CAT Quant Strategy: Important Topics & How to Prepare

Quantitative Aptitude (QA) scares a lot of CAT aspirants — especially non-engineers. But QA is the most predictable section: the syllabus is finite, and a large share of questions come from a few high-weightage areas. With the right focus, anyone can score well.
Topics that matter most
| Area | Approx. weight | Notes |
|---|---|---|
| Arithmetic | Highest | Percentages, ratio, TSD, profit & loss, mixtures — master this first |
| Algebra | High | Equations, functions, inequalities, logarithms |
| Geometry & Mensuration | Medium | Triangles, circles, coordinate geometry |
| Number Systems | Medium | Factors, remainders, divisibility |
| Modern Maths | Lower | P&C, probability, set theory |
If you are short on time, prioritise Arithmetic and Algebra — together they cover the majority of the section.
How to prepare
1. Build concepts before speed
Don't rush to timed practice. First make sure each concept is solid — a shaky fundamental costs you under exam pressure.
2. Practise in topic sets, then mixed sets
Start topic-wise to build mastery, then move to mixed timed sets that mirror the real exam's unpredictability.
3. Keep an error log
Every wrong question goes in a notebook with the reason — silly mistake, concept gap, or calculation error. Reviewing this weekly is the fastest way to raise accuracy.
