What is the NDA Exam?
What is the NDA exam?
NDA stands for National Defence Academy.
The NDA examination is conducted by the Union Public Service Commission (UPSC) for admission to the National Defence Academy and Naval Academy under the notified schemes.
Through NDA, eligible candidates can pursue training for the Army, Navy and Air Force.
For many students, NDA is attractive because it provides an opportunity to begin the journey towards becoming an officer in the Armed Forces soon after Class 12.
How Many Times Is the NDA Exam Conducted in a Year?
The NDA & NA examination is generally conducted twice a year by UPSC.
The two examinations are commonly known as the following:
- NDA & NA Examination (I)
- NDA & NA Examination (II)
For example, UPSC’s 2026 examination calendar scheduled the NDA & NA Examination (I) for 12 April 2026, while the NDA & NA Examination (II) was scheduled for 13 September 2026.
Therefore, NDA aspirants generally get two opportunities every year to appear for the examination.
NDA Exam 2026 Important Dates
For NDA & NA Examination (II), 2026, the UPSC notified the following dates:
| Event | Date |
|---|---|
| Notification | 20 May 2026 |
| Last Date to Apply | 11 June 2026 |
| Examination Date | 13 September 2026 |

NDA Eligibility Criteria 2026
Before filling out the NDA application form, candidates should carefully check the eligibility criteria.
The major requirements include:
- Age
- Educational qualification
- Marital status
- Nationality
- Physical and medical fitness
Let’s understand each requirement.
NDA Age Limit
The exact age requirement is specified in every UPSC notification.
For NDA & NA Examination (II), 2026, eligible candidates were those born not earlier than 1 January 2008 and not later than 1 January 2011, subject to the conditions mentioned in the official notification.
Therefore, candidates should not rely only on a general statement such as “17 to 19 years”.

Candidates appearing in Class 12 can also apply, subject to the conditions in the notification.
Navy and Air Force Wings
For the Naval Wing and Air Force Wing, candidates must have passed or be appearing in Class 12 with the following:
Physics + Chemistry + Mathematics (PCM)
as subjects.
This distinction is very important.
In simple words:
Army: 12th pass/appearing
Navy: 12th with Physics, Chemistry and Mathematics
Air Force: 12th with Physics, Chemistry and Mathematics
Students studying in Class 11 are not eligible for the NDA examination.
NDA Application Fee 2026

How to Prepare for NDA Exam 2026: Step-by-Step Strategy
Now comes the most important question:
How should you prepare for NDA?
A good preparation strategy should combine academic preparation, question practice, current affairs, mock tests, physical fitness and SSB preparation.
Step 1: Understand the Complete Syllabus
Don’t start preparation randomly.
Download the latest NDA syllabus and divide it into subjects and chapters.
Make three categories:
Strong Topics
Average Topics
Weak Topics
Start by strengthening your weak areas while continuing regular revision of your strong subjects.
Step 2: Build a Strong Mathematics Foundation
Mathematics is a high-value component of the NDA examination.
Don’t try to memorise formulas without understanding them.
Follow this approach:
Concept โ Formula โ Example โ Practice โ PYQ โ Mock Test
Start with basic concepts and gradually move towards more difficult questions.
Step 3: Practise Mathematics Every Day
Mathematics requires regular practice.
Depending on your overall study schedule, try to devote around 1.5โ2 hours daily to mathematics.
Focus on:
- Speed
- Accuracy
- Short methods
- Formula revision
- Previous year’s questions
Don’t spend all your time reading solutions.
Solve questions yourself.
Step 4: Improve English Daily
English should not be studied only once or twice a week.
Spend some time every day on:
- Grammar
- Vocabulary
- Reading
- Comprehension
- Practice questions
Create a small vocabulary notebook.
Whenever you encounter an unfamiliar word, note:
Word โ Meaning โ Synonym โ Antonym โ Example sentence
Regular revision is more important than collecting hundreds of new words.
Step 5: Prepare General Knowledge Systematically
Divide GK into three sections:
Static GK
History, Geography, Polity, Science and other fundamental topics.
Current Affairs
National and international developments.
Defence Awareness
Important defence exercises, commands, ranks, equipment, organisations and major developments related to India’s Armed Forces.
Don’t try to memorise everything appearing in the news.
Focus on information that is relevant to the examination.
Step 6: Solve Previous Year Question Papers
Previous year questions are extremely valuable.
They help you understand:
- Question pattern
- Difficulty level
- Important topics
- Repeated concepts
- Time pressure
- Your weak areas
Don’t simply read the answers.
Set a timer and solve the paper like a real examination.
After completing it, analyse every mistake.
Step 7: Take Mock Tests
Mock tests are essential for improving examination performance.
After every mock test, maintain an error record.
For example:
| Area | Problem |
|---|---|
| Mathematics | Calculation errors |
| English | Vocabulary |
| Physics | Conceptual mistakes |
| GK | Lack of revision |
| Time | Too much time on difficult questions |
Over time, you will see exactly where your preparation needs improvement.
Step 8: Start SSB Preparation Early
One of the biggest mistakes NDA aspirants make is waiting until the written examination result before thinking about SSB.
Start developing the required skills from the beginning.
Work on:
- Communication skills
- Confidence
- Leadership
- Teamwork
- Decision-making
- General awareness
- Problem-solving
- Physical fitness
You don’t need to pretend to be someone else for SSB.
Instead, work on becoming a confident, disciplined and responsible version of yourself.
Step 9: Focus on Physical Fitness
NDA is not only an academic examination.
Physical and medical fitness are important components of the selection process.
Make exercise part of your daily routine.
You can include activities such as the following:
- Running
- Jogging
- Push-ups
- Squats
- Stretching
- Basic strength exercises
Start gradually and follow a consistent routine rather than suddenly doing intense workouts.
NDA Daily Study Timetable
A sample timetable could look like this:
| Time | Activity |
|---|---|
| Morning | Physical Exercise |
| 7:00โ9:00 AM | Mathematics |
| 10:00โ11:00 AM | English |
| Afternoon | Physics/Chemistry/Science |
| Evening | History/Geography/Polity |
| Evening | Current Affairs |
| Night | PYQ/Mock Test Analysis |
You don’t have to copy this timetable exactly.
The best timetable is one that you can follow consistently.
90-Day NDA Preparation Strategy
If you have around three months, divide your preparation into three phases.
Phase 1: First 30 Days โ Build Concepts
Focus on:
- Mathematics fundamentals
- English grammar
- Basic Physics and Chemistry
- History
- Geography
- Polity
- Basic current affairs
Phase 2: Days 31โ60 โ Intensive Practice
Focus on:
- Previous year papers
- Chapter-wise questions
- Mathematics speed
- GAT practice
- English practice
- Current affairs revision
Phase 3: Days 61โ90 โ Mock Tests and Revision
Focus mainly on:
- Full-length mock tests
- Revision
- Error analysis
- Weak topics
- Time management
- Formula revision
- Current affairs
This approach prevents you from spending the entire preparation period only studying theory.
Common Mistakes NDA Aspirants Should Avoid
1. Studying Without a Plan
Random preparation wastes time.
2. Ignoring Mathematics
Mathematics requires consistent practice.
3. Ignoring Current Affairs
Current events are part of the GAT syllabus.
4. Guessing Too Many Questions
Remember the negative marking.
5. Solving Mock Tests Without Analysis
A mock test is useful only when you learn from your mistakes.
6. Starting SSB Preparation Too Late
Personality development takes time.
7. Ignoring Physical Fitness
Medical and physical standards are important in the selection process.
8. Studying Too Many Books
A limited number of good resources, thoroughly revised, is generally better than collecting dozens of books.
