In this detailed guide, we’ll explain how to prepare effectively for the NDA 2026 Written Exam and SSB Interview, and how Doon Defence Academy (DDA) — through its offline and online courses — can help you achieve your dream of joining the Indian Army, Navy, or Air Force.

Understanding the NDA Exam and SSB Process

Before starting your preparation journey, it’s crucial to understand the structure and selection process.

NDA Written Exam Structure

The UPSC NDA written exam consists of two papers:

Mathematics – 300 Marks
General Ability Test (GAT) – 600 Marks

Both papers are objective type with negative marking.
The GAT paper covers English, Physics, Chemistry, General Science, History, Geography, and Current Affairs.

SSB Interview Overview

Candidates who clear the written exam are called for the Services Selection Board (SSB) Interview. The SSB is designed to assess Officer-Like Qualities (OLQs) such as leadership, communication, teamwork, and confidence through a 5-day evaluation process that includes:

Screening Tests (OIR, PP&DT)
Psychological Tests (TAT, WAT, SRT, SD)
GTO Tasks (Group Discussions, Planning Exercises, Physical Tasks)
Personal Interview

How to Prepare for NDA 2026 Written Exam

Cracking the NDA written exam requires conceptual clarity, regular practice, and time management. Here’s how you can prepare effectively:

1. Start Early and Stay Consistent

Begin your NDA 2026 preparation at least 12 months in advance. If you’re in Class 11 or 12, this is the right time to strengthen your fundamentals. Create a realistic study schedule and stick to it daily.

2. Subject-Wise Preparation Strategy

Mathematics

Study NCERTs (Classes 9–12) to build a strong base.
Practice important topics like Algebra, Trigonometry, Calculus, and Geometry regularly.
Solve previous years’ NDA question papers to understand question patterns.

English

Focus on improving vocabulary and grammar.
Read newspapers and editorials daily for comprehension and current affairs.
Practice synonyms, antonyms, spotting errors, and cloze tests.

General Ability / GK / Science

Revise NCERT Science (Classes 6–10) for basic concepts.
Follow national and international current events.
Maintain short notes for quick revision.

3. Attempt Weekly Mock Tests

Practice is the key! Take weekly mock tests to check your preparation level.
At Doon Defence Academy, students undergo regular mock tests and analysis sessions to identify weak areas and track progress.

4. Revise Smartly

Divide your revision time into three parts:

Formulas and key concepts
Quick practice sets
Mixed question-solving sessions
Use flashcards and mind maps for better recall.

How to Prepare for the SSB Interview

Clearing the written exam is just the first step. The SSB Interview is where your personality, attitude, and leadership potential truly matter.

1. Understand What the SSB Looks For

The SSB evaluates candidates on 15 Officer-Like Qualities (OLQs) — such as initiative, confidence, decision-making, and teamwork.
Be genuine, confident, and self-aware — don’t try to fake answers.

2. Prepare for Each Stage of SSB

Screening Tests (OIR, PP&DT)

Practice verbal and non-verbal reasoning regularly.
Work on story narration and group discussion skills.

Psychological Tests (TAT, WAT, SRT, SD)

Be spontaneous and honest in your answers.
Avoid memorized responses — think practically.
Develop self-awareness by reflecting on your thoughts and actions.

GTO Tasks

Build physical stamina and team spirit.
Learn to express logical solutions during group planning exercises.
Participate in group discussions and outdoor activities.

Personal Interview

Be truthful about your academics, hobbies, and background.
Stay updated on defence news and current affairs.
Maintain positive body language and good communication.

3. Focus on Physical & Mental Fitness
