The important topics for CAT DILR 2026 aren’t really “topics” in the traditional sense; they’re set types. As per previous CAT exam trends, DILR includes arrangement-based sets, table/graph-based data sets, and trade or scheduling-based puzzles. If you know which formats to expect and how many questions they typically carry, you can walk into the section with a selection plan instead of guessing your way through five unfamiliar sets in 40 minutes.

How to Prepare for CAT DILR Section 2026
Here’s a strategy-first approach to DILR prep as per our CAT experts.
1. You Don’t Need to Attempt Everything
Here’s the number that surprises most aspirants: in CAT 2025, a scaled score of just 34 was enough for 99.5 percentile in DILR, roughly 11–12 correct questions. For 99 percentile, around 10 correct answers were sufficient. In CAT 2023, 99.5 percentile required just 28.5 marks.
In a 22-question section, that means solving 2-3 sets accurately and stepping back is a viable, even optimal, strategy. DILR rewards selection and accuracy far more than speed and volume, attempting a set you can’t crack wastes time and bleeds marks through negative scoring.
2. Know the PYQ Pattern, Not Just the Concepts
Certain set types, arrangement-based, table/graph-based, show up almost every year and contribute a predictable share of questions, while others are rare, high-difficulty outliers most students are better off skipping. Understanding this distribution tells you where to spend preparation time and sharpens your set-selection instinct on exam day.
3. Myths To Stay Away From in DILR Section
- “DILR is always difficult.” This isn’t quite true, DILR is fundamentally about structured thinking and pattern recognition, both of which are trainable with consistent practice.
- “I should attempt every set.” The instinct to try solving everything is natural, but in a negative-marking exam, that mindset quietly erodes your score rather than building it.
If DILR has been the section you keep hoping to “figure out eventually,” a structured set-selection framework, like the one covered in Career Launcher’s Race to 99%ile sessions, is built specifically to close that gap.
Conclusion
The important topics for CAT DILR 2026 come down to format recognition, not formula memorisation: arrangement-based and table/graph-based sets dominate every slot, and selection discipline, knowing which 2–3 sets to commit to, matters more than solving everything. Build that instinct through timed practice, not last-minute guessing.

Frequently Asked Questions
Q: Which DILR sets are most important for CAT 2026?
A: Arrangement-based sets (circular, linear, AR) and table/graph-based sets (bar, line, radar, point, step graphs) appeared in every CAT 2025 slot, making them the highest-priority formats to master.
Q: How many sets should I attempt in CAT DILR?
A: Based on CAT 2025 score-vs-percentile data, accurately solving 2–3 sets (out of 5) was enough for a 99%ile-range score in most slots. Selection and accuracy matter more than attempting all 5.
Q: What score is needed for 99 percentile in CAT DILR?
A: In CAT 2025, a scaled score of roughly 30 (about 10 correct answers) was sufficient for 99 percentile, and around 34 (11–12 correct) for 99.5 percentile.
Q: Should I attempt a set I don’t understand within the first minute?
A: No. DILR heavily rewards selection discipline. If a set isn’t clicking within the first minute or two of reading, it’s usually more efficient to move to the next set and return later, if time permits.
