CAT DILR Strategy: How to Solve Sets Faster

The fastest way to solve CAT DILR sets faster is to recognise that today's DILR paper blends two categories, calculation-heavy DI sets (pie charts, line graphs, tables, spider charts) and case-based LR+DI sets (including single arrangement puzzles), into combined caselets rather than keeping them separate. On top of that, a specific group of "new-age" set types, scheduling problems, routes and networks, and games and tournaments, has appeared in every single CAT slot over the last five years, which makes them the highest-leverage topics to train deliberately rather than leave to chance.

This CAT DILR topic-wise strategy, from a CATking DILR strategy session, recommends starting preparation with scheduling problems specifically, then working systematically through old CAT papers rather than random practice sets, using CATking's dashboard archive of past papers formatted in the real CAT interface.

The Two Categories of CAT DILR Sets

CAT DILR sets broadly split into two types of demand on the candidate. Number-crunching sets test calculation speed and accuracy. Case sets test logical deduction, often combined with data interpretation. In recent years, CAT's paper setters have increasingly blurred the line between the two, producing caselets that require both skills within a single set.

Why New-Age Problems Deserve Dedicated Practice

A lot of the anxiety around DILR comes from treating it as a section with no fixed syllabus. That's partly true for case sets and number-crunching sets, which can take almost any form. But scheduling problems, routes and networks, and games and tournaments behave differently: this CATking strategy session notes that going through the last five years of CAT papers shows at least one of these three types in every single slot, with some papers including all three. That consistency makes them worth specific, dedicated preparation rather than generic set-solving.

The recommended starting point is to pick up any DILR book, work through scheduling problems specifically first, and then move into a systematic run through old CAT papers rather than solving sets at random. CATking has uploaded old CAT papers on its dashboard formatted to match the real CAT interface, and has produced solved video walkthroughs of routes-and-networks problems spanning papers from 2015 to 2025, taught by mentors with IIM Lucknow and IIM Indore backgrounds.

Student Experience

Two CATking students, Sezal Sharma and Saurdeep Chaudhary, shared their experience with this DILR strategy approach, with one reporting a 99.20 percentile in CAT. Both credited the consistency of the video-based strategy sessions and the CATking dashboard's exam-like interface for reducing the unfamiliarity that usually comes with DILR on exam day.

Frequently Asked Questions

Q1. What are the two main categories of CAT DILR sets?

CAT DILR sets broadly fall into number-crunching sets (pie charts, line graphs, tables, spider charts) and case sets (a combination of logical reasoning and data interpretation, including single arrangement puzzles). In recent CAT papers, these two categories increasingly overlap in the form of combined caselets.

Q2. What are "new-age" problems in CAT DILR?

New-age DILR problems refer to scheduling problems, routes and networks, and games and tournaments. These are a distinct group from standard DI and LR sets and have shown up consistently across recent CAT papers.

Q3. How often do scheduling, routes and networks, and games and tournaments appear in CAT DILR?

Based on a review of the last five years of CAT papers referenced in this strategy, at least one of these three new-age problem types has appeared in every single slot, and some papers have featured all three together.

Q4. Where should I start practicing new-age DILR topics?

The recommended starting point is scheduling problems specifically, using any standard DILR practice book, before moving on to routes and networks and games and tournaments through topic-wise practice and old CAT papers.

Q5. Should I solve old CAT papers or a DILR practice book first?

This strategy recommends using a book to build a foundation on scheduling problems first, then moving into a systematic, topic-wise run through old CAT papers rather than solving sets randomly.

Q6. Are DI and LR still separate in CAT DILR, or do they overlap?

They increasingly overlap. While some sets are purely calculation-based (DI) or purely reasoning-based (LR), CAT's paper setters have been combining both into caselets, so many recent sets require both data interpretation and logical deduction at once.

Q7. Who can guide me through routes and networks or scheduling problems for CAT?

CATking has produced solved video walkthroughs of routes-and-networks problems from CAT papers spanning 2015 to 2025, taught by mentors with IIM Lucknow and IIM Indore backgrounds, alongside an archive of old papers on its dashboard formatted to match the real CAT interface.

Q8. How many old CAT DILR papers should I solve before the exam?

This strategy doesn't specify an exact number, but recommends a systematic, complete run through old CAT papers, organised by topic, rather than solving a handful of random sets. The focus should be on covering scheduling, routes and networks, and games and tournaments across multiple years rather than just attempting a few papers end to end.
