Tricks to Improve Speed and Accuracy in CAT 2026 DILR are not about solving every set as quickly as possible. The key is to identify the right sets, manage your time effectively, and solve the selected sets with minimum errors.
With limited time in the DILR section, spending too long on a difficult set can affect your overall score. A better approach is to recognise which sets are worth attempting, move on when a set is taking too long, and focus on maximising accuracy in the sets you choose.
This blog covers practical tricks to help you improve your speed, make better set-selection decisions, and maintain accuracy in CAT 2026 DILR.

Start with Set Selection: The First 2-3 Minutes Matter
Before attempting any questions in DILR, spend the first two to three minutes scanning all the sets. The objective is not to decide which set looks interesting, but to identify the sets that can be approached efficiently. While scanning a set, look for these four factors:
- Number of variables: Check how many entities, categories, or elements are involved. Sets with too many variables can require more time to organise and track the information.
- Nature of the constraints: Determine whether the conditions are clearly stated or require multiple inferences before you can begin solving.
- Interaction between constraints: A set can become time-consuming when several conditions interact with multiple variables. Assess how easily you can organise these conditions before committing to the set.
- Familiarity with the data format: Do not judge a set only by its topic or category. A set may appear unfamiliar but still have a straightforward structure that you can work with. Focus on whether you can identify a clear starting point.
Make a quick go/no-go decision based on whether you can structure the set and answer its questions without excessive inference. A few minutes spent on selection can save valuable time and improve accuracy.

Build the Grid to Improve Accuracy
A structured approach can make DILR sets easier to manage and reduce errors. Instead of trying to remember every condition while solving, create the framework first and then place the information into it.
For example, in the CAT 2022 Slot 3 set on CS and non-CS students across AI and ML, the information involved eight interlinked conditions based on grade ratios. The set can be organised into a table with:
- Columns: AI, ML and Total
- Rows: CS, Non-CS and Total
- Grades within each cell: A, B, C and F
The table is created before applying any of the given conditions. This gives you a clear structure in which to organise the information rather than trying to track multiple relationships mentally.
Keep the following points in mind while building the framework:
- Write down all the constraints first: Note the given conditions together before attempting the questions. This avoids repeatedly going back to the set to look for information and saves time.
- Start with the most-constrained entity: Identify the variable or entity linked to the maximum number of conditions. Starting here can help determine other parts of the arrangement with fewer assumptions and less trial and error.
- Check the completed framework: Before answering the questions, verify the arrangement against every given constraint. Since all questions depend on the same arrangement, missing one condition can affect the accuracy of the entire set.
Approximation: When to Use It in DILR
Approximation can save valuable time in DILR, but it should be used selectively. Keep these points in mind:
- Use approximation for trends and comparisons: In chart-based DI, estimation can be useful for comparing growth rates, identifying which segment has a larger share, or checking whether a value is close to a particular threshold. When the options are sufficiently far apart, an exact calculation may not be necessary.
- Avoid approximation when values are used again: If a calculated value will be used in another deduction, even a small approximation can affect the subsequent calculations and lead to an incorrect conclusion. This is particularly important in LR sets and DI sets where missing information has to be derived from other values.
- Look at what the question is asking: The CAT 2024 Slot 3 OTT subscribers set included questions where estimation could help, while a question asking for the minimum possible percentage required an exact boundary value and could not be solved through approximation.
- Check before rounding: Before approximating a value, ask whether it is the final answer or an input for another calculation. This can help you save time without compromising accuracy.
Why Games and Tournaments Matter in DILR
Avoiding an entire DILR set type can unnecessarily limit your options during the exam. Games and Tournaments are worth including in your preparation because they have appeared consistently in recent CAT papers.
- Do not skip the category altogether: Games and Tournaments sets appeared across the slots of CAT 2023, CAT 2024 and CAT 2025. Being comfortable with this format gives you more options during set selection.
- Practise different formats: Solve sets based on different sports and tournament structures, such as hockey, archery, javelin, rifle shooting and multi-round tournaments. This helps you become familiar with different ways of presenting conditions and results.
- Focus on recognising the set: The goal is not to solve every Games and Tournaments set quickly. Regular practice should help you assess a set within the initial scan and identify whether its structure is manageable.
- Make the decision based on the set, not its category: Do not reject a set simply because it is based on a tournament. Look at the number of conditions, how they interact, and whether you can identify a clear starting point before deciding whether to attempt it.
Set Time Limits to Manage DILR Effectively
Time management in DILR preparation requires you to know when to continue with a set and when to move on. Use two checkpoints while solving:
- Five-minute rule: If you have spent five minutes on a set but are still unable to establish the basic arrangement or make progress with the opening constraint, consider leaving the set. The idea is to avoid investing more time in a set that is not opening up.
- Ten-minute rule: If the arrangement is still incomplete after ten minutes, move to another set, even if you feel you are close to solving it. Continuing because you are “almost there” can turn a manageable time investment into 15–20 minutes on a single set.
These checkpoints help prevent one difficult set from consuming the time you need for other, more manageable sets.
Use Mock Analysis to Improve DILR
Re-solving a DILR set you got wrong is not enough. The real improvement comes from identifying why you went wrong, as the solution depends on the type of error.
- Selection error: You chose a difficult set while an easier one remained untouched. Revisit your 90-second scan and check whether you are identifying the right signals while selecting sets.
- Constraint error: You missed or misread a condition, causing errors in the arrangement later. Make it a habit to note down all the conditions before solving.
- Overtime error: You spent 10–12 minutes on one set and lost the opportunity to attempt another. Work on following your time cutoffs consistently, especially under exam pressure.
Do not stop your analysis at “I got this set wrong.” Identify the exact reason and work on that specific weakness.
To build stronger set-selection and time-management skills, practise at least full-length CAT Mock Test, timed DILR sections before the exam. This means completing entire 40-minute sections under timed conditions, rather than simply solving individual sets.

The Last Ten Days Before CAT 2026
The final ten days should be about maintaining your existing preparation rather than adding new approaches.
- Do not take up new set types: Stick to the formats and approaches you have already practised. Use this period to analyse your mocks and revise your mistakes instead of expanding your preparation.
- Practise scanning without solving: Read a DILR set, assess it, and decide whether you would attempt it. Stop there. These short drills help you retain the ability to judge sets quickly without exhausting your analytical energy.
- Prepare for the VARC-to-DILR transition: DILR comes immediately after VARC, so your mindset after the first section can affect how you approach the next one. In your final mocks, practise starting DILR even when VARC has not gone as expected. The aim is to stay composed and follow your DILR plan regardless of what happened in the previous section.

Conclusion
Improving speed and accuracy in CAT DILR comes down to making better decisions while solving. Selecting the right sets, building a clear framework, using approximation selectively, and following time limits can help you avoid unnecessary time loss and reduce errors.
The goal is not to solve every set in the section. It is to identify the sets you can solve efficiently, stay disciplined with your time, and maintain accuracy under exam pressure. With regular timed practice and proper mock analysis, you can make your DILR attempts more consistent before CAT 2026.
Frequently Asked Questions
1. How much time should I spend scanning DILR sets in CAT 2026?
A. Spend around two to three minutes scanning the sets before deciding which ones to attempt. Look at the structure, constraints, number of variables, and whether you can identify a clear starting point.
2. When should I leave a DILR set?
A. If you have spent around five minutes but have not been able to establish the basic arrangement or make meaningful progress, consider leaving the set. If the arrangement is still incomplete after ten minutes, move to another set even if you feel you are close to solving it.
3. Is approximation useful in CAT DILR?
A. Yes, but only when the question allows it. Approximation can help with trends, comparisons, and values where the answer options are sufficiently different. Avoid it when the calculated value will be used for further deductions or when an exact boundary value is required.
4. Should I skip Games and Tournaments sets in CAT DILR?
A. No. Games and Tournaments have appeared consistently in recent CAT papers, so avoiding the entire category can unnecessarily limit your options. Instead, assess the structure and constraints of the particular set before deciding whether to attempt it.
5. How can mock analysis improve DILR performance?
A. Analyse the reason behind each mistake instead of simply re-solving the set. Identify whether the problem was set selection, missing a constraint, or spending too much time on one set. This helps you work on the specific weakness that caused the error.
