How to Prepare for IIM Entrance Exam 2025 – Step-by-Step Strategy

Preparing for the IIM entrance exam, i.e., CAT 2025, requires consistent effort, smart planning, and structured revision. Since the entrance exam for IIM is highly competitive, your preparation must be phase-wise to build both speed and accuracy across all three sections — VARC, DILR, and QA.

Here's a month-wise breakdown to help you prepare for the IIM entrance exam in a systematic and achievable manner:

Months 1–2: Build Your Foundation

This is the concept-building phase, where your focus should be on strengthening your basics across all sections.

Quantitative Aptitude (QA)

• Focus on Arithmetic topics like percentages, profit & loss, time & work, and averages. These form the largest chunk of the Quant section.
• Use beginner-friendly books like Arun Sharma (Quant) or Nishit Sinha to understand core concepts.

Verbal Ability & Reading Comprehension (VARC)

• Read 2–3 articles daily from sources like The Hindu, Aeon Essays, or New York Times.
• Solve at least 2 RCs per day, focusing on accuracy and comprehension.
• Start practicing Para jumbles and Odd one out questions.

Data Interpretation & Logical Reasoning (DILR)

• Begin with basic DI sets (bar charts, tables, pie charts).
• Solve one LR puzzle daily, such as seating arrangements, Venn diagrams, or binary logic.
• Build comfort with understanding data quickly under time constraints.

Goal: Build accuracy, understand core logic, and develop reading habits essential for cracking the iim entrance exam.

Months 3–5: Strengthen Skills & Begin Testing

This is your skill enhancement phase — transition from learning to testing.

Topic-wise Practice

• Identify weak and strong areas in each section.
• Solve sectional tests (30–45 mins) focused on individual topics like Time-Speed-Distance or RC summaries.

Join a Test Series

• Enroll in a reputed test series like Coachify CAT Mocks.
• Attempt 1 mock per week and review each test thoroughly.

Mock Analysis (Crucial)

• Post-mock, analyze:
  • Which questions consumed most time?
  • Where did you make careless errors?
  • What was your accuracy in each section?

Track your percentile trend across mocks. The iim entrance exam demands not just solving ability, but exam temperament and strategy.

Months 6–7: Master Mocks & Final Revision

This is your exam-readiness phase, where you simulate the real exam environment and polish your strategy.

Full-Length Mock Tests

• Take at least 15–20 full-length mocks during this time.
• Stick to the exact CAT format (120 mins, sectional time limits).
• Attempt at the same time slot as your actual exam (morning/afternoon/evening).

Sectional Revision

• Revisit notes, formulas, and previously incorrect mock questions.
• For Quant: Practice mixed sets of Arithmetic + Algebra + Geometry
• For VARC: Focus on speed reading and inference-based RCs
• For DILR: Focus on high-level puzzles from previous CATs

Exam Simulation

• Daily 3-hour sessions: 2 hours for a mock, 1 hour for analysis.
• Practice mindfulness and stamina to avoid fatigue in the real exam.

The goal is to be comfortable under pressure, manage time efficiently, and reduce errors in the actual entrance exam for IIM.

Final Tips:

• Don’t ignore sectional timing—each minute matters in the CAT.
• Avoid learning new concepts in the last 15–20 days.
• Focus on mock test feedback more than just scores.
• Keep a balance between revision and mock-taking.

Pro Tip: Many CAT toppers report a 20–30 percentile improvement just by analyzing mocks thoroughly and tweaking their strategies. Make that your edge for the IIM entrance exam 2025.
