Most aspirants confuse raw score (the marks you actually scored) with percentile (your relative rank). They aren't the same. A raw score of 100 might be 95%ile in a tough year and 88%ile in an easy year. IIMs select on percentile, not raw score — which is why understanding this conversion is the difference between targeting a realistic 99%ile and chasing a meaningless raw-mark number.
This guide breaks down exactly how CAT scoring works: the raw-to-percentile mapping for the last four CAT papers, why normalization exists across slots, what overall and sectional percentiles mean, and the concrete numbers you should target for each percentile band.
CAT Marking Scheme
| Question Type | Correct | Wrong | Unattempted |
|---|---|---|---|
| MCQ (with 4 options) | +3 | –1 | 0 |
| TITA (Type In The Answer, no negative) | +3 | 0 | 0 |
Total questions: 66. Maximum raw score: 198 (if all 66 correct). Time: 120 min, sectional time-locked. Approximate split: 49 MCQs + 17 TITAs.
Raw Score to Percentile — Historical Mapping
This is what each percentile actually cost in raw marks across the last four CAT papers:
| Percentile | CAT 2024 (Moderate) | CAT 2023 (Slightly tough) | CAT 2022 (Moderate) | CAT 2021 (Tough) |
|---|---|---|---|---|
| 100 | ~178+ | ~172+ | ~180+ | ~165+ |
| 99.9 | ~165 | ~158 | ~168 | ~152 |
| 99 | ~152–158 | ~145–152 | ~155–162 | ~142–150 |
| 98 | ~135 | ~128 | ~140 | ~125 |
| 95 | ~115–122 | ~108–115 | ~118–125 | ~102–110 |
| 90 | ~95 | ~88 | ~98 | ~85 |
| 85 | ~80 | ~74 | ~82 | ~70 |
| 80 | ~68 | ~62 | ~70 | ~58 |
Key takeaway: CAT 2021 (tough) had a 99%ile cutoff at ~145, CAT 2022 (moderate) at ~160. A 15-mark gap purely from paper difficulty. This is why percentile matters more than raw score — the system normalizes it.
Why CAT Has Slot Normalization
CAT is held in 3 slots on a single day (forenoon, afternoon, evening). Each slot has a different question paper. To ensure fairness, IIMs apply slot normalization:
- Raw scores are calculated per slot.
- Slot-wise percentiles are computed (your rank within your slot).
- A scaling formula adjusts for slot difficulty — students in tougher slots get a slight upward correction.
- The final scaled score is what determines your overall percentile.
Translation: even if your raw score is 145 and someone else's is 150, if your slot was tougher, you might end up with a higher percentile. You can't game this — focus on maximizing your raw score in your own slot.
Sectional vs Overall Percentile
CAT generates four percentiles for every aspirant:
- VARC sectional percentile
- DILR sectional percentile
- QA sectional percentile
- Overall percentile
IIMs apply both overall and sectional cutoffs:
| IIM Tier | Overall %ile | Sectional %ile (per section) |
|---|---|---|
| IIM A / B / C / L / I / K | 99+ | 85–90 |
| New IIMs (Trichy, Udaipur, Rohtak, etc.) | 96+ | 80–85 |
| Baby IIMs (Bodh Gaya, Jammu, Sambalpur, etc.) | 92+ | 75–80 |
| Top non-IIMs (FMS, MDI, SPJIMR, IIFT) | 98+ | 85+ |
The trap: A 99.5 overall %ile with 70%ile in QA = automatic rejection from IIM A. Sectional balance matters more than peak overall score.
The Decision Tree: What Percentile Should You Target?
What's your goal IIM?
- IIM A / B / C
- Target: 99.5+ overall, 90+ in every section Raw score target: 165+
- IIM L / I / K (older IIMs)
- Target: 99+ overall, 85+ in every section Raw score target: 155+
- New IIMs (Trichy, Udaipur, Rohtak, Ranchi)
- Target: 97+ overall, 82+ in every section Raw score target: 130+
- Baby IIMs (Bodh Gaya, Jammu, etc.)
- Target: 93+ overall, 78+ in every section Raw score target: 105+
- Top non-IIMs (FMS, MDI, SPJIMR)
- Target: 98+ overall (98.5+ for FMS)
- Raw score target: 145+
How to Improve Percentile Without Just Adding Marks
- Reduce negative marking. Two extra wrong answers = –2 marks = often a 0.5 percentile drop near 99.
- Attempt all TITAs you're 70%+ confident on. Zero negative marking — pure upside.
- Don't sacrifice section balance for one peak section. Sub-90%ile in any section caps overall potential.
- Improve weakest section by 5 percentile points. This often shifts overall by 1–2 percentile — more than improving an already-strong section.
- Practice slot-stamina. 99%ile scorers maintain accuracy in the third section. Many aspirants drop 5–10 marks in QA from cognitive fatigue.
The 5 Score-Misinterpretation Mistakes
- Comparing raw scores across years. A 130 in CAT 2021 was 96.5%ile; in CAT 2022 it was ~91%ile. Always benchmark against the same year's mock or paper.
- Targeting raw score without percentile context. "I want to score 150" is meaningless if you don't know what year/difficulty you're calibrating against.
- Ignoring sectional cutoffs. 99.7 overall + 75 sectional = no IIM call.
- Trusting unofficial percentile predictors. Most online predictors use outdated mappings. Use IIM official percentile band only.
- Underestimating the 95→98 gap. Going from 95 to 98 needs ~25 more raw marks. From 98 to 99 needs another 15. The curve steepens.

Frequently Asked Questions
What is the difference between raw score and percentile in CAT?
Raw score is the actual marks scored on the exam (out of 198). Percentile is your relative rank — the percentage of test-takers who scored below you. A 99 percentile means you outscored 99% of all CAT takers, regardless of raw score. IIMs select on percentile, not raw score.
How is the CAT percentile calculated?
Percentile = (Number of candidates with score ≤ yours / Total candidates) × 100, calculated separately for each slot, then normalized across slots using IIM's scaling formula. The final percentile is rounded to 2 decimal places.
What is a good CAT score?
For top IIMs (A/B/C/L/I/K), aim for 99+ percentile (raw score 155–165). For new IIMs, 96+ percentile (raw score 125–135). For baby IIMs and good non-IIMs, 92+ percentile (raw score 100–115). Always check sectional percentile cutoffs separately.
Why is sectional percentile important?
IIMs apply both overall and sectional cutoffs. A 99.7 overall percentile with 70%ile in any one section = no shortlist. Sectional cutoffs at top IIMs are typically 85–90%ile. Balance matters more than peak in one section.
Can two students with the same raw score have different percentiles?
Yes. If they wrote different slots with different difficulty levels, slot normalization will give them different scaled scores and percentiles. The student in the tougher slot gets a slight upward correction.
