Most CAT aspirants lose the exam in DILR, not in Quant. The CAT 2027 DILR syllabus has no official topic list, but the same set types return every year: tables, graphs, arrangements, games and networks. This guide gives you that complete topic list, the section pattern, the weightage trend and a simple plan to cover it.
Is There an Official CAT 2027 DILR Syllabus?
No. The IIMs publish the exam pattern on the official CAT website but do not release a topic-wise Data Interpretation and Logical Reasoning syllabus. The CAT 2027 notification is also not out yet. If the usual cycle holds, it should follow in mid-2027, and the exam should fall in late November 2027.
So the DILR syllabus for CAT 2027 below is built from recurring set types in recent CAT papers. Treat it as a reliable preparation guide, and check the official information bulletin once it is released.

CAT DILR Syllabus 2027: Complete Topic List
The CAT DILR syllabus has two parts. Data Interpretation tests how fast you read and compute from data. Logical Reasoning tests how well you organise conditions into a solvable structure.
Data Interpretation Topics
| Topic | What it covers | Priority |
|---|---|---|
| Tables and caselets | Rows, columns or paragraph data; percentages and ratios | High |
| Bar graphs and line charts | Single, grouped and stacked graphs; trends | High |
| Mixed or connected data | Two or more sources that must be linked | High |
| Pie charts | Percentage shares, often paired with a table | Medium |
| Missing data sets | Fill blanks using totals and conditions | Medium |
| Data change over time | Period-wise growth and indices | Medium |
Logical Reasoning Topics
| Topic | What it covers | Priority |
|---|---|---|
| Arrangements | Linear, circular and grid seating; ordering | High |
| Games and tournaments | Round robin, knockout, points tables | High |
| Venn diagrams and sets | Overlapping groups with numbers | Medium |
| Scheduling and sequencing | Time slots, tasks, dependencies | Medium |
| Routes and networks | Paths, connections, cost or distance | Medium |
| Binary logic and truth-lie | Yes/no grids, true/false statements | Medium |

CAT 2027 DILR Weightage: What to Expect
CAT does not publish topic-wise weightage, so any exact percentage you see online is an estimate. What recent papers do show is a pattern:
- DI and LR sets share the section roughly equally, but the exact mix changes every year.
- Arrangements, games and tournaments, tables and graphs appear most often.
- Difficulty is uneven. Usually one or two sets are approachable and the rest are time-consuming.
Because of this, set selection matters more than topic coverage. A strong DILR attempt usually comes from solving two or three sets fully, not from touching all five.
How to Prepare for the CAT 2027 DILR Syllabus
A 12-Week Plan
| Phase | Focus |
|---|---|
| Weeks 1 to 4 | Learn DI basics and core LR set types. Solve one set daily. |
| Weeks 5 to 8 | Move to mixed and harder sets. Practise picking the best two or three sets in the first 5 minutes. |
| Weeks 9 to 12 | Take timed sectionals and full mocks. Review every set, including skipped ones. |
Practical Tips
- Solve sets untimed first, then add the 40-minute limit.
- Keep an error log: wrong reading of data, calculation slips and skipped easy sets.
- Always attempt TITA questions, since they carry no negative marking.
- Build calculation speed with percentages, ratios and averages.
To practise, use CATMOCK’s DILR daily practice and the DILR Bhandara set bank. Then test your timing in CAT sectional mocks and full-length mocks. Solving CAT previous year papers shows you how real sets are built.
