How Hard Is CEnT-S Maths? A Curriculum Map

Map the official topic headings to A-level, IB Mathematics and Indian school maths, with important gaps and curriculum differences made explicit.

Key Takeaways
Use the official topic list, not a label such as “A-level difficulty”. Familiar content can still take time to solve.
IB courses differ. Analysis and approaches and Applications and interpretation do not have identical coverage.
Earlier school content still matters. Percentages and elementary geometry do not become irrelevant when you reach calculus.

The CISIA maths syllabus is the checklist for what to study. The mapping below is our editorial comparison of topic coverage, not an official qualification equivalence or a prediction of your score.


Which curricula are being compared?

For UK readers, we use the Department for Education A-level Mathematics content for England. Other UK jurisdictions and international A-level boards can differ. “Earlier” means a skill normally developed before the qualification and then used within it.

For IB, the main reference is the Mathematics: analysis and approaches guide, including its distinction between SL and additional HL content. The IB's official mathematics alignment study also identifies differences from Applications and interpretation (AI). Check the guide for your assessment year: one IB course name cannot stand for all four SL/HL routes.

For India, the reference is school Mathematics (041), not every state board or Applied Mathematics course. The Delhi Directorate of Education's 2026–27 Class XI syllabus explicitly refers readers to CBSE's senior-secondary curriculum. Your own board and current syllabus remain the final check.

Topic-by-topic revision map

The first column follows CISIA's seven maths headings. The other columns indicate where to look for revision, including gaps that require separate work.

CISIA topicA-level route: EnglandIB MathsIndian Mathematics (041) route
Numbers: arithmetic, factors, powers, roots, percentagesMostly earlier GCSE foundations; rational indices and surds also appear in AS/A-level algebra.Prior learning and AA number/algebra. Do not assume basic arithmetic is automatically fluent.Mostly before Class XI; revise earlier arithmetic rather than searching only XI–XII chapters.
Algebra: expressions, polynomials, equations, inequalities and systemsGCSE foundations plus AS algebra, quadratics and simultaneous equations.AA algebra/functions; check inequalities separately, especially in AI.Earlier algebra plus XI quadratics and linear inequalities. CISIA's quadratic inequalities need explicit practice beyond the XI linear-inequality heading.
Geometry: plane and solid figures, similarity, coordinates, lines and circlesElementary shapes and volumes are mostly GCSE; line and circle equations are in AS coordinate geometry.Earlier geometry plus AA geometry. The circle-equation requirement needs a separate check against your course; do not infer it from the word “geometry”.Earlier mensuration and similarity; XI straight lines and conics include circle equations.
Functions: composition, inverses, graphs and transformationsAS graphs and transformations; composition and inverse functions are in full A-level content.AA functions, including reciprocal and rational graphs. AI students should check symbolic work, inverses and transformations individually.XI functions and graphs; the cited XI document marks composition as formative only. Check your XII course for inverses and practise transformations separately.
Exponentials and logarithmsAS exponentials/logarithms and related equations.AA number/algebra and functions. AI coverage differs in algebraic depth.XI lists exponential and logarithmic functions and graphs. Practise CISIA-style equations and inequalities explicitly; recognising a graph is insufficient.
Combinatorics and probabilityBasic probability overlaps; general permutations and combinations are not a named requirement of the core DfE A-level content. Study counting separately.Basic probability overlaps. General permutations/combinations are AA HL content, beyond AA SL's required list; the IB comparison identifies them as absent from AI.XI permutations, combinations and probability; extend to independent events as required by CISIA and your later school course.
Basic statistics: data displays, frequencies, averages and measurement scalesEarlier statistics plus AS data interpretation. Check nominal/ordinal/interval/ratio vocabulary separately.Prior learning and statistics/probability; check measurement-scale terminology separately.Earlier averages and graphs; XI statistics extends into dispersion. Do not substitute advanced formulae for elementary data interpretation.

What might you need beyond your own course?

An AA SL student should not assume that taking IB Maths covers the named counting methods. An AI student should check symbolic inequalities as well as counting: the IB's alignment report flags both as differences. An A-level student should add general counting methods to their checklist instead of assuming the binomial theorem covers every permutation problem.

For Indian students, the cited XI syllabus is not proof that every CISIA skill is assessed in the same way. Formative-only content, earlier geometry and later topics all need attention. A commerce student taking Applied Mathematics should compare their own syllabus rather than treating the Mathematics (041) column as a coverage guarantee.

Calculus is not a named topic in CISIA's current maths list. You do not need to complete an entire A-level, IB HL or Class XII calculus course just to begin CEnT-S preparation. Conversely, studying calculus does not establish fluency with the earlier topics the test names. Trigonometric ratios can still be useful in geometry and physics; distinguish that from assuming a separate advanced trigonometry unit in the maths syllabus.

Turn the map into a study plan

For each row, attempt a fresh problem and explain your method. Mark whether the obstacle is missing knowledge, slow manipulation or an English term. Revisit only the relevant school chapter, then try another problem without copying the worked solution.

When untimed work becomes reliable, practise the maths section's 15 questions in 30 minutes. Those counts come from CISIA, not from a curriculum equivalence. Start with our worked section examples or inspect the CEnT-S course. No average-score or pass-rate claim is needed to identify your next topic.
