How CAT Scoring Works
The Common Admission Test (CAT) is scored using a straightforward marking scheme applied uniformly across its three sections — Verbal Ability & Reading Comprehension (VARC), Data Interpretation & Logical Reasoning (DILR), and Quantitative Ability (QA):
- +3 marks for every correct answer
- −1 mark for every incorrect MCQ (multiple-choice question)
- 0 marks (no penalty) for incorrect TITA (Type In The Answer) questions
- 0 marks for unattempted questions
Your raw score is simply the sum of marks earned this way. This calculator applies exactly that formula: Raw Score = (Correct × 3) − (Incorrect MCQ × 1).
Why Raw Score Isn't the Same as Percentile
CAT does not publish a fixed score-to-percentile conversion table, because the exam is conducted in multiple slots with different question sets and difficulty levels. To ensure fairness, the testing authority applies a statistical process called equi-percentile normalization, which adjusts raw scores from each slot based on the relative difficulty and the performance distribution of candidates in that slot, before converting to a percentile out of all ~2-3 lakh test takers.
This means two candidates with the identical raw score in different slots can end up with slightly different percentiles. Because of this, any percentile shown by a raw-score calculator — including this one — is necessarily an estimate based on historical trends, not an official or guaranteed figure.
How to Use Your Estimated Percentile
Use the percentile band from this calculator as a rough directional indicator only, useful for:
- Getting a quick sense of how your attempt compares to previous years' trends immediately after the exam
- Deciding whether to start preparing applications/SOPs for your target B-schools while waiting for official results
- Benchmarking your mock test performance against real exam-day scoring patterns
For an authoritative estimate, always cross-check with the official CAT percentile predictor tools released by IIMs or reputed coaching institutes shortly after each exam slot, which incorporate that year's actual difficulty level and response patterns.
Tips to Improve Your Effective Score
Because incorrect MCQs cost you marks, accuracy matters as much as speed. Many high scorers deliberately skip questions they are unsure about rather than guessing, since a wrong MCQ guess costs 1 mark while an unattempted question costs 0. TITA questions, having no negative marking, are often worth attempting even with moderate confidence.
