CAT 2026 Preparation: 80/20 Strategy Reveals the Most Important Topics Based on CAT 2025 Analysis

What does CAT 2025's Actual Question Distribution Show?

CAT 2025 went with the same old 68-question-based exam pattern, where there were 24 VARC, 22 DILR and 22 QA. Overall, the difficulty did change a bit across the slots, but the topic distribution remained consistent in a similar way every time.

CAT 2025 Proves Which Topics Matter Most

The biggest takeaway: Reading Comprehension remained the backbone of VARC, and Arithmetic, along with Algebra, together brought in around 12-14 of the 22 Quant questions (~44%) across all CAT 2025 slots.

Based on the Careers360 CAT 2025 analysis, here is how the Quant topics were distributed section-wise across all three slots.

There is always an appearance of Arithmetic in each CAT after 2021, while Geometry varies from 1-3 questions. Hence, Arithmetic should be learned first to optimise the expected value.

The 80/20 CAT Syllabus You Should Finish First

Quantitative Aptitude (QA)

If CAT 2025 had one clear message, it was that Arithmetic and Algebra continue to dominate Quant.

In Slot 2 alone, around 6–7 questions each came from Arithmetic and Algebra. Slot 3 was again Arithmetic-heavy with questions from Percentages, Profit & Loss, Time & Work, Time-Speed-Distance and Geometry, while Slot 1 featured multiple questions from Linear Equations, Profit & Loss, Mixtures and Coordinate Geometry.

Prioritise these topics first:

• Percentages

• Ratio & Proportion

• Profit & Loss

• Time & Work

• Time, Speed & Distance

• Simple Interest & Compound Interest

• Mixture & Alligation

• Linear Equations

• Quadratic Equations

• Inequalities

• Logarithms

• Functions

Geometry, Number System and Modern Mathematics should not be ignored, but they contributed comparatively fewer questions in CAT 2025.

CAT 2025 VARC: High-Weightage Topics

Verbal Ability & Reading Comprehension (VARC)

No section demonstrates the 80/20 principle better than VARC.

Across CAT 2025, Reading Comprehension accounted for 66.7% of the VARC section, while 33.3% contributed to Verbal Ability. The RC passages touched diverse themes AI and literature, plus economics and science, but the overall structure remained basically the same across the slots.

For most aspirants, improving RC accuracy will have a much greater impact than spending weeks on low-frequency verbal topics.

CAT 2025 DILR: High-Weightage Set Types

DILR is set-based, so it is better to analyse recurring set types instead of topics.

Data Interpretation & Logical Reasoning (DILR)

DILR feels a bit less tied to individual chapters and more to choosing the right set, you have to read the room or something. CAT 2025 kept moving with five sets and 22 questions total, covering graphs, arrangements, puzzles, caselets, and reasoning-based DI.

Where Should You Spend Most of Your Preparation Time?

If you’re starting your CAT 2026 preparation today, here’s the order you should follow for priority, a rough, must-do first list.

1. Reading Comprehension - this is 66.7% of VARC, so focus here early.

2. Arithmetic - the most repeated QA area, over and over.

3. Algebra - with Arithmetic, it adds up to more than half of QA, so don’t treat it lightly.

4. DILR set practice - it helps you get better at choosing the right set and also improves your pace.

5. Geometry basics - you’ll see it regularly, but the weight is usually a bit lower.

6. Number System and Modern Math - keep this for after you’ve mostly mastered the stuff above.

And no, this doesn’t mean you should skip the rest of the syllabus, just that you approach it in this order.

It simply ensures that your preparation is aligned with the areas CAT has tested most consistently in recent years.

CAT Topics You Can Prioritise Later

If your preparation time is limited, don't ignore these topics-but don't start with them either.

• Geometry

• Number System

• Modern Mathematics

• Low-frequency Verbal Ability question types

Recent CAT papers show these areas contribute fewer questions than the four priorities above. Once you've built strong accuracy in Reading Comprehension, Arithmetic, Algebra and DILR set selection, you can expand your preparation to cover the remaining syllabus.
