How to score well in the CAT DILR section? - The Data Interpretation & Logical Reasoning (DILR) section is considered to be the most ambiguous and intimidating section of the CAT. It does not have a defined syllabus like the other two sections. However, the challenge arises due to the aspirants’ unfamiliarity with topics that are not taught in school or college. This leads to most aspirants claiming that it is the most difficult section among the three, and thus it is extremely essential to have a proper CAT DILR preparation plan.
But the truth is that because most aspirants avoid this section and are not well-prepared, achieving a good percentile is easier due to low sectional performance. This raises the question - “How to improve CAT Data Interpretation & Logical Reasoning?” As you read along, you will find that preparation for DILR is based on practice. As you solve more and more questions, you will discover new techniques for solving particular questions. While the section has a syllabus that is not limited, regular preparation will familiarize you with the essential CAT DILR preparation tips required to reach the answer.
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 carried 32 questions split across 8 Sets. In the past years, the pattern has changed slightly. The CAT 2024 exam had 22 questions in the DILR section out of a total of 66 questions. This year, the sets were split equally, with 4-5 questions per set. While it is impossible to solve all 4-5 sets, a candidate can begin solving the sets from easy to difficult levels so that they can score well based on the easier questions.

The best method to ace the CAT Data Interpretation (DI) questions is to understand the basics of Maths and have a good knack for calculation. However, just having a strong command over calculations is far from enough. You need to practice solving DILR sets within a specific time limit. With regular practice, you will see how much you have improved your pace and your accuracy rate.
Before moving on to the right strategy to improve DILR, you must know that there is no 'one' right approach or strategy to improve DILR. Every student has a different strategy of their own. However, here we will talk about the most popular strategy. It revolves around two things -
This implies that the candidate must decide the level of difficulty of each set as per their own capability and finally move on to answer, "What sets am I going to answer and in what order (from easy to hard)?"
This whole task shouldn't take more than 5 minutes. 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, one must keep in mind to solve one set, including all the questions, in 13-14 minutes max. This
is more than sufficient time to solve all the sets chosen.
One should know exactly where they stand and what areas they are struggling with. The best way to find out these areas is through free DILR mock tests available online. When you know what your areas of weakness are, you can mould your preparation strategy accordingly, thereby improving your CAT DILR scores.
