions are more scaffolded and broken into smaller steps	Questions are less scaffolded and require more independent reasoning

Overlap between tiers

There is a significant overlap of content between Foundation and Higher. The majority of specification points are tested at both tiers — only the most advanced topics are Higher-only. This means:

• If you are sitting Foundation, you need to know a substantial amount of mathematics.
• If you are sitting Higher, you will still be tested on Foundation-level content, often in the early questions of each paper.
• The overlap grade band is grades 4 and 5 — these grades can be achieved on either tier.

How the tiers differ in question style

Even when the same topic is tested at both tiers, the question style differs:

Topic	Foundation Question Style	Higher Question Style
Percentages	"Find 15% of £240" (direct calculation)	"After a 15% decrease, the price is £204. Find the original price." (reverse percentage)
Algebra	"Solve 3x + 2 = 14" (two-step equation)	"Solve algebraically the simultaneous equations 3x + 2y = 7 and x² + y = 8"
Geometry	"Find the area of this triangle" (with dimensions given)	"Prove that triangle ABC is similar to triangle DEF and find a missing length"
Statistics	"Find the mean from this data"	"Compare two distributions using appropriate averages and measures of spread"

Exam Tip: If you are aiming for grade 5 on Foundation, you need to answer the harder questions towards the end of the paper correctly. If you are aiming for grade 5 on Higher, you need to secure the easier questions at the start. Choose your tier wisely with your teacher's guidance.

Question Progression Within Each Paper

Each paper starts with the easiest questions and ends with the hardest. Understanding this structure helps you manage your time and expectations.

Typical paper structure (both tiers)

Question Block	Approximate Questions	Marks per Question	Difficulty
Opening questions	Q1–Q5	1–3 marks each	Straightforward recall and application
Middle questions	Q6–Q15	2–4 marks each	Multi-step problems requiring linked skills
Harder questions	Q16–Q22	3–5 marks each	Problem-solving, proof, and reasoning
Final questions	Q23–Q25	4–6 marks each	Extended problems requiring synthesis of multiple topics

The exact number of questions varies from paper to paper, but the progression from easy to hard is consistent.

What this means for your approach

1. Start at Question 1 — do not skip ahead. The early questions are designed to be accessible and will build your confidence.
2. Do not spend too long on any single question — if you are stuck, move on and return later.
3. Expect the last 2–3 questions to be challenging — these are the grade 8/9 questions on Higher and the grade 4/5 questions on Foundation.
4. Every mark matters — a 1-mark question is just as valuable as any other single mark in a 5-mark question.

Exam Tip: A common mistake is to spend 15 minutes on a 4-mark question you find difficult, while skipping three 2-mark questions you could have answered. Always prioritise the marks you can definitely get.

AQA Maths Command Words

Command words tell you exactly what kind of answer the examiner expects. If you respond to a "Show that" question the same way you respond to a "Work out" question, you will lose marks — even if your maths is correct.

Full list of AQA GCSE Mathematics command words

Command Word	What It Means	What to Do
Calculate	Find a numerical answer using mathematical processes	Show your working and give a numerical answer. Calculator may or may not be allowed depending on the paper.
Work out	Find the answer by carrying out a calculation or series of calculations	Very similar to "Calculate". Show clear working and a final answer.
Show that	Prove that a given result is true	You are given the answer — your job is to demonstrate mathematically why it is correct. You must show every step.
Prove	Construct a formal mathematical argument	Use logical steps and mathematical reasoning to establish that a statement is always true. More rigorous than "Show that".
Explain why	Give mathematical reasons for a statement	Use mathematical language and reasoning — a description of what you did is not enough.
Give a reason	Provide a justification for your answer or decision	State a clear mathematical reason, often linked to a property or theorem.
Estimate	Find an approximate answer	Round numbers to convenient values (usually 1 significant figure) and calculate. Show what you rounded to.
State	Write down a result without showing working	A brief, clear answer is sufficient — no working is required.
Write down	Give an answer without showing working	Same as "State" — just give the answer directly.

Understanding "Show that" questions

"Show that" questions are among the most misunderstood question types on the AQA GCSE Mathematics papers. The critical difference is:

• In a "Work out" question, you are finding an unknown answer.
• In a "Show that" question, the answer is already given to you.

Your task in a "Show that" question is to provide a complete chain of mathematical reasoning that leads logically from the information given in the question to the stated result. Even though the answer is printed on the paper, you cannot score full marks by simply writing the answer — you must demonstrate every step.

Why you MUST show every step

    A["Show that question:<br>You are told the answer"] --> B["Start from the given information"]
    B --> C["Show each mathematical step"]
    C --> D["Arrive at the given answer<br>through your working"]
    D --> E["Full marks awarded"]

    A --> F["Common mistake:<br>Jump straight to the answer"]
    F --> G["No method marks<br>0 out of available marks"]

Example of a "Show that" question

Question: Show that (2x + 3)(x - 1) - (x + 2)(x - 3) = x² + 2x + 3

Good answer (full marks):

LHS = (2x + 3)(x - 1) - (x + 2)(x - 3)

Expand first bracket: 2x² - 2x + 3x - 3 = 2x² + x - 3

Expand second bracket: x² - 3x + 2x - 6 = x² - x - 6

Subtract: (2x² + x - 3) - (x² - x - 6) = 2x² + x - 3 - x² + x + 6 = x² + 2x + 3

Therefore LHS = x² + 2x + 3 = RHS as required.

Bad answer (zero marks):

x² + 2x + 3 = x² + 2x + 3 ✓

The second response shows no mathematical reasoning and would score 0, even though the student may understand the mathematics.

Exam Tip: When you see "Show that", plan to write more than you normally would. Make every step visible. The examiner cannot give you method marks for steps that happen in your head.

Assessment Objectives

AQA GCSE Mathematics tests three assessment objectives (AOs). Understanding these helps you recognise what type of thinking a question demands.

Assessment Objective	Description	Percentage of Total Marks
AO1: Use and apply standard techniques	Accurately recall facts, terminology, and definitions. Use and interpret notation correctly. Accurately carry out routine procedures or set tasks.	40%
AO2: Reason, interpret, and communicate mathematically	Make deductions, inferences, and draw conclusions. Construct chains of reasoning. Interpret and communicate information accurately. Present arguments and proofs. Assess the validity of an argument.	30%
AO3: Solve problems within mathematics and in other contexts	Translate problems in mathematical or non-mathematical contexts into mathematical processes. Make and use connections between different parts of mathematics. Interpret results in the context of the given problem. Evaluate methods used and results obtained. Evaluate solutions to identify how they may have been affected by assumptions made.	30%

What this means in practice

• 40% of the exam is AO1 — this is your bread and butter. These are the questions where you use a standard method to find an answer. Practising procedures until they are automatic is the best way to secure these marks.
• 30% is AO2 — this includes "Explain", "Give a reason", and "Prove" questions. You need to communicate your mathematical thinking clearly using correct terminology.
• 30% is AO3 — these are problem-solving questions, often set in a real-world context. You need to identify which mathematical techniques to apply and then interpret your answer.

How AOs appear in questions

A single question may test more than one AO. For example, a 5-mark problem-solving question might award:

• 1 mark for AO1 (correct calculation)
• 2 marks for AO2 (logical chain of reasoning)
• 2 marks for AO3 (selecting the right approach and interpreting the result)

Exam Tip: AO2 and AO3 together account for 60% of the exam. Simply knowing how to carry out calculations (AO1) is not enough for a high grade. You must also practise reasoning and problem-solving questions.

Quality of Written Communication (QWC) Marks

Some questions on the AQA GCSE Mathematics papers carry marks for "Quality of Written Communication" or "Quality of Extended Response" (QER). These are typically 4–6 mark questions that require an extended piece of mathematical reasoning.

What the examiner looks for

QWC Criterion	What It Means
Logical structure	Your working follows a clear, step-by-step order
Mathematical language	You use correct terminology (e.g., "gradient", "perpendicular", "coefficient")
Complete reasoning	Every step is shown — no gaps in the logic
Clear presentation	Working is legible and well-organised
Correct notation	You use equals signs, inequality symbols, and algebraic notation correctly

Tips for QWC questions

1. Write in a logical order — set out your working from top to bottom with each step following naturally from the previous one.
2. Use mathematical vocabulary — instead of "the number in front of x", write "the coefficient of x".
3. Do not skip steps — even if a step seems obvious to you, write it down.
4. Use equals signs correctly — do not write a chain like 3x + 2 = 14 = 3x = 12 = x = 4. Each line should be a correct statement.
5. State your conclusion clearly — if the question asks "Is Ahmed correct?", finish with a clear "Yes" or "No" with your mathematical justification.

flowchart LR
    A["Read the question<br>Identify what to show"] --> B["Plan your approach"]
    B --> C["Write each step<br>with correct notation"]
    C --> D["Use mathematical<br>vocabulary"]
    D --> E["State your conclusion<br>clearly"]

Exam Tip: QWC marks are often the difference between grade boundaries. A student who solves the problem but presents their working in a jumbled order may lose 1–2 marks compared to a student who presents the same solution clearly. Practise laying out your working neatly.

Practical Advice: How to Read an AQA Maths Exam Paper

When you first open your exam paper, take 30 seconds to do the following:

1. Check the front cover — confirm you have the correct paper (Paper 1, 2, or 3) and the correct tier (Foundation or Higher).
2. Flick through the paper — count the number of questions and get a rough sense of the topics. This takes 20 seconds and reduces anxiety.
3. Note the total marks — it should be 80. If it is not, raise your hand immediately.
4. Read each question carefully — underline the command word and the key information.
5. Check for diagrams — many geometry and statistics questions include diagrams with important information. Read the labels.
6. Note "NOT drawn accurately" — if this appears, do not measure angles or lengths from the diagram. Use the given values and mathematical methods.

Reading mark allocations

Marks	What It Tells You
1 mark	A single step — usually "State" or "Write down"
2 marks	Two steps or a short calculation with a final answer
3 marks	A multi-step calculation; method marks + answer mark
4 marks	An extended calculation or reasoning; expect 3–4 lines of working
5–6 marks	A problem-solving question or "Show that" / "Prove" question; plan before you write

Exam Tip: The number of marks is your biggest clue to how much work is expected. If a question is worth 1 mark, a single line is enough. If it is worth 5 marks, you need a full chain of working. Match your effort to the marks available.
