DILR Sets to Attempt for 99 Percentile in CAT 2026
If you are targeting 99 percentile in DILR in CAT 2026, aim to solve 300+ quality DILR sets during your preparation. This should include CAT PYQs, sectional-test sets, mock-test sets and carefully selected practice sets covering a wide variety of DI and LR set types.
A good weekly target is 15–20 sets. At this pace, you get enough exposure to different patterns without turning preparation into a numbers game. More importantly, spend time analysing the sets you solve: identify where you lost time, whether your approach was efficient and whether you could have selected the set faster.
DILR Preparation Target | Recommended |
Total DILR sets | 300+ |
Sets per week | 15-20 |
Sets per day | 2-3 |
CAT PYQs | Essential |
Sectional Tests | Once or Twice Every Week |
Full Length Mock Tests | Atleast Once Per Week |
Main focus | Accuracy + selection + speed |
The 300-set target is not about solving 300 sets mechanically. The real benefit comes when every set improves your ability to read the data, identify the structure, make deductions and decide whether the set is worth attempting.

CAT DILR Score Required for 99 Percentile
There is no fixed DILR score that will correspond to 99 percentile every year. The required score changes depending on the difficulty of the section and the normalization across slots.
For CAT 2025, the DILR score corresponding to the 99 percentile was around 29.8 marks, while 95 percentile was around 21.5 marks. This makes 30+ marks a useful target during preparation. However, don't treat 30 marks as a permanent cutoff. A difficult DILR paper can produce a much lower score requirement for the same percentile.
DILR Percentile | CAT 2025 Score |
99.9 | 38 |
99.5 | 33 |
99 | 29.8 |
95 | 21.5 |
90 | 16.7 |
85 | 14 |
80 | 11.5 |
The practical goal should therefore be to make 30+ marks a regular score in your DILR sectionals and mocks, rather than trying to predict the exact score that CAT 2026 will require.

How Many DILR Questions Should You Attempt for 99 Percentile?
The number of questions you attempt is less important than the number you get right. In DILR, a candidate who selects the right sets and solves 10–12 questions accurately can outperform someone who attempts more questions with several errors.
For a 99 percentile target, 12–14 well-selected attempts can be a strong goal, provided your accuracy is high.
Correct Questions | Marks |
8 | 24 |
9 | 27 |
10 | 30 |
11 | 33 |
12 | 36 |
13 | 39 |
14 | 42 |
For example, 10 correct answers already give you 30 marks before accounting for incorrect attempts. So instead of thinking about attempting every possible question, focus on finding 10–12 questions that you can actually convert, basically 2-2.5 sets. This is why set selection becomes so important in DILR.

Is Solving 3 DILR Sets Enough for 99 Percentile?
Three sets can be enough, but there is no fixed rule that solving exactly three sets will give you 99 percentile. What matters is which three sets you choose and how many questions you get correct from them.
Recent CAT papers have used different combinations of set sizes. CAT 2025, for example, had five DILR sets and 22 questions in total, so the number of questions obtained from three sets could vary.
Suppose you identify 2-3 manageable sets containing 10-12 questions in total and solve most of them correctly. That can put you around the 30+ mark. On the other hand, spending 15 minutes on a complicated set and getting only two questions right is unlikely to be productive. So, don't make "three sets" your target. Make "maximum correct answers from the right sets" your target.

How to Select the Right DILR Sets in CAT
Set selection is one of the most important skills in DILR. The first few minutes of the section should be used to understand all the sets rather than immediately starting with the first one.
Look for sets where the information is structured clearly, the conditions are manageable and you can see a possible starting point. Familiarity with a particular type of set can help, but don't select a set simply because you have seen the topic before.
Prefer Sets With | Be Careful With |
Clear information | Too many conditions |
Manageable calculations | Lengthy calculations |
A clear starting point | No obvious starting point |
Limited cases | Multiple complicated cases |
Questions linked to one setup | Very lengthy individual questions |
Familiar logical structure | Unclear or highly complicated structure |
With enough practice, set selection becomes almost instinctive. This is one of the biggest reasons to solve 300+ sets: you gradually learn to recognise which sets are likely to consume time and which ones offer better opportunities.
A useful rule during the exam is simple: if you have spent several minutes without making meaningful progress, stop and reassess. Staying emotionally attached to one difficult set can cost you the opportunity to solve an easier one.

DILR Attempt Strategy for 99 Percentile
DILR is a 40-minute section, so your strategy should revolve around selection, execution and time control. A practical approach is to spend the opening few minutes scanning the sets and then work through them in priority order.
Time | What to Do |
0-3 minutes | Scan all DILR sets |
3-5 minutes | Decide the order of attempts |
5-17 minutes | Solve the first selected set |
17-29 minutes | Solve the second selected set |
29-40 minutes | Attempt independent questions or attempt another set |
These timings are not rigid. If you are making good progress, continue. If a set is taking too long without giving you useful deductions, move away and return later if required.
The ideal thought process is: Scan → Select → Solve → Verify → Move
Your 300+ practice sets should eventually make the first two steps much faster. You should be able to look at a new DILR set and quickly judge its structure, difficulty and potential.
Remember that speed in DILR does not simply mean solving faster. It also means knowing quickly which questions and sets not to solve.

DILR Sets To Attempt for 99 Percentile in CAT 2026: Conclusion
A 99 percentile DILR preparation plan should be built around 300+ quality sets and 15–20 sets every week. Include CAT PYQs throughout your preparation, along with sectional tests, mock-test sets and different types of DI and LR problems.
The objective is not to finish 300 sets for the sake of a number. Every set should help you improve at least one of three things: solving ability, set selection or time management.
For the actual CAT, keep 30+ marks as a useful DILR benchmark and work towards around 12-14 accurate attempts. CAT 2025 data shows that around 29.8 marks corresponded to the 99 percentile in DILR, but the required score can change significantly depending on the difficulty of the paper.
