CAT 2026 QA Chapter-Wise Weightage: High-Priority Topics

Arithmetic accounts for the highest share of CAT 2026 Quantitative Aptitude questions — approximately 35–40% of the section — followed by Algebra at 25–30%, making these two areas the highest-priority topics for QA preparation.

The CAT 2026 QA section will have 22 questions to be attempted in 40 minutes. Based on trends from CAT 2021 to CAT 2024, specific chapters consistently carry higher weightage each year. Understanding this distribution helps you allocate study time strategically and target a higher percentile.

• Arithmetic (35–40%): TSD, Time and Work, Percentages, Profit-Loss, and Mixtures dominate this section every year.
• Algebra (25–30%): Quadratic Equations, Progressions, and Functions appear regularly across recent papers.
• Geometry and Mensuration (14–23%): Triangles, Circles, and Mensuration are tested every year.
• Number System (9–18%): Remainders, Factors, and Divisibility rules are high-yield topics.
• Modern Math (5–9%): Permutation and Combination and Probability appear in 1–2 questions per paper.

CAT 2026 QA Section Overview

The Quantitative Aptitude section of CAT 2026 tests mathematical reasoning across five broad topic areas. Based on the pattern observed from CAT 2021 to CAT 2024, the QA section structure is as follows:

Since TITA questions carry no negative marking, they are strategically important — even an educated guess on a TITA question does not cost you marks. This pattern has remained consistent across CAT 2021 to CAT 2024 and is expected to continue for CAT 2026.

CAT QA Chapter-Wise Weightage: Trends from 2021–2024

The table below shows the approximate number of questions from each topic area based on CAT 2021, 2022, 2023, and 2024 paper analysis. Use this distribution to identify where to invest the most preparation time for CAT 2026.

Arithmetic and Algebra together account for roughly 55–70% of all QA questions each year — mastering these two areas is the single biggest lever for improving your QA score in CAT 2026.

Topic-Wise Preparation Tips for CAT 2026 QA

Knowing the weightage is only part of the strategy. Here is how to prepare each high-priority area most efficiently for CAT 2026.

• Arithmetic (Highest Priority): Practise TSD and Time and Work through scenario-based problems — CAT typically frames these with boats, trains, and pipes variations. Target at least 15–20 problems per sub-topic before attempting full mocks.
• Algebra: Progressions and Functions in CAT are concept-heavy rather than calculation-heavy. Focus on identifying the correct formula or approach quickly and practise from actual CAT previous year papers.
• Geometry: Learn all standard theorems for triangles and circles. CAT geometry problems often require combining two theorems — practise mixed problems rather than isolated drills for each theorem.
• Number System: Remainder theorem, cyclicity, and Euler’s theorem are the most testable concepts. These frequently appear as TITA questions — there is no negative marking, so always attempt them even if you are partially unsure.
• Modern Math: Dedicate limited time here. One focused week on PnC and Probability is sufficient — the expected return of 1–2 questions does not justify over-preparation.

Attempt strategy: In the 40-minute QA window, aim to attempt 14–16 questions with 80%+ accuracy. Identify easy-medium Arithmetic and Algebra questions first, then move to Geometry and Number System. Leave high-difficulty Algebra (Functions and Inequalities) for the end and use TITA questions as no-risk attempts.
