🗣️ CAT 2024 Data Interpretation and Logical Reasoning (DI LR) Section Analysis: Slot-Wise Breakdown & Lessons for CAT 2025

In CAT 2024, the DILR (Data Interpretation & Logical Reasoning) section typically comprised 5 sets (an increase from 4 in earlier years), with a mix of DI and LR sets. Out of these, roughly 2–3 sets were DI-focused in each slot. Each DI set had 4–5 questions, often in MCQ and/or TITA formats. Overall difficulty across slots ranged from Easy–Moderate to Moderate, with some slot-wise variation.

🔎 SLOT-WISE DI ANALYSIS

📌 CAT 2024 – Slot 1

• Number of Sets: 5 (3 DI sets + 2 LR sets)
• DI Sets: 3 sets, each with 4 questions
• Difficulty Level: Moderate overall for DI
• Question Types in DI:
  • Graph-based sets (bar charts, line graphs)
  • Table/chart interpretation
  • Mixture of straightforward computations and multi-layered inference
• Format: Mostly MCQs; some TITA questions embedded in DI sets (depending on set)
• Key Observations:
  • DI sets were “moderate”—not very time-consuming individually, but required accuracy in reading and multi-step calculations.
  • Some sets involved combining information from multiple small charts/tables.
  • Careful scanning for relevant rows/columns helped avoid wasted time.
  • Avoided extremely convoluted data; focus was on clear interpretation with 2–3 levels of inference.
• Good Attempts & Accuracy:
  • Attempting about 8–9 DI questions (i.e., about 2 full DI sets plus parts of a third) with ~80–85% accuracy was considered a safe target for a high percentile in the DILR section.

📌 CAT 2024 – Slot 2

• Number of Sets: 5 (2 DI sets + 3 LR sets)
• DI Sets: 2 sets, one with 4 questions, one with 4–5 questions
• Difficulty Level: Easy to Moderate for DI sets
• Question Types in DI:
  • Profitability/table interpretation (e.g., firms’ financial metrics, ratios)
  • Distribution/rating charts (e.g., ecommerce rating distributions, cumulative percentages)
  • Occasionally mixed charts (e.g., combining tabular data with simple graphs)
• Format: Primarily MCQs; some TITA questions in DI sets depending on the set
• Key Observations:
  • Compared to previous year, DI sets were relatively easier—fewer layers of inference.
  • Straightforward computations (e.g., percentage changes, ratios) were common.
  • Candidates reported that clear labeling in charts/tables made data lookup faster.
  • Time saved here could be reallocated to trickier LR sets.
• Good Attempts & Accuracy:
  • Attempting around 6–7 DI questions (i.e., about 1 full DI set plus parts of the second) with ~85%+ accuracy was a good benchmark.

📌 CAT 2024 – Slot 3

• Number of Sets: 5 (2 DI sets + 3 LR sets)
• DI Sets: 2 sets, each with 5 questions
• Difficulty Level: Moderate for DI sets (slightly tougher than Slot 2, but still manageable)
• Question Types in DI:
  • Chart interpretation (e.g., bar graphs on app subscriptions, line graphs on temperature trends)
  • Tabular data (e.g., GDP of countries, financial metrics)
  • Mixed DI (combining multiple small data blocks)
• Format: Mix of MCQs and TITA questions (e.g., 3 MCQs + 2 TITA in a set)
• Key Observations:
  • DI sets had moderate inference depth: often required multi-step filtering (e.g., selecting top/bottom categories, computing derived ratios).
  • Some sets demanded careful attention to detail (units, time periods).
  • Still more straightforward than many LR sets in Slot 3.
  • Candidates with strong tabular reading skills gained time advantage.
• Good Attempts & Accuracy:
  • Attempting around 7–8 DI questions with ~80–85% accuracy aligned with scoring ~27–30 in DILR for a high percentile.

📊 Comparative Snapshot of DI in CAT 2024

🔑 Key Takeaways for CAT 2025 DI Preparation

1. Consistent DI Practice:
   • Regularly solve varied DI sets (tables, bar/line charts, pie charts, mixed data) to build speed in data extraction.
   • Focus on both quick-read tactics (e.g., scanning relevant rows/columns) and deeper inference (e.g., deriving ratios, trends).
2. Accuracy Over Attempts:
   • In DI, wrong answers carry negative marking in MCQs. Prioritize accuracy: if unsure about multi-step inference, skip or mark TITA if confident.
   • Cultivate elimination skills: sometimes a rough estimate of ranges helps eliminate wrong options without full calculation.
3. TITA Familiarity:
   • Many DI sets include TITA questions where negative marking is absent. Practice these to boost safe attempts.
   • Ensure precision, since TITA requires exact values/formats.
4. Time Management:
   • In mocks, allocate ~12–15 minutes for DI (out of 40 for DILR, shared with LR). Adjust based on personal strengths: if DI is a strength, aim to finish DI sets quickly and channel saved time to LR.
5. Varied Difficulty Exposure:
   • CAT DI can vary from very straightforward computations to moderate multi-layered inference. Practice both “easy” and “moderate” DI regularly so you’re prepared for any slot variation.
6. Error Analysis & Logging:
   • Maintain an error log: note the nature of mistakes (data misread, calculation slip, misinterpretation). Review weekly to avoid repeats.
7. Integration with LR Practice:
   • Since DI and LR share the same section, simulate actual test conditions: after finishing DI, switch mindset to LR puzzles. Practice seamlessly transitioning.

📅 CAT 2025 DI Prep Plan (June – November)

Below is a month-wise roadmap focusing on Data Interpretation. Adjust weekly/daily schedules based on your overall prep (VARC, QA, LR). The plan assumes you begin in June 2024–25 cycle and take regular mocks.

  • Last-Minute Revision: Quick review of common DI pitfalls (e.g., unit misalignment, misreading axes). Go through your error log to avoid repeating mistakes.
  • Exam Strategy Drill: Decide slot-wise DI approach (e.g., attempt easier DI sets first in exam, then decide on moderate ones based on remaining time). Practice this in sectionals.
  • Mock Analysis: In last 2 weeks, focus primarily on accuracy rather than chasing higher attempts.
• Outcome: A robust, repeatable DI strategy: quick screening of sets, prioritized attempts, strong accuracy.

• Time Audits: In mocks, note exact time spent on each DI set. If you consistently overshoot, adjust practice difficulty/timing.
• Stress Management: Build confidence by progressively increasing difficulty, so on exam day you remain calm when encountering moderate DI sets.
• Balance with LR: Since DILR is combined, ensure DI practice also trains you to transition smoothly into LR within the 40-minute window.
