CAT 2026 DILR Syllabus
The DILR section, or Data Interpretation and Logical Reasoning, of the CAT exam. It is the second section of the CAT exam (after VARC), and it is designed to test:
- Your problem-solving ability
- Logical thinking and reasoning
- Data handling and analysis
Each question is part of a set, and candidates need to solve 4–5 questions based on a single case or data set.

IIM CAT DILR Syllabus 2026: Important Topics & Weightage
There is no official CAT LRDI syllabus, but based on previous year CAT question papers, the section broadly covers:
CAT Data Interpretation Syllabus
CAT data interpretation section tests candidates’ knowledge of analysing and interpreting data presented in various forms, like tables, charts, and graphs. Topics covered under the Data Interpretation part of the CAT DILR syllabus include:
- Bar Graphs
- Line Charts
- Pie Charts
- Tables
- Mixed Graphs (combo of chart + table)
- Caselets (data in paragraph form)
- Data Sufficiency
- Venn Diagrams
- Percentage & Ratio-based analysis
Many of the questions in the CAT DILR section demand a solid comprehension of quantitative aptitude concepts, including percentages, averages, and ratios. These principles are frequently required for computations used to solve problems. Some of them are listed below:
- Growth/decline
- Comparisons across categories
- Averages/medians/totals
- Inferences based on conditions
CAT Logical Reasoning Syllabus
LR questions test your ability to understand logical connections, deduce conclusions, and analyse scenarios under constraints. Topics covered under the Logical Reasoning part of CAT LRDI syllabus include:
|
Topic |
Question Types |
| Arrangements |
Linear, Circular, Matrix, Complex |
|
Team Formation/Grouping |
Based on conditions and constraints |
| Puzzles |
Multi-variable, constraint-based |
|
Venn Diagrams |
Logical overlaps, data-based grouping |
| Games and Tournaments |
Points-based competitions |
Note: These topics are integrated in caselets. You won’t get direct standalone questions.

What Makes CAT DILR Challenging?
- No fixed topic list
- Lengthy caselets that require deep focus
- Unpredictable set difficulty—some are easy, others are highly complex
- Time management is crucial, as 1 difficult set can eat up 20+ minutes
That’s why the selection of the right sets is as important as solving them correctly.
How to Prepare for the CAT DILR Section?
- Understand Set Types: Begin by solving basic DI and LR sets to become familiar with the types of problems presented.
- Practice from Previous Year CAT DILR Papers: Solve at least 30–40 sets from the past 5 years to identify recurring patterns.
- Build a Set Selection Strategy: Learn to judge which sets are worth attempting and which to skip.
- Mix of MCQs & TITA: Practice both formats to improve speed and reduce dependency on options.
- Sectional Tests: Time-bound free CAT mock tests help simulate exam pressure and improve speed.

CAT DILR Preparation Tips 2026
- Start with easier sets and build momentum
- Avoid ego traps—if a set takes too long, move on
- Focus on accuracy over attempts
- Analyse each mock DILR section in detail
- Maintain a DILR journal to track the types and logic used
CAT DILR Syllabus Difficulty Level: Slot-Wise Variation
CAT is conducted in multiple slots, and DILR difficulty can vary across them. Sometimes Slot 1 may have 2 easy sets, while Slot 2 has none. The key is adaptability—practicing a mix of easy, moderate, and tough sets helps build that skill.

Frequently Asked Questions
Q: What is the CAT DILR syllabus 2026? A: The CAT DILR syllabus 2026 covers two areas — Data Interpretation and Logical Reasoning. DI includes bar graphs, pie charts, tables, caselets, and ratio-based analysis. LR includes arrangements, puzzles, team formation, Venn diagrams, and games & tournaments. There is no official syllabus released by IIMs — topics are based on previous year paper trends.
Q: How many questions are in the CAT DILR section 2026?
A: The CAT DILR section has 22 questions across 4 sets with a 40-minute time limit. Questions are a mix of MCQ and TITA format. MCQs carry +3 for correct and -1 for wrong answers. TITA questions have no negative marking.
Q: What is the difficulty level of CAT DILR?
A: CAT DILR difficulty ranges from moderate to high. It varies across exam slots — some slots may have 2 easy sets while others have none. The unpredictability of set types and lengthy caselets makes it one of the most challenging sections in CAT.
Q: How many sets should I attempt in CAT DILR to score well?
A: Aim to attempt 2–3 sets with high accuracy rather than trying all 4 sets. One difficult set can consume 20+ minutes. Selecting the right sets to attempt is as important as solving them correctly.
Q: What is the difference between DI and LR in CAT DILR?
A: Data Interpretation involves analysing data from charts, tables, graphs, and caselets. Logical Reasoning involves solving constraint-based problems like seating arrangements, team formations, and puzzles. In recent CAT papers, many sets are mixed — combining both DI and LR in a single caselet.
Q: Are calculators allowed in CAT DILR?
A: Yes, an on-screen calculator is available during the exam. However, candidates should avoid over-relying on it for basic calculations involving percentages, averages, and ratios to save time.
Q: I keep running out of time in DILR — what should I do?
A: This is the most common DILR challenge. Spend the first 2–3 minutes of the section scanning all sets before solving any. Pick sets that look structured and familiar. Skip sets with too many variables early on. Building a set selection habit through timed mock practice is the best fix.
Q: How should I start preparing for CAT DILR if I find it very confusing?
A: Start by solving basic DI sets — tables and bar graphs first, then move to caselets. For LR, begin with linear arrangements before moving to complex puzzles. Practice 30–40 sets from previous year CAT papers, maintain a DILR journal to track patterns, and take weekly timed sectional tests to build speed and confidence.
