1. The Pattern Card.

• Therefore, the structure.** Three sections, 120 minutes, 40 minutes each (sectional locked — you cannot return to a closed section) : VARC (24 questions). DILR (22) , QA (22)** — the 2021-onward pattern (68 questions total. Therefore, the 2014-19 era was 100-question/180-minute — know the current one).
• Meanwhile, the marking.** +3 / −1 for MCQs; TITA (Type-In the Answer) questions carry no negative marking**; roughly 20-25% of the paper is TITA — the free guess zone.
• As a result, computer-based, three slots (morning-afternoon-evening) on one-or two days in November — the slot variance that makes normalisation necessary.

2. Section-by Section Composition.

• VARC (24 Q, 40 min). In other words, 16 RC questions (4 passages) + 8 verbal ability questions (parajumbles, para-summary. Meanwhile, odd-sentence-out — mostly TITA) — RC is two thirds of the section; the verbal 8 are the speed layer.
• DILR (22 Q, 40 min). Notably, ~5 sets of 4-5 questions (a mix of data and logical sets). As a result, the notorious section — set selection is half the game (Part 3’s method).
• QA (22 Q, 40 min). Indeed, arithmetic heavy (~40%: time-work, ratios, percentages, profit-loss, time-speed-distance), algebra (~25%). In other words, geometry (~15-20%), numbers-and modern math the rest — Part 4’s chapter priorities flow from this distribution.

3. Scoring, Normalisation and Scaling.

• The scaling logic. Specifically, different slots differ in difficulty; the IIMs’ normalisation (the scaled score) adjusts across slots before percentiles are computed — you are compared against your own slot first. Then equated; the exact formula is unpublished (an equi percentile logic). Notably, the implication is clear: difficulty is not a disadvantage — performance relative to your slot is what counts.
• The percentile maths. Similarly, a 99 percentile means 1% of candidates scored above you. Indeed, the composite percentile and the sectional percentiles both matter — most IIMs shortlist on sectional cutoffs (typically 70-85+ sectional for the calls) plus the overall — the reason “strong QA, weak VA” profiles stall.
• The score to percentile reality. Overall, recent years: ~ 45-50/198 raw ≈ 99 percentile (with accuracy mattering more than attempts — 60% accuracy on 40 attempts loses to 90% on 28); the normalised-vs-raw distinction in scorecards.

4. What the Pattern Implies Strategically.

1. Consequently, the sectional clock forces balance — no hiding from a weak section. Specifically, the 40-minute lock makes sectional time management (not overall) the skill.
2. Furthermore, the TITA layer rewards attempts — no negative marking means every TITA gets an answer. The MCQ discipline (Part 5’s accuracy maths) applies only to MCQs.
3. Likewise, the selection game — in DILR and QA, choosing which 12-15 of 22 to attempt is worth more than solving ability alone.
4. In short, the 40-minute rhythms — practice every section under exact 40-minute clocks from month one; stamina and pacing are pattern-specific.

5. Registration-and Process Facts.

• Subsequently, registration August-September; admit cards October-November; the exam late November; results December-January — the WAT-PI season January-April (Part 7).
• In fact, bachelor’s with 50% (45% reserved); final year students eligible — the standard card.
• The conducting rotation. Moreover, the IIMs rotate the conduct (IIM Calcutta 2024. So on) — the notification’s details (question count tweaks) can shift slightly year to year. Always verify the current year’s official mock.

6. How Exams Probe This Topic.

• Therefore, the real test — but the pattern knowledge shapes every practice decision: mock analysis by slot normalised percentiles. Sectional cutoffs as targets, and the TITA-MCQ split in accuracy tracking.
• Meanwhile, cross-reference: Parts 2-4 (the sectional methods), Part 5 (the percentile maths), Part 8 (the multi exam calendar this pattern enables).

7. Quick Revision: One-Glance Facts.

• 3 sections ×40 min; VARC 24 / DILR 22 / QA 22; +3/−1 MCQ; TITA no-negative.
• RC = 16/24 VARC; QA’s arithmetic ~40%.
• Slot normalisation; sectional cutoffs govern calls; ~45-50 raw ≈ 99%ile.
• Selection + sectional pacing + TITA attempts = the pattern’s strategy.

CAT’s pattern is a strategy document: three locked 40-minute sections, a two-thirds-RC verbal. A selection driven DILR, an arithmetic first QA, and scaling that neutralises slot luck. Every later part of this series assumes this architecture — fix these numbers and your preparation plan builds on bedrock.

Practice Corner: Five Pattern Checks (with Answers).

1. CAT’s three sections and their sectional times? — VARC 24, DILR 22, QA 22 — 40 minutes each, locked .
2. — +3/−1 for MCQs; TITA has no negative .
3. Why does scaling exist? — Three slots differ in difficulty; you compete within your slot first .
4. What governs IIM shortlists besides the overall percentile? — Sectional cutoffs (~70-85+) .
5. The raw-to-99 percentile guide?

The Slot-Day Mindset Card (Read on Exam Morning).

Slot difficulty is normalised — a hard slot is not a disadvantage. The “my slot was tougher” thought is banned. What matters is performance relative to your slot, which you control. Sectional locks mean no borrowing — the 40 minutes end when they end. The three pass discipline inside each lock is the whole game. TITA has no negative — every TITA gets an answer, always. And the day’s only real enemy is the one question you refuse to leave: one 6-minute sunk cost in section one costs three unseen sitters in section three. Four lines, printed on a card, read twice on exam morning — the pattern’s strategic content compressed to what fits in a shaking hand’s pocket.

The Normalisation-Mechanics (What the Score-Actually-Is).

The scaled-score’s inner-working for the exam-mind: the raw-score’s section-and slot composition (the ~66-72-attempt-paper’s raw and the accuracy’s arithmetic). The equi-percentile-equitng’s logic (the slot’s internal-rank preserved and the cross-slot-distribution matched — the reason a harder-slot’s-44-equals an easier-slot’s-48). The scorecard’s twin reporting (the raw and the scaled with the sectionals’ scaled-too). And the percentile’s computation order (the scaled Then the percentile — never the raw-directly). the practical-corollaries: the mock-to mock’s score-comparison’s validity (only the percentile-bands-compare-across different-mocks’ difficulty). The sectional-cutoff’s scaled nature (the ~80-85-sectional bands the calls-require). And the one-actionable rule — prepare to the percentile-band not the raw-score (the 99-band’s raw-moved-year-to year with the difficulty; the band’s competence is the constant).

The Pattern-Variance-Protocol (When the Notification-Changes).

The 2021-and-2025’s pattern-shifts taught the protocol: the notification’s release-day-five checks (the sections-and counts. The timing and the sectional-locks; the marking and the TITA-share; the interface’s changes; the schedule); the preparation’s impact assessment (the VARC-24-versus the earlier-32’s reading-time’s shift — the two-passage-reduction’s-40-minute’s reallocation; the QA’s-22’s arithmetic-emphasis’s amplification); and the mock-plan’s adjustment window (the final-two-months’ mocks in the new-pattern only — the old-pattern’s mocks’ metrics-recalibrated by the bands not the scores). the protocol’s rule: the pattern-changes favour the adaptable not the finished — and the notification’s day is the adaptation’s day-one.

The TITA-Fraction Arithmetic (The Pattern’s Hidden Gift).

One pattern fact deserves its own spotlight: roughly a fifth to a quarter of CAT’s questions are TITA — type in the answer. With no negative marking — and their distribution is not random. TITA clusters in QA’s short answer items and DILR’s non-MCQ sets. Means the candidate who tracks the TITA share question by question through mocks learns to treat those items as mandatory attempts regardless of confidence: a wrong TITA costs nothing. A blank TITA is the only true zero on the paper. The arithmetic is unambiguous — across a typical paper of 15 TITA items. The always attempt policy versus the skip when unsure policy differs by two to three net marks. On the compressed percentile scale is a full band. Print one-line on your exam-day card: every TITA gets an answer, always; the MCQ discipline stays ruthless.
