CAT 2021 Exam Pattern: Structure, Cutoffs & Lessons for CAT 2026
Why study a paper from four years ago? Because the CAT 2021 exam pattern locked in the 24-20-22 question split, the 40-minute sectional structure, and the TITA-to-MCQ ratio every CAT paper since has used. Conducted by IIM Ahmedabad during a pandemic-era recalibration, the CAT 2021 structure was deliberate, tested across three slots, and preserved almost entirely by IIM Lucknow (2022), IIM Kozhikode (2023), IIM Ahmedabad again (2024), and IIM Kozhikode (2025). For anyone preparing for CAT 2026, this CAT 2021 analysis is more useful than the most recent CAT 2025 paper, because it is the reference template against which every subsequent CAT exam pattern has been a minor variation.
CAT 2021 Exam Pattern: Fast Facts Dashboard
Before the section-by-section breakdown, the numbers that define the CAT 2021 exam pattern in a single dashboard. These nine data points are the baseline every CAT 2021 analysis builds on, and they are the exact numbers you should commit to memory before running any mock paper.
CAT 2021 at a Glance
Two shifts from pre-2020 patterns are worth noting. First, the 180-minute exam was cut to 120 minutes starting 2020 and kept at 120 minutes in 2021. Second, the sectional time was locked at 40 minutes — a permanent change that replaced the earlier 60-minute-per-section format that existed in CAT 2019 and before.
The marking system in the CAT 2021 structure is also worth internalising up front. MCQ questions carried +3 for correct, -1 for wrong. TITA questions carried +3 for correct and zero penalty for wrong. Roughly 19 of the 66 questions were TITA format, which quietly changed optimal attempt strategy: TITA questions became "safe attempts" because a wrong answer cost nothing. Aspirants who understood this asymmetry attempted 2-4 more questions per section than aspirants who treated every question as high-risk. The 45-attempt 99-percentile blueprint uses this exact marking logic to build a minimum-attempt, maximum-accuracy plan.
CAT 2021 Exam Pattern: Section-by-Section Structure
The CAT 2021 exam pattern preserved the three-section split but rebalanced the question counts within each section. Here is the exact CAT 2021 structure aspirants faced on exam day, section by section.
Four reading comprehension passages of four questions each (16 RC total), plus 8 Verbal Ability questions split across Para Summary, Para Jumbles, and Odd-Sentence-Out. Most VA questions were TITA format. Passages leaned into dense argumentative prose, a pattern every CAT since has continued and intensified.
Four sets of five questions each. Set complexity was polarised — two solvable sets, one hard set, one trap set — which set the precedent that later CAT DILR sections have followed. Set selection discipline mattered more than raw speed, a lesson expanded in the DILR set selection framework.
Arithmetic dominated (7-9 questions), followed by Algebra (5-7), Geometry (3-4), and Modern Maths (3-4). An onscreen calculator was available. TITA heavy weighting (roughly 36 percent) made the section more accuracy-rewarding than pre-2020 papers. Topic distribution is covered in depth in the CAT Quant syllabus guide.
CAT 2021 Difficulty Analysis by Section
Aggregate difficulty of CAT 2021 was moderate, but section-wise distribution was uneven. Based on post-exam CAT 2021 analysis from TIME, IMS, Career Launcher, and 2IIM, VARC was considered the hardest of the three sections by most aspirants, driven by dense passage prose rather than trick questions. DILR sat in the middle — two sets were approachable, two were deliberately punishing. QA was the easiest section in 2021 by coaching consensus, primarily because arithmetic questions dominated and the TITA ratio reduced negative marking risk.
This inverse-expectation pattern is itself a CAT 2021 exam pattern feature worth understanding. CAT historically skews aspirant expectations — the section that "should" be easy based on prior years often turns out to be the hardest. In 2021, many aspirants had built their prep around VARC being the friendly section and arrived unprepared for argument-dense passages.
Slot-wise difficulty did vary enough to matter. Slot 1 was considered marginally easier than Slots 2 and 3, but IIM Ahmedabad's normalisation process adjusted scaled scores to equalise percentile outcomes. Raw-score differences of 4-6 marks between slots translated to similar percentile bands after normalisation.
One concrete takeaway from the CAT 2021 analysis: allocate your mental preparation budget for VARC in proportion to its actual difficulty, not its historical reputation. Aspirants who walked into CAT 2021 treating VARC as a warm-up section consistently under-performed there by 6-10 marks. The same risk exists for CAT 2026 because passage density has continued rising since 2021. Read the VARC reading routine for the exact daily habit 99+ percentilers use to build the passage stamina the CAT 2021 pattern silently demanded.
CAT 2021 Cutoff Data: Raw Marks to Percentile
The most practically useful data from any CAT paper is the marks-to-percentile mapping. Based on post-exam CAT 2021 scorecard analyses published by TIME, IMS, 2IIM, and Career Launcher, these are the approximate CAT 2021 cutoff ranges across key percentile bands. Use them as anchor targets when you take CAT 2021 as a mock, and again when you set sectional score goals for CAT 2026.
Sectional 99 percentile cutoffs were roughly: VARC 40-45 raw marks, DILR 24-28 raw marks, QA 37-42 raw marks. DILR had the lowest raw-mark bar because the section was structurally harder — solving two full sets with high accuracy was often enough for a 99 sectional.
For reference, IIM shortlisting typically requires 85+ sectional percentile in all three sections plus a competitive overall percentile. CAT 2021 data suggests that aspirants who attempted 45 questions with 85 percent accuracy — a pattern covered in the 45-attempt blueprint — consistently cleared 99 percentile overall.
One calibration note on the CAT 2021 cutoff table. The raw-mark ranges shown above are approximate because IIM Ahmedabad publishes only percentile scorecards, not slot-wise raw-mark distributions. Coaching institutes reconstruct these numbers from student-reported scorecards plus their own slot-wise mock data. TIME's aggregated 2021 data, 2IIM's percentile calculator, and IMS's post-exam analysis agree to within 3-4 raw marks at each percentile band, which is well inside normal mock-variance. Treat these ranges as directional targets rather than exact thresholds.
How CAT 2021 Shaped Papers 2022-2025
The most overlooked fact about the CAT 2021 exam pattern is how rarely it was changed. Each conducting IIM from 2022 to 2025 retained the core template almost identically. Here is what persisted and what evolved:
| Element | CAT 2021 | CAT 2022-2025 |
|---|---|---|
| Total questions | 66 | 66 (every year) |
| Section split | 24-20-22 | 24-20-22 (stable) |
| Sectional time | 40 min each | 40 min each (stable) |
| MCQ + TITA mix | ~70% MCQ, ~30% TITA | Same ratio held |
| Negative marking | -1 MCQ, 0 TITA | Unchanged |
| VARC passage density | Moderate-dense | Increased each year |
| DILR set complexity | Polarised (easy-hard mix) | Polarisation intensified |
| QA topic weightage | Arithmetic ~35% | Arithmetic ~36% (stable) |
The structural skeleton is untouched. The flesh on the skeleton — passage density in VARC, set trickiness in DILR — has evolved incrementally. This is why CAT 2021 exam pattern analysis remains more valuable than people assume: it is the baseline from which every subsequent paper has been a minor variation, not a reinvention.
For aspirants who still think a four-year-old paper is too old to matter, flip the logic. If the CAT exam pattern is effectively frozen for five consecutive years, then the oldest paper in the frozen window is the most mature reference, not the least relevant. It has been battle-tested against four subsequent conducting IIMs without breaking, which is stronger validation than any single recent paper can offer. That structural continuity is the single most important fact in the CAT 2021 exam pattern story for CAT 2026 candidates.
Lessons for Today's CAT Aspirants
A historical paper analysis is only useful if it changes what you do next week. Three concrete lessons from the 2021 paper apply directly to CAT 2026 preparation:
- Do not over-prepare for pattern changes. Aspirants spend disproportionate energy tracking potential 2026 structural shifts. IIMs have shown five years of stability — the paper will almost certainly be 66 questions in 24-20-22 split. Plan for continuity, not disruption.
- Use CAT 2021 as a diagnostic mock. The full CAT 2021 paper is publicly available through standard coaching archives. It is the cleanest baseline diagnostic you can take — less stale than 2019, more representative than a custom mock. A 2021-era topper score today predicts your 2026 performance accurately.
- Train for the density, not the format. The exam pattern is stable. What changes year on year is the cognitive difficulty per question — denser VARC passages, trickier DILR sets. Your prep should focus on building the cognitive stamina the 2021 paper assumed, not on new formats.
- Cutoff targets anchor to the 2021 baseline. 99 percentile still sits near 75-85 raw marks. 99.5 sits near 90-100. Use these as working targets when setting your mock goals. See the CAT 2026 trend analysis for updated normalisation context.
CAT 2021 vs CAT 2026: What Changed
For aspirants wondering how the 2021 paper compares to the exam they will face in November 2026, here is the honest then-vs-now summary. Most differences are qualitative (within-section difficulty), not structural.
The Reference Paper
- 66 Qs, 120 min, 24-20-22 split
- VARC: argumentative passages introduced
- DILR: polarised set difficulty began
- QA: arithmetic dominance established
- 99 percentile: ~75-80 raw marks
- Normalisation across 3 slots
Evolution, Not Revolution
- Expected same 66 Qs, 24-20-22 split
- VARC: passages denser, more inference
- DILR: data-dashboard sets rising
- QA: functions/inequalities growing
- 99 percentile: still ~75-82 raw marks
- Normalisation process unchanged
The takeaway from the comparison: preparation plans built on the 2021 baseline remain structurally valid. The adjustments you make for CAT 2026 are mostly about what you practice inside each section, not how you allocate time across sections. The IIM CAT syllabus breakdown shows how priority topics have drifted since 2021.
Why CAT 2021 Still Matters
- The CAT 2021 exam pattern is the reference template for every CAT paper since — 66 questions, 120 minutes, 24-20-22 section split, 40 min sectional time, onscreen calculator available throughout.
- IIM Ahmedabad conducted CAT 2021 on 28 November 2021 across three slots. 1.92 lakh candidates appeared from 2.3 lakh registered; slot-wise normalisation equalised percentile outcomes despite 4-6 mark raw-score differences.
- CAT 2021 cutoff baseline from post-exam TIME, IMS, and 2IIM analyses still holds: 99 percentile at ~75-80 raw marks, 99.5 at ~90-95, 99.9 at ~105-115, 100 percentile at 130+ raw marks. Use as 2026 working targets.
- VARC was hardest, QA was easiest, DILR sat in the middle with polarised set difficulty (two solvable, two punishing). This CAT 2021 analysis pattern has held through CAT 2022, 2023, 2024, and 2025.
- Structural stability across four conducting IIMs: every element of the 2021 paper has been preserved in 2022-2025. Plan for continuity, not format change.
- Qualitative evolution: passage density in VARC rising, DILR sets getting trickier with data-dashboard formats, QA leaning more into functions and inequalities. Surface-level drift, not structural reinvention.
- Take CAT 2021 as a full diagnostic mock under real conditions, starting at the original 8:30 AM or 12:30 PM slot time. It is the cleanest baseline measurement available and the single highest-signal mock on your calendar.

Apply CAT 2021 Lessons to Your PrepFrequently Asked Questions
What was the CAT 2021 exam pattern?
The CAT 2021 exam pattern had 66 questions across three sections with a total duration of 120 minutes. The section split was VARC 24 questions (40 minutes), DILR 20 questions (40 minutes), and Quantitative Aptitude 22 questions (40 minutes). The paper had a mix of MCQ and TITA (Type In The Answer) questions with +3 for correct, -1 for wrong MCQ, and no negative marking on TITA. This 24-20-22 CAT 2021 structure became the standard template for every CAT paper from 2022 to 2025.
Who conducted CAT 2021 and when?
CAT 2021 was conducted by IIM Ahmedabad on 28 November 2021 across three slots. Approximately 2.3 lakh candidates registered and 1.92 lakh actually appeared for the exam. The paper was designed during the ongoing COVID-19 transition period and introduced the tighter 40-minute sectional structure that replaced the earlier 60-minute format used before 2020.
What was the CAT 2021 cutoff for 99 percentile?
Based on post-exam CAT 2021 analysis published by TIME, IMS, and 2IIM, the 99 percentile overall CAT 2021 cutoff was approximately 75-80 raw marks across the three slots. Sectional 99 percentile cutoffs were roughly VARC 40-45 raw marks, DILR 24-28 raw marks, and QA 37-42 raw marks. The 99.5 percentile cutoff sat near 90-95 raw marks, and the 99.9 percentile required roughly 105-115 raw marks. Exact numbers varied by slot due to IIM Ahmedabad's normalisation.
How does the CAT 2021 exam pattern compare to CAT 2026?
The CAT 2026 exam pattern is expected to mirror the CAT 2021 structure almost exactly: 66 questions, 120 minutes, and the same 24-20-22 section split with 40 minutes per section. The MCQ-TITA mix, negative marking, and onscreen calculator rules are unchanged. What has evolved is the density inside each section — VARC passages are more inference-heavy, DILR sets lean into data-dashboard formats, and QA leans further into functions and inequalities. Structurally, CAT 2021 remains the reference paper.
Why is CAT 2021 still relevant for CAT 2026 preparation?
CAT 2021 is still relevant because every CAT paper from 2022 to 2025 has preserved its structure with minimal change. Using CAT 2021 as a diagnostic mock gives aspirants the cleanest baseline pattern-recognition available. The 2021 cutoff map (99 percentile at ~75-80 raw marks) continues to anchor realistic 2026 score targets. Skipping CAT 2021 in favour of only recent mocks means losing the foundational signal on which every later paper was built.
What is the difference between MCQ and TITA in the CAT 2021 paper?
In the CAT 2021 paper, MCQ questions carried +3 for a correct answer and -1 for a wrong answer, while TITA (Type In The Answer) questions carried +3 for correct answers with zero negative marking for wrong ones. CAT 2021 had roughly 70 percent MCQs and 30 percent TITA questions. VARC had about 5 TITA, DILR about 6 TITA, and QA about 8 TITA. TITA format reduces guess risk and rewards accuracy, a dynamic that still shapes optimal CAT strategy in 2026.
