CAT Normalization Process- CAT 2025 was conducted across three slots, and as expected, each slot had its own level of difficulty, especially in DILR and Quant. While VARC showed some stability, the remaining sections varied enough to impact student performance across slots.
Since every slot plays out a little differently, IIMs use a fair and scientific normalization process to make sure no student is unfairly advantaged or disadvantaged.
In this detailed guide, we break down what CAT normalization means, why it is required, and how it influences your section-wise and overall scores.

What Is CAT Score Normalization?
Normalization simply adjusts scores so that all slots feel equal- whether your slot was tough, easy, or somewhere in between. In simple terms, normalization ensures that, if your slot was tougher, your score gets scaled up and if your slot was easier, your score may be scaled down. The goal is straightforward to ensure fairness between candidates of Slot 1, Slot 2, and Slot 3.
CAT is a national-level exam with lakhs of test-takers. Therefore, even a slight difference in difficulty can lead to major score discrepancies. Normalization eliminates this inequality.
Why Is Normalization Needed in CAT 2025?
Here is a quick look at how the slots compared:
| Section | Slot 1 | Slot 2 | Slot 3 |
| VARC | Moderate | Moderate | Easy-Moderate |
| DILR | Moderate-Difficult | Moderate-Difficult | Moderate |
| QA | Slightly tricky | Moderate with non-straightforward Algebra | Tougher than others |
These variations explain why normalization is required:
- If all the papers were identical across slots, there would be no need for normalization.
- But when VARC turns out to be easier in one slot, while QA or DILR becomes significantly tougher in another, directly comparing raw scores becomes unfair.
- That’s exactly why CAT uses normalization to balance out these slot-wise differences and ensure every candidate is judged on equal footing.
How the CAT 2025 Normalization Process Works
Normalization in CAT is done to ensure that students from all three slots are evaluated on an equal footing. Since every slot has slight differences in difficulty, the scores are adjusted to bring everyone to the same scale.
Here’s the simplified, student-friendly breakdown.
STEP 1: Raw Scores Are Calculated First
Before normalization, CAT calculates your raw score using the standard marking scheme:
- +3 for every correct answer
- –1 for every incorrect MCQ
- 0 for TITA and unattempted questions
You receive three separate raw scores- one each for VARC, DILR, and QA. These raw scores form the base for the normalization process.

STEP 2: Each Section Is Normalized Separately
This is where the slot-wise balancing happens.
CAT does not release its exact formula, but it has clearly stated that it uses statistical comparisons to adjust for differences in difficulty across slots. These comparisons look at overall performance trends such as:
- How students in each slot performed in a particular section
- Whether a section was noticeably easier or tougher in one slot
- How the score distribution varied across slots
Based on these indicators:
- If a section was tougher in a slot, scores from that slot are usually adjusted slightly upward.
- If a section was easier, scores from that slot may see a mild downward adjustment.
The most important part:Normalization is done section-wise, not on the total score. So difficulty differences in one section do not impact another.
STEP 3: Normalized Sectional Scores Are Combined
Once all three sections are normalized individually, CAT adds them together:
Normalized VARC + Normalized DILR + Normalized QA = Overall Normalized Score
Your percentile is then calculated only from the normalized scores, not from the raw scores.
This is why two students with identical raw scores may still end up with different percentiles- their slot difficulty was different, so their normalized scores also differ.
How Normalization Likely Impacted CAT 2025
Based on the difficulty variations observed across slots, here’s the expected impact of normalization:
VARC
- Slot 3: Since Slot 3 VARC was relatively easier, it may see slight scaling down.
- Slot 1: VARC was moderately challenging → slight scaling up expected.

DILR
- Slot 3: Easier sets compared to Slot 1 & 2 → expect some downward scaling.
- Slot 1 & Slot 2: More difficult sets → normalization should benefit these slots.
- For example, a raw score of 20 in DILR might shift differently depending on your slot. In a tougher slot, it may get bumped up slightly, while in an easier slot, it might stay the same or scale down. This is completely normal.
Quant (QA)
- Slot difficulty was almost uniform, except Slot 3 being slightly tougher.
- Therefore, minimal scaling expected overall, with Slot 3 possibly getting a small upward adjustment.
Overall, candidates from tougher sections within their slot stand to gain slightly from normalization, while those from easier sections may see a balanced downward calibration.

Key Takeaways for CAT Aspirants
- Normalization ensures fairness, slot difficulty does not affect your final percentile.
- Sections are normalized individually, this prevents students from gaining an advantage in one easy section and carrying it over to others.
- Percentile = based on normalized score, not raw marks.
- Even a small difference of 2-5 marks after normalization can shift percentile margins significantly, especially between 70-90 percentile.
- If your slot felt extremely difficult, don’t panic. Normalization often works in your favour.
Conclusion – CAT Normalization Process
Normalization is one of the most important aspects of CAT scoring, ensuring that every student- no matter the slot gets a fair, accurate, and unbiased evaluation. CAT 2025 had noticeable slot-wise difficulty differences, especially in DILR and QA, and normalization effectively balanced these variations.
At the end of the day, your normalized score shows how well you performed compared to thousands of other students- not just how tough your slot was.

FAQs
Q: Does CAT normalize section-wise or overall?
A: CAT normalizes each section separately and then adds them to create the overall normalized score.
Q: Will an easy slot decrease my normalized score?
A: Yes. If your slot was significantly easier in a section, your normalized score for that section may be adjusted slightly downward to maintain fairness.
Q: Does normalization benefit students from tougher slots?
A: Yes. If your slot had a tougher section- like Quant or DILR normalization adjusts your score upward to match the overall difficulty level. This ensures that candidates from more difficult slots are not at a disadvantage compared to those from easier slots.
Q: Can normalization change my percentile a lot?
A: Absolutely. Normalization has the highest impact between 60-95 percentile, where every mark can shift percentile by multiple points.
