CAT Answer Key 2026: Score Yourself + 3-Step Objection

CAT Answer Key 2026: Score Yourself + 3-Step Objection

By Optima Learn Editorial Team · Published May 17, 2026 · 8 min read

The CAT 2026 answer key is the most expensive 72-hour window in the CAT cycle. Most aspirants treat it as a passive download. The ones who treat it as an active checkpoint walk into result day with a calibrated percentile estimate and, occasionally, a corrected scorecard worth 5 to 10 percentile points.

This guide covers the four documents released after the exam, how to self-score using the +3, -1, 0 formula, the 3-step objection process with fee, and what comes next when the official scorecard drops in late December.

The Four Documents Released After CAT 2026

The window between the exam day and the result drops produces four distinct documents on iimcat.ac.in. Each one serves a different purpose. Confusing them is the single most common error among first-time CAT aspirants, who often think the response sheet is the result and panic-calculate when the numbers look low.

Document 1: Response sheet. The candidate-specific record of every answer marked during the exam, sectional time spent, and a per-question status. Released first, around December 3 to 5. Downloaded with CAT user ID and password from registration. Includes the question paper images, so you can re-read the exact questions you attempted.

Document 2: Official answer key. The IIM Indore expert panel's official correct answer for every question across all slots. Released alongside or shortly after the response sheet. Same for all candidates within a given slot; different slots have different answer keys because the question papers differ. The official key is what your response sheet is scored against.

Document 3: Final answer key. The revised official key after the 48 to 72 hour objection window closes and the expert panel reviews submitted challenges. Released around December 18 to 20. This is the key used for the result scorecard. Around 1 to 3 questions per slot are typically dropped or have their answers revised based on accepted objections.

Document 4: Scorecard. The final document, released late December alongside the result. Contains sectional raw scores, scaled scores after normalization, sectional percentiles, and the composite percentile. The scorecard is what IIMs and non-IIM B-schools use for shortlist decisions.

Response Sheet vs Answer Key: What Each Document Shows

The response sheet and the answer key are released within hours of each other but serve different functions. Aspirants who download both and lay them side by side can self-score in 30 minutes. Aspirants who confuse the two often miscalculate by 8 to 15 marks and arrive at a wildly wrong percentile estimate.

The CAT 2026 Raw Score Formula (Self-Calculation in 30 Minutes)

The raw score uses a simple three-rule formula. Apply it question by question across all three sections to land on your raw total. The maximum raw score is 198 across 66 questions; sectional maximums are VARC 72 (24 questions), DILR 60 (20 questions), QA 66 (22 questions).

Add the three sectional raw scores to get the composite raw total. Match each section's correct count against the answer key, your TITA wrong count against the response sheet (TITA wrongs are visible because the response sheet shows your input), and the MCQ wrongs by elimination. The whole calculation takes 25 to 35 minutes per slot. Working professionals should block a Saturday morning between December 5 and 8 for the exercise so the objection window stays open if you spot a disputable question.

The 3-Step CAT 2026 Answer Key Objection Process

The objection window opens with the answer key release and stays live for 48 to 72 hours, typically closing on December 7 or 8 at 5 PM IST. The window does not extend. Objections submitted after the deadline are not considered, even if the technical case is valid. The process moves in three steps on iimcat.ac.in.

The CAT 2026 Post-Exam Timeline at a Glance

The full post-exam runway runs from late November to late December. Each window has a specific action; missing the window means the action is no longer available. The table below is the forecast based on the past five CAT cycles, with the working dates for CAT 2026.

What to Do with Your Raw Score Before the Scorecard Drops

The two weeks between self-score (around December 6) and scorecard release (around December 21) are often misused. Most aspirants either obsess over the raw number daily or check out completely. Both approaches waste a critical window. Three productive actions to take in this fortnight:

1. Convert raw to percentile band using a validated predictor. A self-calculated raw score of 90 to 100 maps roughly to a 90 to 95 percentile band; 110 to 120 maps to 95 to 98; 130+ maps to 99+. But the exact band depends on slot difficulty. Use a predictor that factors in slot-wise difficulty patterns, not a flat raw-to-percentile table.
2. Start IIM shortlist research based on the band. Different IIMs weight CAT percentile, academics, gender diversity, and work-ex differently. The Optima Learn IIM cutoff 2026 IIM-wise guide shows the percentile bands needed at each IIM. Plan a target shortlist now instead of after the scorecard.
3. Begin WAT-PI prep if you are in the 95+ percentile band. Shortlists for top-tier IIMs come in January, with the first WAT-PI rounds in February. Three weeks of WAT-PI prep starting December 10 is significantly more useful than three weeks starting January 5.

Aspirants below the 90 percentile band can still use this window to start parallel applications to non-IIM CAT-accepting B-schools, which have separate deadlines. The Optima Learn non-IIM MBA colleges CAT 2026 guide covers the application calendar for SPJIMR, MDI, IIFT, NITIE, and similar institutes.

How Self-Score Connects to Mock Analysis

The self-score exercise after CAT 2026 is the highest-fidelity version of mock analysis you will ever do. The same framework used to debrief October mocks applies to the final exam: section-wise raw scores, question-wise correctness, time-per-question patterns, and elimination rate on incorrect attempts. Aspirants who treated mock analysis as a serious framework all year arrive at post-exam self-score with the muscle memory to extract every signal from the response sheet.

The Optima Learn CAT mock test analysis framework walks through the per-section debrief structure that converts cleanly to a post-CAT self-score. The Optima Learn CAT score vs percentile 2026 guide bridges the raw-to-percentile gap once your self-score is in.

Self-score is the first calibration. Objection is the second. Both close within 72 hours of the answer key drop. Plan the window now.
