IIT JAM 2026 Preparation Strategies
Based on 2025 paper analysis and topper interviews:
1. Three-Phase Preparation Plan
Phase 1 (Jun-Aug 2025): Conceptual clarity using standard textbooks
Phase 2 (Sep-Nov 2025): Topic-wise practice + 2 papers/week
Phase 3 (Dec-Jan 2026): Full-length mocks + weak area revision
2. Section-Wise Approach
Section A: Target 90% accuracy (1 mark questions)
Section B: Focus on high-yield topics first
Section C: Develop frameworks for 2-mark problems
3. Paper Solving Technique
- First solve papers untimed for understanding
- Gradually reduce to 2.5 hours per paper
- Maintain error log with mistake classification
