Age: Candidates must be between 16.5 to 19.5 years old.
Education:

For Army Wing: 10+2 or equivalent from a recognized board.
For Navy & Air Force Wings: 10+2 with Physics and Mathematics.

Gender: Only male candidates (currently) can apply.

2. Selection Process:

Written Exam: It evaluates a candidate's expertise in topics such as Mathematics and General Ability (English, General Knowledge, Physics, Chemistry, Geography, History, Current Affairs, etc.).
SSB Interview: Candidates who pass the written examination then appear for the Services Selection Board (SSB) interview, which tests the physical and mental fitness, leadership qualities, etc.

3. Exam Structure: Please find exam structure for your reference purpose:

Written Test:

Paper	Subject	Duration	Questions	Max Marks	Negative Marking
01	Mathematics	2.5 hours	120 MCQs	300	-0.83 per wrong answer
02	General Ability Test (GAT)	2.5 hours	150 MCQs	600	-1.33 per wrong answer
–	SSB Interview	4-5 days	Psychological/Group Tasks	900	–

Important Features of the Exam:

Mathematics: Topics include Algebra, Trigonometry, Calculus, Probability, Geometry and more from Class 11–12 curriculum.
General Ability Test (GAT): Contains questions on English, Physics, Chemistry, Current Affairs, History, general Knowledge and Geography.
SSB Interview: This phase tests your leadership, teamwork and decision-making skills through psychological tests, group discussion and personal interview. It has 2 stages:

Stage 1: Screening (OIR Test & PPDT)

Stage 2: Psychological tests, group exercises and personal interview.

Knowing the exam pattern is the initial step in planning your NDA exam preparation. Subsequently, you can go deeper into resources such as last year papers, sample papers and mock tests to enhance your preparation.

After clearing the exam and SSB interview, candidates join National Defence Academy (NDA) for a 3-year training period. During this period, they receive military training and education. Upon successful completion, they are commissioned as officers in the Indian Armed Forces.

Previous Year Question Papers: Blueprint for Success

Previous years' question papers serve as priceless resources, providing you with a detailed insight into the patterns and trends of the exam. Analyzing these papers can help you recognize common topics, know how difficult the level is and familiarize yourself with the structure of questions.

How do historical exam papers help you in your NDA exam prep?

Spot Question Trends: Solving previous year papers can help you to identify the topics that are most frequently tested. For instance, in Mathematics section, questions pertaining to subjects such as Integral Calculus and Matrices tend to appear regularly, whereas in the General Ability Test (GAT), Defence Current Affairs questions often constitute a major part. Example: Mathematics paper usually contains approximately 8-10 Matrices questions annually.
Decoding Shifts in Difficulty: Previous year exam papers assist you in spotting fluctuations in question difficulty. For instance, you might notice that trigonometry problems have evolved over time with increasing complexity and application-based aspects. This allows you to prepare by studying aspects that may bring more challenges in the current year.
Adjustment to Marking Schemes: Working through old papers with the actual negative marking system in place will aid you in practicing the art of guessing intelligently and not resorting to making wild attempts.
SSB Interview Preparation: Historical information about the types of leadership and decision-making scenarios usually asked during the interview rounds can prepare you psychologically for this important phase.

Pro Tip: Try to solve 5-10 years of NDA question papers to gauge topic-wise weightage and recurring themes clearly. Revisit past exams and practice using a stopwatch within time limits, imitating real exam conditions.

Sample Papers: Your Simulation Lab for NDA Exam

Sample question papers are so made that they closely resemble the format and level of the real examination, with slight variations only. They not only test your comprehension of the subject matter but also your time management skills and capability to work under pressure.

Rewards of Practicing with Sample Papers

New Formats Exposure: Sample papers can have questions framed in new formats or hybrid questions. These are questions that combine elements from various subjects, such as using physics concepts to defence technologies. This will enable you to work on improving interdisciplinary thinking.
Self-Audit Tool: Trying to attempt sample papers can help you identify your weak spots. For instance, if you are not so good with Probability in Mathematics or English Comprehension in the GAT, you can spend additional time strengthening these areas according to your performance.
Flexibility Training: Sample papers often have surprise elements in them, like data interpretation problems in GAT. Such elements prepare you to be flexible with handling unexpected questions in the actual exam.
Writing Responses: Presentation of your solution, especially in Mathematics, is as crucial as the accuracy of your calculations. Sample papers provide an opportunity to practice writing clean, well-structured answers so that you can be clear in your response.

Pro Tip: Get your sample papers from authentic platforms like Physicswallah and Vedantu to ensure that questions are of good quality and relevant. Also, attempt topic-wise sample papers to focus on specific areas for improvement.

Mock Exams: Dress Rehearsal for NDA Exam

Mock Exams are designed to simulate the actual test environment, recreating real-world conditions such as time pressure and stress. They provide a complete practice experience, getting candidates mentally and physically prepared for the entire exam. Mock tests are designed to build your stamina and confidence required to perform under actual exam settings.

Real-Time Performance Monitoring: Mock tests provide instant feedback on your performance, enabling you to monitor your progress over multiple attempts. Comparing scores between mocks assist you to determine areas where you're lagging and require more effort.
Stress Inoculation: Attempting mock exams under strict time restrictions recreates the tension of the real exam scenario. This exposure will help in keeping you calm and composed when you sit for your NDA exam.
Strategy Optimization: With mock exams, you can plan to implement different exam strategies. For example, you can solve high-weightage sections first or omit difficult questions for easier ones to get the best possible score.
SSB Simulation: Apart from written mock exams, it's also useful to rehearse mock group interviews. Mock interviews help you develop your leadership skills, decision-making skills and communication skills - abilities that are essential in the SSB interview.

Pro Tip: Complete atleast 15-20 full-length mock exam sets prior to the actual exam. After every test, go through your answers carefully and correct your mistakes. This prevents you from repeating the same mistakes during the actual exam.
