How to Crack CAT Exam

What is CAT Exam?

CAT (Common Admission Test) is the national entrance exam for admission to MBA programmes at IIMs and 1,200+ other business schools in India. Conducted by IIMs on a rotational basis, CAT is one of India's most competitive exams with over 3 lakh aspirants each year competing for approximately 4,000-5,000 seats at IIMs.

CAT exam date: Typically the last Sunday of November. Notifications come out in July-August.

Eligibility: Bachelor's degree in any stream with minimum 50% marks (45% for SC/ST/PwD). Final-year graduation students can also apply.

Result: CAT results come out in January. IIMs shortlist candidates based on percentile, academic record, work experience and diversity. The process continues with WAT (Written Ability Test) and PI (Personal Interview) in February-March.

CAT Exam Pattern and Sections

CAT has three sections:

1. Verbal Ability and Reading Comprehension (VARC) — 40 minutes, 24 questions Reading Comprehension passages (RC) — 16 questions from 4 passages Verbal Ability — 8 questions (Para Jumbles, Para Summary, Odd One Out, Para Completion)

2. Data Interpretation and Logical Reasoning (DILR) — 40 minutes, 20 questions Data Interpretation sets (Tables, Graphs, Charts, Caselets) Logical Reasoning sets (Arrangements, Grid, Games and Tournaments, Binary Logic)

3. Quantitative Aptitude (QA) — 40 minutes, 22 questions Arithmetic (40%), Algebra (25%), Geometry (20%), Number Theory and Modern Maths (15%)

Total: 66 questions, 120 minutes. Scoring: +3 for correct MCQ answers, -1 for wrong MCQ answers. TITA (non-MCQ) questions: +3 for correct, 0 for wrong.

CAT Preparation Strategy: Section-wise

VARC Preparation: Read quality English daily: The Hindu, The Economist, Harvard Business Review articles. Reading improves comprehension speed and vocabulary. RC strategy: Don't read the passage fully first. Read the questions, then read the passage actively to answer them. Verbal Ability: Para Jumbles and Para Summary require practice. Solve 5-10 per day from previous CAT papers.

DILR Preparation: This is the most time-consuming section. Quality over quantity — in 40 minutes you need to pick 2-3 sets and solve them completely rather than attempting all 5-6 sets poorly. Practice speed: Solve DI-LR sets from CAT 2010-2024. The difficulty changes year to year — exposure to variety is key. Mental math: Calculating percentages, ratios, and averages quickly is essential for DI.

QA Preparation: Class 10-12 Maths is the foundation. If your basics are weak, start with NCERT Class 9-10. Arithmetic (Time-Speed-Distance, Profit-Loss, Percentages) has the highest weightage in recent CATs. Geometry (Circles, Triangles, Coordinate Geometry) is high-yield — 4-5 questions per year. Solve 50 QA problems daily at minimum.

CAT Preparation Timeline

Here is a recommended preparation timeline:

12-15 months before CAT: Build fundamentals — Class 10-12 Maths, basic English reading habits, start one mock test monthly to understand current baseline.

9-12 months before CAT: Chapter-wise study for QA (finish all arithmetic, algebra, geometry). Start structured VARC practice. Begin DILR with basic sets.

6-9 months before CAT: Increase mock frequency to 2 per week. Identify weak areas. Review every mock in detail.

3-6 months before CAT: Full syllabus revision. 2-3 mocks per week. Dedicated time for DILR (most people's weakest area).

Final 3 months: Intensive mock practice (3-4 per week), error analysis, targeted weak area revision.

Final month: 4-5 mocks per week. Exam simulation: take mocks at 9 am (the typical CAT time slot). Focus on strategy refinement, not new content.

How Many Mock Tests to Take for CAT

Mock tests are the most important part of CAT preparation. Here is a sensible mock test strategy:

Minimum mocks: 50 full-length mock tests over your preparation period. Frequency: 1-2 per week for the first 6 months; 3-4 per week in the final 3 months. Sources: IMS, TIME, CL (Career Launcher), and official CAT past papers are all valuable. Official past papers (2010-2024) are the best quality. Analysis ritual: For every mock, spend 90-120 minutes in analysis. Identify: (1) Which questions should I have attempted/skipped, (2) Where did I lose time, (3) What is my section-wise accuracy. Target score: 99 percentile typically requires 55-60 correct answers out of 66. 95 percentile requires approximately 45-48 correct answers.

CAT Score Required for IIM Admission

IIM shortlisting percentiles vary by IIM:

IIM Ahmedabad, Bangalore, Calcutta (top 3): Overall 99-99.5 percentile typically needed. Sectional cutoffs: 85+ percentile per section.

IIM Lucknow, Kozhikode, Indore, Shillong: 95-98 percentile overall.

New IIMs (Trichy, Udaipur, Rohtak, etc.): 85-95 percentile overall.

Note: IIMs use a composite score that includes CAT score + academic performance + work experience + diversity. Work experience of 2-3 years from top companies can lower the CAT percentile needed by 2-3 points.

Non-IIM top colleges: FMS Delhi (99+ percentile), XLRI Jamshedpur (uses XAT), IIFT, MDI Gurgaon, SP Jain, JBIMS — all require 95-99 percentile CAT or their own specific exam.
