Cracking the National Defence Academy exam is a dream for thousands of aspirants who want to serve the nation with pride. While most candidates prepare for months, many successful selections have proven that even 50 days of focused and disciplined preparation can make a huge difference — if you follow the right strategy.
🎯 Understanding the Challenge
Before jumping into preparation, you must understand what you are preparing for.
The NDA written exam has two papers:
1. Mathematics (300 marks)
2. General Ability Test – GAT (600 marks)
- English
- Physics, Chemistry, Biology
- History, Geography, Current Affairs
Success depends on concept clarity, speed, accuracy, and consistency.
🗓️ 50-Day NDA Study Plan (Phase-wise)
✅ Phase 1: Concept Building (Day 1–15)
This phase is all about strengthening fundamentals.
Mathematics
- Revise NCERT Class 9–12 basics.
- Focus on algebra, trigonometry, mensuration, and coordinate geometry.
- Solve at least 25–30 questions daily.
English
- Practice grammar rules (tenses, prepositions, voice, narration).
- Learn 10–15 new vocabulary words daily.
- Read editorials or short articles for comprehension.
General Science
- Revise basic Physics and Chemistry formulas.
- Study Biology fundamentals (human body, plant systems, ecology).
Goal: Clear concepts, no confusion, strong basics.
✅ Phase 2: Practice & Strengthening (Day 16–35)
Now it’s time to move from learning to applying.
Mathematics
- Start topic-wise mock tests.
