Strategies to Score High in INMO
Learn the exact strategies that our top performers use to maximize their scores in the Indian National Mathematical Olympiad.
| Time Period | Strategy Focus | Key Actions |
|---|---|---|
| Before Exam (12-18 months) | Concept Mastery | Complete understanding of theorems, multiple problem approaches, formula sheets creation |
| Before Exam (6-12 months) | Past Paper Analysis | Solve 10+ years of INMO papers, time yourself, understand official solutions |
| Before Exam (3-6 months) | Problem Bank Creation | Categorize solved problems, note innovative solutions, regular review |
| During Exam (First 30 mins) | Problem Assessment | Read all problems without solving, classify by familiarity, create attempt order |
| During Exam (Next 3 hours) | Strategic Solving | 45-50 mins max per problem, move if stuck, clear solution presentation |
| During Exam (Last 30 mins) | Review & Refinement | Check all solutions, ensure clarity, maximize partial credits |
