How to score well in the CAT DILR section?
The Data Interpretation & Logical Reasoning (DILR) section is often considered the most ambiguous and intimidating part of especially for CAT 2026 aspirants. Unlike VARC or Quant, it has no fixed syllabus. The challenge mainly arises because many of the concepts tested in DILR are not taught in school or college, making the section feel unfamiliar and unpredictable.
As a result, a large number of candidates label DILR as the toughest section, which is why having a proper CAT DILR preparation strategy becomes essential. But the surprising truth is this: because most aspirants avoid this section or underprepare for it, scoring a high percentile is actually easier here compared to the other two sections.
This naturally raises the question-How do I improve my CAT DILR performance?
The answer lies in consistent practice. The more sets you solve, the faster you recognize patterns, shortcuts, and techniques. Even though DILR does not have a rigid syllabus, regular exposure to different puzzles and DI sets will gradually equip you with the essential CAT 2026 DILR preparation skills needed to score well.
The DILR section of CAT exam comprises problems according to the seat assignment, quantitative reasoning, puzzles, tables, graphs, and so on. The DILR section is split into two parts; Interpretation and Logical Reasoning. This section tends to be the most unpredictable section of CAT exam as it does not have any specific and defined syllabus as compared to the other sections. Due to this, students often find the DILR section challenging. Nevertheless, with a good strategy, students can achieve success in their preparation and in the examination as well.
So before we delve into details, let’s first understand what is Data Interpretation and Logical Reasoning:
Until CAT 2019, the DILR section had 32 questions across 8 sets. However, since CAT 2020, the exam pattern has been shorter. In CAT 2025, the DILR section included 22 questions, divided into 4-5 sets with 4-5 questions each.

The CAT DILR section today is far more logic-driven than calculation-heavy, so relying only on Maths basics or fast calculations is not enough. What truly improves performance is consistent practice with diverse DILR sets and learning how to solve them under time pressure. As you practice regularly, you'll notice steady improvement in your speed, accuracy, pattern recognition, and set selection skills- the real factors that determine your CAT DILR score.

This scanning process usually takes 2-3 minutes, not more. So, with an initial sacrifice of 5 minutes, a candidate has now strategized the next 35 minutes and the optimal course of action. Now apart from choosing the right number of sets, Ideally, aim to solve 1-2 sets depending on their difficulty; CAT DILR has become more about depth than quantity.

The DILR section for CAT has seen many changes over the years. Here is an overview of the past few years:
DILR for CAT is as crucial as VARC and QA, especially because IIMs release sectional cut-offs during the shortlisting process. The section is known for being challenging, time-consuming, and often responsible for lower scores. That's exactly why a structured strategy built around regular practice, timed sets, and smart analysis makes all the difference. Stay consistent, attempt diverse sets, and refine an approach that genuinely works for you. With the right plan, DILR becomes manageable and even scoring.
The ideal preparation strategy includes solving 2-3 sets daily, focusing on puzzle-based reasoning, practicing DI sets from previous CAT papers, and attempting weekly timed sectional tests. Building speed and accuracy through consistent practice is key.
Most high scorers aim to solve 2-3 high-quality sets with full accuracy. Since DILR is a high-difficulty and low-attempt section, smart selection of sets matters more than attempting all of them.
Important topics include Games & Tournaments, Arrangements, Venn Diagrams, Caselets, Missing Data, Graph-based DI, and Puzzle-based reasoning. Topics like simple blood relations or non-CAT style questions are rarely asked now.
DILR has been moderate to tough over the past few years. CAT 2024 introduced changes with more sets, while CAT 2022 and 2023 continued a puzzle-heavy pattern demanding strong logical filtering and data inference skills.
For most aspirants, 3-4 months of consistent practice is enough to build a strong base. However, improving accuracy and set-selection skills typically requires solving 50-70 diverse DILR sets over time.
