How Many DILR Sets to Attempt? Let Accuracy Decide
How many DILR sets should you attempt? Search that question and you will find tables. Aim for ninety percentile, attempt three sets. Aim for ninety nine, attempt five. The numbers look precise, they sit in a neat table, and they are effectively made up.
No official CAT source publishes an attempt count to percentile mapping, because no such fixed relationship exists. Set difficulty swings wildly year to year and person to person, and accuracy moves your score far more than raw attempt count ever does. Building a CAT preparation strategy around a borrowed number is how a plausible looking table turns into a genuine scoring mistake. The real answer is not a bigger number of sets. It is knowing which lever you actually control.
Before picking a target attempt count, check where your own accuracy actually stands. Work through a set of CAT DILR practice questions and track your accuracy on attempted sets, not just how many you finish.
- No verified source maps a specific attempt count to a specific percentile, because set difficulty and personal accuracy vary too much for a fixed table to hold.
- DILR score is a function of set selection and accuracy, not primarily raw attempt count, because wrong MCQ answers carry negative marking while TITA answers do not.
- If your current mock accuracy on attempted DILR sets sits below roughly sixty to sixty five percent, the priority is fewer, better chosen sets, not more attempts.
- Most aspirants who score well end up attempting a modest range of sets out of what is offered, not most or all of them.
- Set selection skill and your own accuracy rate are both things you can observe and improve. A fixed attempt target is not.
Why "How Many DILR Sets Should I Attempt" Has No Universal Answer
CAT DILR usually presents five sets in a section, and no two years carry the same difficulty spread across those five. A set that is genuinely solvable in eight minutes one year might be replaced by something closer to twelve the next, and the difference is rarely visible until you are three questions into it.
A fixed attempt count assumes every test taker faces the same five sets at the same difficulty and solves them at the same accuracy. Neither assumption holds. Two aspirants attempting the same three sets can land ten percentile points apart purely on accuracy, and the same aspirant attempting three sets one mock and five the next can score worse on the higher attempt count if accuracy dropped to compensate.
What actually drives your DILR score is negative marking asymmetry, and it is worth being precise about the mechanism instead of the folklore built on top of it.
Mentors reviewing DILR score sheets rarely see attempt count explain a score gap between two aspirants. They see accuracy explain it almost every time. The aspirant who attempted fewer sets but got nearly all of them right consistently outscores the one who attempted more and got half of them wrong.
The Accuracy First Attempt Model: 3 Tiers Based on Your Own Accuracy
Instead of a fixed attempt count, use your own mock accuracy on attempted DILR sets as the input. It is a number you can actually observe after every mock, unlike a percentile target you cannot control directly.
Tier 1: Below Roughly 60 to 65 Percent Accuracy, Fewer Better Chosen Sets
If less than two out of every three questions you attempt in DILR are correct, more attempts will cost you more than they earn. Cut your attempt count to the two or three sets you can identify as genuinely solvable in the first ninety seconds, and spend the saved time reviewing why the wrong answers went wrong.
Tier 2: Roughly 65 to 80 Percent Accuracy, Expand Attempts Cautiously
Your set selection is mostly working. Add one additional set per mock only after your accuracy on the current attempt count has held steady for at least two consecutive mocks, not after a single good one.
Tier 3: Above Roughly 80 Percent Accuracy, Attempt Count Is No Longer the Limit
At this accuracy level, the ceiling on your score is usually speed and set selection under time pressure, not whether you attempt one more set. Spend additional time on faster identification of a fifth solvable set rather than forcing an attempt on a set you have not confirmed is workable.
| Accuracy on Attempted DILR Sets | What It Is Telling You | Where to Focus Next |
|---|---|---|
| Below roughly 60 to 65 percent | Set selection or execution is breaking down on sets you should not have attempted | Cut attempts, review every wrong answer for the specific reasoning error |
| Roughly 65 to 80 percent | Set selection is mostly working, execution is close to reliable | Add one set per mock only after two stable mocks in a row |
| Above roughly 80 percent | Accuracy is no longer the limiting factor on your score | Work on faster set identification, not a higher attempt target |
The Arithmetic That Makes Raw Attempt Count Misleading
This is a generic illustration, not anyone's actual CAT score, but the arithmetic behind it is exactly why attempt count alone is the wrong target. DILR MCQs lose one mark for a wrong answer. TITA questions score zero for a wrong answer and carry no penalty.
Picture two hypothetical aspirants attempting the same DILR section. One attempts a large share of the available sets at fifty percent accuracy on MCQ heavy sets. The marks lost to wrong answers can equal or exceed the marks gained from the extra correct ones, leaving a raw score barely ahead of, or even behind, someone who attempted fewer sets at a much higher accuracy. The same principle holds across every section of CAT, not only DILR, wherever MCQ negative marking applies.
The number worth tracking mock to mock is not attempts. It is marks gained per attempt, net of marks lost to wrong answers on the same attempted set.
Chasing a specific attempt number because it appeared in a table somewhere, without checking whether your own accuracy at that attempt count actually supports it. An attempt count that worked for someone else's accuracy profile can quietly cost you marks on yours.
What a Realistic Attempt Range Actually Looks Like
Without pinning an exact number to an exact percentile, it is fair to describe the general shape of what strong scorers tend to do. Most aspirants who score well on DILR end up attempting a modest range of sets out of what is offered, not most or all of them, and the range tends to widen only as their accuracy and set selection speed both improve together.
That range is not a target to copy directly. It is closer to a natural consequence of high accuracy and fast set selection, which means chasing the number without the accuracy behind it usually backfires. Build the accuracy and the selection skill first, and the attempt count tends to move on its own.
Build the Accuracy a Higher Attempt Count Needs
Chasing a bigger number without the accuracy behind it usually costs marks, not gains them. Practice DILR sets by chapter and track your accuracy before you raise your attempt target.
Practice CAT DILR QuestionsSet Selection Skill: The Other Half of the Equation
Accuracy and attempt count get most of the attention, but set selection is what determines whether your attempts even had a fair chance of being correct. A well solved wrong set choice still costs you the same as a badly solved one.
Set selection means recognizing, within the first minute, whether a set is genuinely solvable in the time you have left, partially solvable for a subset of its questions, or a trap that will eat ten minutes for two or three answers. Our guide on which CAT DILR sets are worth skipping covers the specific signals that separate those three categories before you commit time to a set.
It is also worth knowing when to walk away from a set you already started. Our piece on what to do when your DILR sets stop moving covers the decision to abandon a stalled set rather than sunk cost your way through it.
How to Find Your Own Accuracy Threshold
Your accuracy threshold is not a one time number. It shifts as your set selection improves, so it needs checking every few mocks rather than assumed once and left alone.
- After each mock, note attempted questions and correct answers for DILR only, separate from your overall score.
- Calculate accuracy as correct divided by attempted, not correct divided by total questions in the section.
- Compare that number against the three tiers above and match your current attempt count to it honestly.
- If accuracy dropped from the previous mock at the same attempt count, treat that as the signal to pull attempts back, not to push through.
- Recheck the number every three to four mocks, since set selection speed improving is what eventually earns you a wider attempt range.
When to Trust the Instinct to Attempt One More Set
The instinct to attempt one more set usually shows up with ten or fifteen minutes left in the section, when a set on the page looks partially readable. Whether to trust that instinct depends on the same accuracy number, not on how much time is left.
- Has your accuracy at your current attempt count held steady for at least two mocks?
- Can you identify, within ninety seconds, whether this specific set is genuinely solvable?
- Would attempting this set replace a weaker set you have already started, or simply add to your total?
- If this set goes wrong, does the marks lost still leave you ahead of not attempting it at all?
A yes on the first two questions is a reasonable case for the extra attempt. A no on either one is a reasonable case for stopping where you are, since one more attempt is a bet on accuracy you have not yet confirmed you have. For a broader read on where DILR fits inside a full mock, our guide on when more CAT practice stops helping covers the same accuracy over volume principle from a full mock perspective rather than one section.
Track your DILR accuracy and set selection speed over time using a real plan instead of a guess. Our CAT DILR notation and shortcut sheets pair well with a mock by mock accuracy log while you calibrate your own threshold.
Run the Accuracy First Attempt Model on your next three mocks before you touch your attempt count again. Log your tier, check whether it moved, and let that number, not a table you found online, decide what next mock's target looks like.
Write your DILR accuracy on attempted sets at the top of every mock analysis, before you look at the overall percentile. The percentile reacts to a dozen things you do not control on a given day. Your own accuracy number is the one you actually influence between mocks.

Get My Strategy ReviewedFrequently Asked Questions About CAT Preparation Strategy and DILR Attempts
Is there a fixed number of DILR sets to attempt for 99 percentile?
No. No official or reliable source publishes a verified attempt count to percentile mapping, because set difficulty and personal accuracy vary too much from year to year and person to person for a fixed number to hold. Your accuracy on attempted sets is a far more reliable input than a target attempt count.
Should I attempt more DILR sets if my percentile is not improving?
Only if your accuracy on your current attempt count has already been stable for a few mocks. If accuracy is below roughly sixty to sixty five percent, adding attempts usually costs more marks through negative marking than it earns through extra correct answers.
Does TITA negative marking work the same as MCQ negative marking in DILR?
No. TITA questions score zero for a wrong answer with no penalty, while MCQ questions lose one mark for a wrong answer. A DILR set with more TITA questions is generally safer to attempt at lower confidence than one that is mostly MCQ.
How do I know if my DILR accuracy is good enough to attempt more sets?
Track correct answers divided by attempted questions, specifically for DILR, across your last three to four mocks. If that number sits above roughly eighty percent and has held steady, you have room to test one additional set. Below that, focus on set selection and accuracy before adding attempts.
