CAT 2026 QA: Quick Facts First

CAT 2026 is expected to be held on Sunday, 29 November 2026, with the official notification anticipated around 26 July 2026 and registration opening in early August. IIM Indore is expected to conduct the exam on a rotational basis, though this is confirmed only when the notification releases. Always verify dates on the official website, iimcat.ac.in.

Before we rank the most important CAT Quant topics, anchor your strategy to the section structure (based on the CAT 2025 pattern):

• Questions in QA: 22
• Sectional time limit: 40 minutes (53 minutes 20 seconds for eligible PwD candidates)
• Marking scheme: +3 for each correct answer; −1 for each incorrect MCQ
• TITA (Type-In-The-Answer): no negative marking
• Total paper: approximately 68 questions across three sections (VARC, DILR, QA) in CAT 2024–2025

Note: IIMs do not publish an official CAT syllabus. The priorities below reflect Supergrads analysis of CAT QA sections from 2019–2025 and past-paper trends - treat them as revision guidance, not a guaranteed blueprint. Exact question counts vary by slot and year. Final CAT 2026 pattern details are confirmed only in the official notification.

Which Is the Most Important CAT Quant Topic?

Arithmetic - specifically Time & Work, Time-Speed-Distance, and Percentage-based topics, is the highest-yield area of CAT Quant, typically contributing the largest share of QA questions in recent CAT slots. Algebra (identities, quadratics, indices, and logarithms) follows closely and is often more predictable. The most reliable strategy is to secure Arithmetic first, then lock in Algebra. You can explore the full CAT Quantitative Aptitude syllabus for the complete scope.

Top 10 Most Important CAT Quant Topics for 2026

1. Arithmetic (Highest Priority)

Expected Questions: 8–10

Difficulty: Easy to Moderate

Arithmetic consistently dominates CAT Quant and remains the single most important area to prepare. If you are short on time, this is where your CAT preparation should begin.

Key Subtopics:

• Percentages
• Profit & Loss
• Simple & Compound Interest
• Ratio & Proportion
• Averages
• Mixtures & Alligations
• Time, Speed & Distance
• Time & Work
• Pipes & Cisterns

Why it matters: Arithmetic syllabus questions are generally calculation-light but concept-heavy. Strong conceptual clarity and consistent practice can help you solve these questions quickly and accurately.

2. Algebra

Expected Questions: 5–7

Difficulty: Moderate

Algebra is another high-weightage topic in CAT Quant. Questions often test conceptual understanding rather than lengthy calculations.

Key Subtopics:

• Linear Equations
• Quadratic Equations
• Functions
• Logarithms
• Indices & Surds
• Inequalities
• Progressions

Why it matters: Mastering Algebra helps in solving a significant portion of CAT Quant questions while also improving logical thinking.

3. Geometry & Mensuration

Expected Questions: 3–4

Difficulty: Moderate to Hard

Geometry requires strong conceptual understanding and visualisation skills. Most questions are based on standard properties and theorems.

Key Subtopics:

• Triangles
• Circles
• Quadrilaterals
• Polygons
• Coordinate Geometry Basics
• Area & Perimeter
• Volume & Surface Area

Why it matters: Geometry questions often reward students with clear fundamentals rather than advanced mathematics.

4. Modern Mathematics

Expected Questions: 2–3

Difficulty: Moderate

Although Modern Mathematics carries relatively fewer questions, they are generally scoring if the concepts are well understood.

Key Subtopics:

• Permutations & Combinations
• Probability
• Set Theory
• Binomial Theorem

Why it matters: These questions are often formula-based and become easy to solve with regular practice.

5. Number System

Expected Questions: 1–2

Difficulty: Moderate

While Number System contributes fewer questions, it forms the foundation of several Quant topics and frequently appears in combination with Algebra and Arithmetic.

Key Subtopics:

• Divisibility Rules
• Factors & Multiples
• HCF & LCM
• Remainders
• Factorials
• Base Systems

Why it matters: A strong understanding of Number System concepts improves problem-solving speed across multiple CAT Quant topics.

1. Time and Work

Time and Work is a high-value chapter. Across the last five to six years of CAT papers, you will typically find questions from this area in almost every slot. Common trap: mixing up work-rate addition when efficiencies differ - always convert to a common unit of work first. Focus on efficiency-based problems, individual work rates, and group efforts.

Practice set: Time and Work CAT questions

2. Time, Speed, and Distance

Another essential Arithmetic chapter, with two to three questions commonly expected. Common trap: average speed for equal distances is the harmonic mean, not the arithmetic mean of the two speeds. Cover trains, boats and streams, races, and relative-speed scenarios thoroughly.

Practice set: Time, Speed and Distance CAT questions

3. Averages, Mixtures, and Alligations

These closely related CAT Quant topics often yield questions built on weighted averages and the combining of quantities or solutions. Common trap: apply the alligation ratio to the differences between values, not the raw quantities. They are doable and offer strong scoring potential.

Practice set: Averages CAT questions

4. Ratio, Proportion, and Partnership

A fundamental chapter you can expect to see in the exam. The questions are often straightforward with disciplined practice, and the concepts support partnership profit-sharing and many other QA problems. Common trap: align time periods before splitting partnership profits.

Practice set: Ratio and Proportion CAT questions · Partnership questions

5. Percentages, Profit, Loss, Discount, Simple and Compound Interest

This cluster is built on the concept of percentages. Expect two to three questions in total. Common trap: successive percentage changes are multiplicative, not additive. Mastering percentages makes profit-loss, discount, and interest problems significantly easier.

Practice set: Percentage CAT questions

6. Algebraic Identities

Algebraic identities appear frequently across CAT slots, directly or indirectly. Knowing your formulas - such as (a+b)², (a−b)², a²−b², and (a+b)³ - and applying them quickly can simplify otherwise lengthy problems. Common trap: forcing expansion where a clean identity would collapse the expression in one step.

Practice set: CAT Algebra questions · Algebra topics for CAT

7. Indices, Surds, and Logarithms

Expect one to three questions from this rule-based group. Once you are fluent with the laws of exponents, roots, and logarithms, these become reliable scoring opportunities. Common trap: mishandling base changes and sign rules in logarithmic simplification.

Practice set: CAT Logarithm questions with answers

8. Linear Equations

A basic yet important part of algebra. Even when mixed with other concepts, you can usually expect at least one question rooted in linear equations. Common trap: careless setup when translating word problems into equations. Be comfortable with single- and multi-variable systems.

9. Quadratic Equations

Quadratics follow linear equations in importance and appear regularly. Understand how to find roots, the relationship between coefficients and roots, and the standard solution forms. Common trap: ignoring the discriminant when the question turns on the nature of the roots.

Practice set: CAT Maths questions

10. Modulus-Based Equations

Modulus questions can be tricky without a firm grasp of the absolute-value concept. Expect at least one such question, often interwoven with linear and quadratic ideas. Common trap: dropping a case when splitting the modulus into positive and negative intervals.

Practice set: CAT Modulus questions

Scope note: Other CAT Quant topics - Geometry, Mensuration, and Number System - also appear in QA. This list reflects the highest-ROI chapters for a focused revision window, not the complete QA scope. Once these 10 are secure, extend to the remaining topics if time allows. For the full topic bank, see CAT Quantitative Aptitude questions.

Do These CAT Quant Topics Help in Other MBA Exams?

These fundamentals also underpin the Quant sections of XAT, NMAT, and SNAP. However, each exam differs in difficulty, question count, and style, so calibrate your practice to the specific exam rather than assuming CAT-level preparation transfers directly. For a structured comparison, see whether CAT preparation is enough for XAT and explore XAT time and work questions.

CAT Mock-Test & Revision Routine

Take sectionals and full-length mocks at your actual CAT slot time to train focus and stamina.

After every mock, run this routine:

1. List every error and categorise it as concept, calculation, or time pressure.
2. Check whether the same silly mistakes repeat in specific CAT Quant topics.
3. Re-solve those questions without a timer for conceptual clarity.
4. Learn the full method in our guide on how to analyse CAT mock tests.

Core 15-Day CAT Quant Strategy: The 4-Step Plan

Use this compressed plan only if you are in the final fortnight before CAT 2026.

1. Prioritise and Segment Topics

Spend 75–80% of revision on the high-frequency CAT Quant topics above - Arithmetic, Algebra, and Number System. Cap less-frequent subtopics at 20–25%.

2. Maintain a Formula and Error Logbook

Build a CAT Quant formula sheet and review it daily. Track silly mistakes and why they occur.

3. Practise with Purpose

Avoid random sets. Work through CAT previous-year question papers under strict timing. Aim for 5–7 full-length or sectional QA mocks at your actual slot time, revising only your top weaknesses before the next test.

4. Master Test-Day Tactics

Attempt familiar CAT Quant topics first (usually Arithmetic and Algebra). If a question resists you after 2–3 minutes, mark and move on. Target 80–85% accuracy in your first 10–12 questions to build momentum. See more CAT last-minute preparation tips and the full how to crack CAT in 15 days plan.

How to Maximise Your CAT QA Score in 2026

Focused revision of these 10 most important CAT Quant topics lets you approach a meaningful share of the 22 QA questions with confidence. Strong accuracy on your comfort topics supports a competitive sectional percentile - but remember that percentile depends on overall paper difficulty and slot normalisation.

A high QA percentile helps you clear sectional cutoffs and qualify for the shortlist; it does not by itself guarantee an IIM call or final conversion. Final selection depends on your overall score, category, and each institute's separate shortlisting and interview criteria - see the IIM selection criteria and CAT cut-off for IIM for details. Once results are out, gauge your chances with the CAT percentile predictor.

In your remaining days:

• Solve with focus across all 10 CAT Quant topics rather than chasing volume.
• Review formulas and shortcuts daily from your formula sheet.
• Analyse previous-year papers to internalise question types and difficulty.

Conclusion

Your final-phase edge in CAT Quant comes from selection, not sheer volume. Revise these 10 most important CAT Quant topics until they are automatic, log every error by cause, and let your last five to seven analysed mocks decide where the remaining hours go. Convert what you know first - reliable accuracy on your strong topics beats rushed guessing across all 22 questions.

Next in your CAT 2026 journey: once your QA is on track, prepare for the CAT GDPI stage so you are ready the moment results arrive.
