In this comprehensive blog by Siddhu Defence Academy, Dehradun, we’ll cover proven strategies, expert tips, and a complete study plan to help you crack the NDA 2025 exam in your first attempt.

Understanding the NDA Exam Structure

Before jumping into strategies, it’s essential to know what you’re preparing for.

The NDA selection process includes two stages:

1. Written Examination (Conducted by UPSC)

2. SSB Interview (Conducted by Service Selection Boards)

NDA Written Exam Pattern

• SSB Interview: 900 Marks

• Grand Total: 1800 Marks

The exam tests conceptual clarity, problem-solving ability, and general awareness — not just memorization.

Step 1: Understand the NDA 2025 Syllabus

A strong foundation begins with clarity about the syllabus.
Here’s what you must focus on:

Mathematics

General Ability Test (GAT)

Part A: English

• Grammar, Vocabulary, Synonyms, Antonyms, Comprehension

Part B: General Knowledge

Pro Tip: Start your preparation at least 8–10 months before the exam. Consistency and revision are your biggest assets.

Step 5: Physical Fitness & Personality Development

Clearing the NDA written exam is just half the battle — the SSB interview demands mental sharpness, leadership qualities, and physical endurance.

Tips for Physical Fitness

• Push-ups, pull-ups, sit-ups (minimum 30 each)

• Yoga and meditation for focus

• Balanced diet (avoid junk food)

For Personality Development

• Read books on defence forces (e.g., “India’s Wars” by Air Vice Marshal Arjun Subramaniam)

• Stay updated with national and international events

Step 6: Avoid These Common NDA Preparation Mistakes

1. Ignoring NCERT basics

2. Not following a proper time table

3. Over-reliance on coaching without self-study

4. Avoiding revision

5. Neglecting physical training

6. Underestimating English and Current Affairs

Remember: Coaching is a catalyst, but self-study is the foundation of success.
