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.
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% |
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.
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 |
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:
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.
Each paper starts with the easiest questions and ends with the hardest. Understanding this structure helps you manage your time and expectations.
| 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.
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.
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.
| 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. |
"Show that" questions are among the most misunderstood question types on the AQA GCSE Mathematics papers. The critical difference is:
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.

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

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.
When you first open your exam paper, take 30 seconds to do the following:
| 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.
Exam Tip: Before you start revising maths content, make sure you understand the exam structure. Knowing how the exam works allows you to allocate your time effectively, tailor your answers to what the examiner is looking for, and avoid losing marks through misunderstanding the question type.
Understanding the AQA exam at a structural level is only part of the battle. The other part is developing a repeatable strategic routine that you follow on every paper. Examiners report that the single largest predictor of a strong performance is not raw mathematical talent but disciplined exam craft — pacing, careful reading, accurate notation and a willingness to attempt every part of every question.
Many students dive straight into Question 1 the instant the invigilator says "begin". A more effective approach is to spend the first 60–90 seconds scanning the entire booklet. Note the marks per page, identify at least two questions you can see an immediate approach for, and flag any diagrams that will require careful reading. Only then start at Question 1. This tiny investment calms nerves and primes your brain to recognise familiar patterns later in the paper.
Examiners consistently report that candidates confuse Show that, Prove, Explain why and Give a reason. The table below contrasts them directly:
| Command | Formal rigour required | Typical mark allocation | Is the answer given? | What the examiner rewards |
|---|---|---|---|---|
| Calculate / Work out | Low to medium | 1–5 | No | Correct numerical answer with working |
| Show that | Medium | 2–5 | Yes | Every intermediate step from the given data to the printed result |
| Prove | High | 3–6 | Sometimes | A generalised algebraic argument using letters, not examples |
| Explain why | Medium | 1–3 | No | A sentence linking a mathematical property to the specific case |
| Give a reason | Low | 1 | No | A named theorem, fact, or definition |
| Estimate | Low | 2–3 | No | Rounded values shown plus the computation |
| Comment on | Medium | 1–2 | No | A short statistical/contextual interpretation |
Question (5 marks, Paper 1, Higher): The numbers a, b and c are three consecutive integers with a<b<c. Show that b2−ac=1.
Model solution. Let a=n−1, b=n and c=n+1 for some integer n. Then
b2−ac=n2−(n−1)(n+1)=n2−(n2−1)=1.
Because the expression evaluates to 1 independently of the integer n chosen, the identity b2−ac=1 holds for every triple of consecutive integers, as required.
Why this scores 5/5. The candidate introduces algebraic letters (method mark), uses the difference of two squares (n−1)(n+1)=n2−1 (accuracy mark), simplifies cleanly (accuracy mark), and explicitly states that the argument is general (QWC mark). A solution that tested only a=3,b=4,c=5 would at most earn 1 mark because it does not prove the statement — it only verifies a single case.
A useful shorthand for all three AQA papers is:
Exam Tip: On Paper 1 in particular, write the numbers 5,15,30,45,60,75,90 faintly at the top of the cover sheet as a pacing ladder. Glance at your watch at each checkpoint.
Exam-style question (3 marks): AQA command words. State the command word and explain what it requires you to do in full: "Work out the value of x when 3x−5=16."
Grade 3–4 response. The command word is "Work out". This means I need to carry out a calculation and give a numerical answer. I solve: 3x−5=16, so 3x=21, giving x=7.
Grade 5–6 response. The command word "Work out" requires a calculated numerical result supported by clear working so that method marks can be awarded. Starting from 3x−5=16, I add 5 to both sides to obtain 3x=21, then divide both sides by 3 to give x=7. I present each step on a new line with correctly used equals signs.
Grade 7–9 response. "Work out" is an AO1 command word asking for the accurate application of a standard technique, here the solution of a linear equation in one unknown. Because method (M) marks are dependent on visible working, I present an equivalent sequence of linear equations: 3x−5=16⇒3x=21⇒x=7. The single value x=7 satisfies the original equation since 3(7)−5=21−5=16, which I verify to confirm accuracy. Contrast this with "Show that x=7", where x=7 would already be stated and the expectation would be a full substitution-based verification rather than a solution.
