Data Interpretation & Logical Reasoning (DILR) is considered the most challenging Section of the CAT Exam, the section consists of 20 questions based on mixed concepts of Logical Reasoning and Data interpretation. Students who are weak in this section often believe in certain myths about the CAT’s DILR Section. So before discussing the preparation strategy, we will bust some of the most common myths about DILR for CAT Exam.
Syllabus of DILR for CAT Examination:
DILR Syllabus for CAT 2024 consists of problems based on the seating arrangement, quantitative reasoning, puzzles, Venn diagrams, blood relations, graphs, tables, etc. The DILR syllabus is divided into two parts – Data Interpretation and Logical Reasoning.
Data Interpretation: Data will be presented in the form of a graph, chart, or another form of visualization and you will be required to solve the questions given based on the information given.
Logical Reasoning: Here you may be given information in a non-structured manner and you may be required to structure it and derive the outcome to solve the given Questions.
Although the Data Interpretation and Logical Reasoning section does not have a fixed syllabus, hence the best way to prepare for this section is to Practice different types of sets. It may take some time to get used to different question templates that CAT generally sticks with, but it is the best way to get better in this section. In this article, we are going to discuss how to crack the DILR for CAT.

Problems Faced in the DILR Section of the CAT Exam
Like every other section of the CAT Exam, you are provided 60 minutes to solve DILR for CAT. Completing all Here we have listed some of the most common problems aspirants face in this section.
- Not selecting the right DILR Set.
The paper setters of the CAT Exam have mastered the art of creating a good mix of easy and difficult questions. When you go through the past year’s CAT question papers, you will observe that there are always at least 2 doable sets that may take 15-20 minutes to solve. On the other hand, there will always be some sets that might be quite tough to crack and might take 30-40 minutes to solve. The reason for having such a mix of sets is to test the time management skills and selection capabilities of the candidates. As a good manager, you will want first to target the low-hanging fruits in the exam.
To perform well in the exam, you need to master the art of selecting the right set to attempt. You should first attempt the sets that you are familiar with. As in this section, accuracy is more important than the number of attempts. - Not being familiar with certain types of sets.
Most of the time, you will observe that you were not able to solve a set even after you knew the basic concept. This is an indicator of the fact that either you do not know the concept well or that you are not well versed in the concept application skills. Practice plays an important role in increasing familiarity with the standard variety of sets.
- Bad time management.
Bad time management is one of the most common mistakes that candidates make in the DILR Section of the CAT Exam. Sometimes, candidates end up wasting their entire time in solving a single set, without going through the other sets. Sometimes even after putting in time, you may not be able to solve the set correctly. Hence it is suggested to first skim through all sets of DILR Section. One’s time management skills can improve by taking full-length practice tests and mocks.
- Not reading questions carefully.
Not reading a question carefully might result in a loss of time during the exam. Like, suppose you read a case incorrectly in some DILR Set, due to which you invested 20 minutes to solve a question, that you could have solved in 10 minutes or maybe less than that.
As you know, time is a constraint in the CAT exam. And one do not want to lose out their precious time on silly mistakes. Moreover, one should pay good attention while solving questions involving complex calculations.

How to Prepare DILR For CAT
The CAT DILR section is considered to be the trickiest section in the CAT exam. Planning and executing the right strategy for DILR in the CAT Exam can help you with getting a 99%le in the CAT DILR section. The Data Interpretation and Logical Reasoning (DILR) section in CAT can be challenging, but with proper preparation and practice, you can crack it. Here are some tips:
- Practice regularly: The more you practice, the better you get. Try to solve a variety of DILR questions from previous year’s CAT papers and other sources.
- Focus on concepts: Make sure you have a good understanding of the basic concepts of DILR. This will help you solve complex problems easily.
- Develop problem-solving skills: DILR questions are designed to test your problem-solving skills. Try to develop a systematic approach to solve problems.
- Time management: Time management is crucial in CAT. Try to solve questions within the time limit to improve your speed and accuracy.
- Analyze your mistakes: After attempting a DILR section, analyze your mistakes and try to understand where you went wrong. This will help you avoid making the same mistakes in the future.
Where to Practice from?
One can improve DILR for CAT only through dedicated Practice. Initially, one may start with basic concept-building, which can be done from the lectures. After which one can start practising basic sets and can later move to more complex questions. The iConcept-material by iQuanta can serve as a good resource for DILR practice.
As the concept-building material can only help you to a certain level, hence iQuanta has come up with comprehensive CAT Preparation Books for the benefit of all CAT aspirants. Unlike the usual preparation materials, these books are Updated as per the recent trends of the exam.
