2 min read

With the non‑calculator exam approaching, it’s crucial to understand which topics are most likely to appear and how to revise effectively. The non‑calculator paper tests method, reasoning, accuracy, and core mathematical understanding, not just mental arithmetic.

1. Number & Algebra

Number and algebra make up a large proportion of the non‑calculator paper.

Essential Number Skills

Long multiplication & long division
Percentages & ratios
Indices (including fractional & negative powers)
Standard form (multiply, divide, convert)
Percentage calculations without a calculator
Fraction arithmetic (proper, improper, mixed)
Fractions of amounts
Converting between fractions, decimals, percentages
Estimation & approximation (rounding to 1 s.f.)
Product of primes
HCF & LCM using Venn diagrams
Surds (simplifying, multiplying, dividing, rationalising)
Converting recurring decimals to fractions

Key Algebra Skills

Simplifying expressions
Solving equations
Quadratic factorisation
Completing the square
Substitution
Sequences

2. Geometry & Measures

This section focuses on shape properties, exact values, and formula fluency. As the document explains, you’ll need confidence with Pythagoras, trigonometry, and circle formulae.

Key Geometry Topics

Exact trig values (0°, 30°, 45°, 60°, 90°)
Pythagorean triples (3‑4‑5, 5‑12‑13, and multiples)
Area & circumference of circles (in terms of π)
Volume & surface area of 3D shapes (in terms of π)

3. Statistics & Probability

Statistics and probability questions may appear on either paper, but several topics are especially common on Paper 1.

Key Topics

Tree diagrams (often in fractional form)
Reading statistical graphs
Cumulative frequency
Histograms
Box plots

4. Types of Questions

Worded Problems

These require careful reading, identifying key information, and showing clear working.

Graph & Table Interpretation

Expect to interpret data, calculate averages, compare values, and use units correctly.

Fractions, Decimals & Percentages

You’ll need to convert between forms and perform operations without a calculator.

Algebraic Manipulation

Simplifying, solving, factorising, rearranging, and sometimes proving results.

“Prove algebraically that the difference between the squares of any two consecutive integers is equal to the sum of these two integers.”

Geometry & Measures

Area, perimeter, volume, angles, Pythagoras, and circle calculations.

5. How to Revise Effectively for the Non‑Calculator Paper

Create a Study Schedule

Plan your revision time and include breaks to avoid burnout.

Practise Past Questions

Work through a variety of questions to build familiarity with the style and difficulty.

Use Worked Examples

Study examples from textbooks or revision guides to reinforce methods.

Identify Weak Areas

Focus on the topics you find most challenging.

Stay Positive

Stay positive, keep practicing, and don’t let setbacks get you down.

Additional Tips

Make flashcards for formulas
Look after your physical and mental wellbeing
Practise consistently

Conclusion

The non‑calculator paper rewards strong methods, clear reasoning, and solid number and algebra skills. By focusing on the key topics above and practising regularly, you can approach the exam with confidence.
