A complete guide to Cambridge IGCSE Maths

GCSEMathsSubject Guides12 min readBy Tom Mercer

Cambridge IGCSE Mathematics (specification 0580) is the international equivalent of GCSE Maths, run by Cambridge Assessment International Education. It is sat by students at international schools worldwide and by many UK independent schools. The course covers the standard areas of school maths and is assessed across four papers.

This guide walks through everything you need to know to sit the exam with confidence: How the papers are structured, the difference between Core and Extended tiers, what each paper covers, and the revision techniques that work best for Cambridge IGCSE maths.


Four papers, mix of calculator and non-calculator

Two papers per tier: One non-calculator and one calculator. Both are required.

Core or Extended tier

Core route covers grades C to G. Extended route covers grades A* to E and includes additional content.

Recognised worldwide

Accepted by universities in the UK, US, Canada, Australia, and across Europe and Asia as equivalent to UK GCSE.


How Cambridge IGCSE Maths is assessed

Cambridge IGCSE Maths is fully linear. All papers are sat at the end of the course, in either May/June or October/November. There is no coursework and no controlled assessment.

The qualification is tiered. Core students sit Papers 1 and 3 and have access to grades C to G. Extended students sit Papers 2 and 4 and have access to grades A* to E. Within each tier, the two papers split 50/50 – one non-calculator and one calculator – and both are required. Your school decides which route to enter you for based on mocks and class performance.

Core vs Extended The Core route suits students aiming for grades C to G. The Extended route is for students aiming for A* to E. Extended covers everything in Core plus more advanced content including trigonometry, calculus introduction, vectors, and functions.

Topics covered

The Cambridge IGCSE Maths specification is grouped into nine topic strands. Together they cover the breadth of school-level mathematics.

1. Number

Integers, fractions, decimals, percentages, ratio and proportion, indices, standard form, surds (Extended), bounds, and number sense.

2. Algebra and graphs

Expressions, equations, inequalities, sequences, graphs, simultaneous equations, quadratic equations, and function transformations. Extended includes harder factorising, completing the square, and the quadratic formula.

3. Coordinate geometry

Plotting graphs, gradients, intercepts, equations of straight lines, parallel and perpendicular lines, and midpoints.

4. Geometry

Angles, triangles, polygons, congruence, similarity, circle theorems (Extended), and constructions.

5. Mensuration

Area, perimeter, volume, surface area, arcs and sectors, and compound shapes.

6. Trigonometry

Pythagoras, sine, cosine, and tangent in right-angled triangles. Extended adds the sine rule, cosine rule, area of a triangle, and 3D trigonometry.

7. Transformations and vectors

Reflection, rotation, enlargement, translation, and combined transformations. Extended includes vector notation, addition, scalar multiplication, and vector geometry.

8. Probability and statistics

Averages, range, charts, scatter diagrams, frequency tables, probability, tree diagrams, and (Extended) conditional probability and cumulative frequency.

9. Functions (Extended only)

Function notation, composite functions, inverse functions, and graphs of functions. This is one of the main differences from UK GCSE.

Tip

Exam tip for both papers Cambridge examiner reports consistently flag algebraic fractions, vectors, and trigonometry beyond right-angled triangles as the topics where Extended candidates lose the most marks. Build a weekly rotation that returns to each of these every fortnight.

Key facts and formulae

Cambridge prints a short formula list at the front of Papers 2 and 4 covering common geometry and trigonometry formulae. However, many formulae are NOT given and must be memorised. These include the quadratic formula, the rules of indices, and the basic trig ratios.

Formulae you must memorise (Extended tier)

  • The quadratic formula
  • Sin, cos, tan ratios in right-angled triangles
  • Pythagoras' theorem
  • Rules of indices
  • Area of a triangle = ½ab sin C
  • Sine and cosine rules (given on Paper 4 but worth memorising)
  • Volume and surface area formulae for cones, spheres, cylinders
  • Compound interest formula
Good to know

Where students lose marks The two biggest sources of lost marks are arithmetic slips on the non-calculator paper and missing units on geometry questions. Always check working line by line and label every final answer with its units.

Grading and tier choice

Cambridge IGCSE Maths is graded A* to G. Core gives access to grades C to G. Extended gives access to A* to E. There is overlap in the middle, so a strong Core candidate can earn a C and a weaker Extended candidate can earn an E or D.

Most academically strong students take Extended because it unlocks the higher grades and is the route accepted as equivalent for top universities and sixth forms. Your school will normally choose the route based on mocks.

Grade boundaries shift every series and are published by Cambridge on results day each August and January.

5 tips for Cambridge IGCSE Maths revision

Maths is the most practice-driven subject at IGCSE. The students who get A* are not necessarily the most naturally talented, but the ones who have done the most varied past paper practice and built fast, accurate technique on every topic.

1. Do at least one past paper a week

By the time you sit the real exam, you should have done at least twelve full Cambridge IGCSE Maths past papers under timed conditions. There is no substitute for repeated exposure to the question style and pacing.

2. Drill the non-calculator paper separately

Many students get caught out by Paper 1 or Paper 2 because they have done all their practice with a calculator. Set aside a weekly session that is non-calculator only. Long multiplication, fraction arithmetic, and percentage calculations need fluency.

3. Master your calculator for the calculator paper

Learn the fraction, surd, statistics, and table modes on a Casio fx-83 or fx-991. Many students lose marks because they cannot enter a calculation cleanly under exam pressure. The calculator paper carries the same weight as the non-calculator paper, so fluency here matters.

4. Write working out, even on easy questions

Cambridge awards method marks for clear working. If your final answer is wrong but your working shows the right approach, you can still pick up most of the marks. Train this habit on every question, not just the hard ones.

5. Track your weak topics in a single sheet

Every time you drop marks on a past paper, write the topic on a tracker. The same topics will keep coming up. The biggest grade jumps come from fixing recurring weaknesses, not from churning more papers.
