Edexcel Maths: papers and exam technique — Edexcel GCSE Maths revision

Paper structure and tiers

• Maths GCSE is split into a non-calculator paper and calculator papers — always check which paper you're sitting before you start.
• Foundation tier covers grades roughly 1-5; Higher tier covers grades roughly 4-9, with an overlap zone around grades 4-5.
• Choose the tier your teacher recommends based on mock performance — sitting too high a tier risks a very low grade.
• Some questions appear on both tiers with slightly different numbers or extra parts on Higher.
• Always check the current specification and sample assessment materials on your exam board's own website, since paper arrangements and question styles can change between series.

Method marks and showing working

• Marks are awarded for correct method even if the final answer is wrong, so always write down every step.
• Never rub out working — cross it out lightly if you change your mind, examiners can still credit it.
• Label each stage of a multi-step calculation so the examiner can follow your logic.
• If a question says 'show that', you must demonstrate the process algebraically or numerically, not just state the result.
• Write formulae before substituting numbers into them, since this alone can earn a method mark.

Key terms

Non-calculator paper

A paper where no calculator is allowed, testing manual arithmetic and algebra skills.

Calculator paper

A paper where a calculator is permitted, often used for problems with awkward numbers.

Tier of entry

Foundation or Higher — determines which grades are available to a candidate.

Method mark

A mark awarded for correct working or approach, independent of the final answer.

Accuracy mark

A mark awarded only for a fully correct final answer.

Show that

An instruction requiring full working to prove a given statement or value.

Common exam traps

• Rounding too early in a multi-step calculation, causing the final answer to be marked wrong.
• Forgetting to check units, especially converting between cm and m or minutes and hours.
• Leaving an answer as an improper fraction or unsimplified ratio when asked for simplest form.

Practice questions with answers

1. 1. On a non-calculator paper, what should you rely on most for a fraction calculation?

   • • Guessing
   • • Written method with common denominators
   • • A phone calculator
   • • Rounding to whole numbers

   Answer: Written method with common denominators

   Without a calculator, use manual methods like finding common denominators to work accurately.

2. 2. Work out 3/4 + 1/6 without a calculator.

   Answer: 11/12

   Common denominator 12: 9/12 + 2/12 = 11/12.

3. 3. A question says 'show that x = 5 is a solution'. What must you do?

   • • Just write x = 5
   • • Substitute x = 5 and show both sides are equal
   • • Guess and check nothing
   • • State the answer only

   Answer: Substitute x = 5 and show both sides are equal

   'Show that' requires full working demonstrating the statement is true, not just the answer.

4. 4. Give 7.849 correct to 2 decimal places.

   Answer: 7.85

   The third decimal digit is 9, so round the second digit up: 7.85.

5. 5. A ratio question asks to simplify 15:20. What is the simplest form?

   • • 3:4
   • • 15:20
   • • 5:4
   • • 1:2

   Answer: 3:4

   Divide both parts by the highest common factor, 5: 15÷5=3, 20÷5=4.
