What Is GCSE Maths Paper 1?
How Long Is GCSE Maths Paper 1?
The length of GCSE Maths Paper 1 depends on the exam board and specification. For the main GCSE Maths qualifications in England, Paper 1 is typically 1 hour 30 minutes and carries 80 marks.
Students should use the time carefully, allowing enough time for both straightforward questions and the more challenging problems towards the end of the paper.
| Exam Board | Paper 1 Duration | Marks | Calculator? |
|---|---|---|---|
| AQA | 1 hour 30 minutes | 80 | No |
| Edexcel | 1 hour 30 minutes | 80 | No |
| OCR | 1 hour 30 minutes | 100 | No |
Paper 1 is generally the non-calculator paper, so practising mental arithmetic, fractions, algebraic manipulation and other non-calculator skills is particularly important before the exam.
Is GCSE Maths Paper 1 Non-Calculator?
Yes. For the main GCSE Maths exam boards in England, Paper 1 is the non-calculator paper. Students are expected to complete the paper without using a calculator, so strong mental arithmetic and written calculation skills are important.
Paper 1 can still cover a broad range of GCSE Maths topics, including number, algebra, geometry, ratio, proportion, probability and statistics. The key difference is that students need to complete calculations using mathematical methods rather than relying on a calculator.
Before the exam, practise:
- Fractions, decimals and percentages without a calculator
- Mental arithmetic and estimation
- Algebraic manipulation
- Exact values and surds
- Multi-step problem solving
- Checking whether answers are sensible
It is also useful to practise GCSE Maths Paper 1 past papers under timed conditions so you become comfortable working without a calculator.

GCSE Maths Paper 1 Topics
Number and Algebra
Number and algebra are key areas to revise for GCSE Maths Paper 1, particularly because Paper 1 is non-calculator. Students need to be confident carrying out calculations accurately while also applying algebraic methods to unfamiliar problems.
Important areas to practise include:
- Fractions, decimals and percentages
- Factors, multiples and prime numbers
- Indices and standard form
- Ratio and proportion
- Expanding and factorising expressions
- Solving linear and quadratic equations
- Sequences and nth term
- Inequalities
- Algebraic manipulation
For Paper 1, focus on completing calculations without relying on a calculator. Practise showing clear working and using exact values where appropriate, as this can make multi-step algebra and number problems much easier to manage.
Geometry and Measures
Geometry and measures are important areas to revise for GCSE Maths Paper 1, especially because students need to complete calculations without a calculator. Questions can test both your knowledge of key rules and your ability to apply them to unfamiliar diagrams.
Important areas to practise include:
- Angles and angle properties
- Properties of triangles and quadrilaterals
- Area and perimeter
- Volume and surface area
- Circle geometry
- Transformations
- Similarity and congruence
- Pythagoras’ theorem
- Trigonometry
- Bearings and scale drawings
For Paper 1, make sure you are comfortable recalling important formulas and working with exact values where possible. Drawing or annotating diagrams can also help you identify the information needed before starting a calculation.
Ratio, Proportion and Probability
Ratio, proportion and probability are important areas to revise for GCSE Maths Paper 1. Questions can range from straightforward calculations to multi-step problems where you need to identify the relationship between different quantities.
Key areas to practise include:
- Simplifying and comparing ratios
- Sharing quantities in a given ratio
- Direct and inverse proportion
- Scale factors and proportional relationships
- Probability calculations
- Sample spaces and probability diagrams
- Tree diagrams
- Expected outcomes
Because Paper 1 is non-calculator, practise working with fractions, ratios and exact values without relying on a calculator. For harder questions, write down each stage of your reasoning and check that your probabilities remain between 0 and 1.
AQA GCSE Maths Paper 1
AQA Paper 1 Format
The AQA GCSE Maths Paper 1 is the first of three exam papers and is the non-calculator paper. It is worth 80 marks and accounts for one-third of the overall GCSE Maths assessment. (AQA)
| Feature | AQA Paper 1 |
|---|---|
| Duration | 1 hour 30 minutes |
| Marks | 80 |
| Calculator | Not allowed |
| Assessment weighting | 33⅓% |
| Tier | Foundation or Higher |
| Question style | Short questions to multi-step problems |
AQA can assess any part of the GCSE Maths specification on Paper 1, so students should not expect particular topics to appear only on this paper. Questions generally become more demanding as the paper progresses. (AQA)
For Paper 1, focus particularly on non-calculator skills, including mental arithmetic, fractions, algebraic manipulation and exact calculations. AQA also advises students to show clearly how they work out their answers. (AQA)
Edexcel GCSE Maths Paper 1
Edexcel Paper 1 Format
The Edexcel GCSE Maths Paper 1 is the first of three exam papers and is the non-calculator paper. For the current specification, it is worth 80 marks. From the June 2026 exam series, Edexcel increased the time allowed for Paper 1 to 2 hours 15 minutes.
| Feature | Edexcel Paper 1 |
|---|---|
| Duration | 2 hours 15 minutes |
| Marks | 80 |
| Calculator | Not allowed |
| Tier | Foundation or Higher |
| Paper | Paper 1 (Non-Calculator) |
The paper can assess content from across the GCSE Maths specification, so students should revise the full course rather than expecting certain topics to appear only on Paper 1. Questions can include straightforward calculations as well as multi-step problem-solving and mathematical reasoning.
When practising Edexcel GCSE Maths Paper 1, use older past papers for question practice but allow the current 2-hour-15-minute timing when simulating the 2026 exam and beyond. Pearson confirms that the increase in time does not change the other aspects of the paper.
How to Prepare for GCSE Maths Paper 1
Practise Paper 1 Questions
Regularly practising GCSE Maths Paper 1 questions is one of the best ways to prepare for the non-calculator exam. It helps you become familiar with exam-style questions while improving your ability to solve problems without relying on a calculator.
Start with individual questions by topic, then progress to mixed-question practice as your confidence improves. Focus particularly on:
- Mental arithmetic and calculations
- Fractions, decimals and percentages
- Algebraic manipulation
- Ratio and proportion
- Geometry and measures
- Multi-step problem solving
After each practice session, mark your answers carefully and make a note of any questions you found difficult. Revisit the relevant topic and try a similar question before moving on.
Once you are comfortable with individual questions, complete full Paper 1 past papers under timed conditions. This will help you improve both accuracy and time management before the real exam.
Review Your Mistakes
Reviewing your mistakes is one of the most effective ways to improve your performance in GCSE Maths Paper 1. Instead of simply moving on after marking a paper, use incorrect answers to identify the topics and methods that need more practice.
After completing a Paper 1 practice paper:
- Check every incorrect answer and identify where your method went wrong.
- Look for patterns in your mistakes, such as calculation errors or difficulty with algebra.
- Revisit the relevant topic and review the method.
- Redo the question without looking at the solution.
- Try a similar question to check that you can apply the method independently.
Keep a record of recurring mistakes and return to them during revision. This helps turn each GCSE Maths Paper 1 practice session into targeted revision rather than simply another test.
Improve Non-Calculator Skills
Improving your non-calculator skills is essential for performing well in GCSE Maths Paper 1. Without a calculator, you need to be confident completing calculations accurately and choosing efficient methods.
Focus on practising:
- Mental arithmetic: Build speed with addition, subtraction, multiplication and division.
- Fractions: Practise simplifying, adding, subtracting, multiplying and dividing fractions.
- Percentages: Calculate common percentages without relying on a calculator.
- Algebra: Become confident simplifying expressions and solving equations.
- Exact values: Work with surds, indices and other exact forms where required.
- Estimation: Use estimation to check whether your answers are reasonable.
Regular short practice sessions can improve both speed and accuracy, making it easier to manage the non-calculator questions under exam conditions.
