Cambridge O Level Maths Tutors Online

Cambridge O Level Mathematics (Syllabus D) is syllabus 4024. This page works from the syllabus for exams in 2025, 2026 and 2027, version 2. Exams are available in the June and November series.

All candidates take two components, and all candidates are eligible for grades A* to E. The grade range stops at E rather than running to G, and anything below E is ungraded. There is no Core and Extended tier, so every student sits the same two papers and is graded across the same range. There is no easier route to fall back on, and no ceiling to break through either.

Paper 1 is the non-calculator paper. It lasts 2 hours, carries 100 marks and is worth 50% of the qualification, and it consists of structured and unstructured questions. Use of a calculator is not allowed.

Paper 2 is the calculator paper. It also lasts 2 hours and carries 100 marks and 50%, and it consists of structured and unstructured questions. Candidates should have a scientific calculator for this paper.

So the two papers are identical in length and marks, and the only difference is the calculator. That makes the non-calculator paper a genuine skill in its own right rather than a warm up, and it is where many students lose marks they did not expect to lose. It is not a test of mental arithmetic for its own sake. It is a test of whether a student can work fluently with fractions, surds, indices, standard form and exact values without reaching for a machine.

The subject content is organised into nine topics: Number, Algebra and graphs, Coordinate geometry, Geometry, Mensuration, Trigonometry, Transformations and vectors, Probability, and Statistics. The syllabus notes that the content is organised by topic and is not presented in a teaching order, so schools plan their own sequence, and that learners are expected to use the listed techniques to solve problems with or without a calculator as appropriate.

One detail is worth knowing before revising: a List of formulas is provided on page 2 of the examination papers for candidates to refer to during the examination. So the exam is not a memory test for formulas, and revision should focus on recognising which formula a question needs and using it correctly rather than reciting it.

The syllabus also states that learners should pursue an integrated course that allows them to develop their skills and understanding both with and without the use of a calculator. That is an instruction about how the course should be taught, and it explains why the two papers are built the way they are.

The assessment objectives are two. AO1 is knowledge and understanding of mathematical techniques, covering recalling and applying mathematical knowledge and techniques, carrying out routine procedures in mathematical and everyday situations, understanding and using mathematical notation and terminology, performing calculations with and without a calculator, organising, processing, presenting and understanding information in written form, tables, graphs and diagrams, estimating and approximating and working to degrees of accuracy appropriate to the context and converting between equivalent numerical forms, understanding and using measurement systems in everyday use, measuring and drawing using geometrical instruments to an appropriate degree of accuracy, and recognising and using spatial relationships in two and three dimensions.

AO2 is analyse, interpret and communicate mathematically, covering analysing a problem and identifying a suitable strategy to solve it including using a combination of processes where appropriate, making connections between different areas of mathematics, recognising patterns in a variety of situations and making and justifying generalisations, making logical inferences and drawing conclusions from mathematical data or results, and communicating methods and results in a clear and logical form.

The weightings are given as ranges rather than fixed figures. AO1 is 40 to 50 per cent of the qualification and AO2 is 50 to 60 per cent, and the per component tables are the same for both papers. So analysis, interpretation and communication carry the larger share, and they carry it equally on the calculator paper and the non-calculator paper.

That balance is worth understanding. More than half of the marks reward strategy, connection and clear explanation rather than routine procedure. A student who can execute methods accurately but cannot choose between them, link topics or explain a result will find the ceiling lower than their technique suggests.

The qualification is graded A*, A, B, C, D or E, with A* the highest and E the lowest. A candidate whose performance does not meet the standard required for grade E is ungraded, which is reported on the statement of results but not on the certificate.
