Cracking the National Defence Academy (NDA) is not just about clearing an exam. It’s about shaping yourself into a future officer of the Indian Armed Forces. For students in Class 10 and 12, early preparation can make the difference between attempting NDA and clearing it with confidence.
This blog offers a clear, realistic, and practical NDA preparation roadmap for 2026, covering academics, physical fitness, and the all-important SSB interview.
Why Early NDA Preparation Matters
NDA is a long-term goal, not a last-minute sprint. Starting early helps you:
- Build strong fundamentals in Maths and General Ability
- Develop discipline and time management
- Gradually improve physical fitness
- Cultivate Officer-Like Qualities (OLQs) naturally
- Reduce pressure during Class 12 board exams
Students who start in Class 10 or early Class 11 have a huge advantage over late starters.
Understanding the NDA Selection Process
Before planning preparation, it’s important to understand the three stages of NDA selection:
1. NDA Written Examination (UPSC)
- Mathematics (300 marks)
- General Ability Test (600 marks)
2. SSB Interview (5 Days)
- Psychological Tests
- Group Testing Officer (GTO) Tasks
- Personal Interview
- Conference
3. Medical Examination
- Physical and medical fitness as per defence standards
Clearing NDA requires balanced preparation, not just bookish knowledge.
