In the first stage of the interview, the candidates will face two rounds of the test. In the first round, they will be tested for Officer Intelligence Rating (OIR), and the Picture Perception and Description Test will be carried in the second round.
In the second stage, the candidates will undergo the Officer Group Task Test, Psychological Test and the Conference.

Exam Preparation Tips
Here are some tips that candidates can follow for the NDA & NA exam preparation:
- Know the Syllabus and Exam Pattern. Understanding the pattern and syllabus will help in making the study plan.
- Make a smart study plan. A smart study plan is one which have time allocated for all the subjects, breaks of 10-15 minutes between each study session, and most importantly which can be followed daily.
- Clear all your basics before practising any topic. If the basics are clear, you can solve even the complex questions.
- Solve Previous Years’ Question Papers. This is the most important thing while preparing for the exam. The previous years’ question papers give good ideas about the exam pattern, type of questions, difficulty level, etc.
- Do take out time for revision. Revision is important for getting hold on the topics. While studying, make notes of important points which will help in revision. Also, a week or two before the exam, focus on revision and solving sample papers.
We advise to strictly follow the syllabus. It is provided in the official notification. Do not waste your time in covering irrelevant topics.
