Key takeaways
- Start with calculation fluency and arithmetic; almost every other topic leans on them.
- Arithmetic and algebra usually give the most marks per hour of study.
- Geometry, number system and modern maths reward steady practice rather than cramming.
- Revise formulas daily in small doses; do not rely on a big revision at the end.
CAT Quantitative Ability (QA) has no official syllabus list, but its question areas are consistent: arithmetic, algebra, geometry and mensuration, number system and modern maths. The order in which you learn them matters. A sensible order builds the skills that later topics depend on, so you are not stuck relearning basics in the middle of a difficult chapter.
Stage 1: Calculation fluency and basic arithmetic
Before you open a single advanced chapter, make sure you can handle fractions, percentages, ratios and approximate calculations quickly. Practise tables, squares and common fractions until they are automatic. Then cover percentages, profit and loss, ratio and proportion, averages, mixtures and alligation, simple and compound interest, and time, speed and distance, time and work. These are the foundations for most word problems.
Stage 2: Algebra
Linear and quadratic equations, inequalities, functions, logarithms, progressions and basic modulus problems come next. Algebra is where clean fundamentals pay off, because a small slip early in a problem cascades to a wrong answer. Learn the standard identities and the discriminant, and practise setting up equations from words.
Stage 3: Number system
Divisibility, remainders, factors, HCF and LCM, and unit digits form a compact topic with a limited set of ideas. Once you see the patterns (cycles of remainders, factor counting from prime powers), questions that look unfamiliar become routine.
Stage 4: Geometry and mensuration
Triangles, circles, polygons, coordinate geometry and the formulas for areas and volumes. Geometry takes the most practice per mark because each problem needs a good diagram. Learn the standard results and recognise the common right-angled triples so you can skip calculations.
Stage 5: Modern maths
Permutations and combinations, probability, and set theory. These rely on logical counting rather than formulas, so practise a variety of problems and always ask what the cleanest way to count is.
| Topic area | Typical weight in recent papers | Study approach |
|---|---|---|
| Arithmetic | Large share | Daily practice of mixed word problems |
| Algebra | Large share | Learn identities; solve many equation setups |
| Number system | Moderate share | Learn patterns and prime factorisation |
| Geometry and mensuration | Moderate share | Draw diagrams; memorise key results |
| Modern maths | Smaller share | Practise counting and probability patterns |
The weight column is a rough guide based on how recent papers have looked; the exact split varies from year to year. Use it to decide where to spend more time, not to skip a topic.
How to practise each stage
- After learning a topic, solve 20 to 30 questions on it without a timer, then 15 under a timer.
- Keep an error log with the reason for every mistake (concept gap, calculation slip or time).
- Use short daily revision of formulas. Our CAT flashcards cover the key Quant formulas and shortcuts.
- Mix topics in the last two months with sectional Quant tests and then the full-length mock.
