The National Defence Academy (NDA) is a prestigious institution in India that provides training for cadets who aspire to join the Indian Army, Navy, and Air Force. It is known for its rigorous training and high standards of discipline. The NDA exam is a highly competitive exam that requires extensive preparation. Therefore, candidates should know what is NDA and must have knowledge of the NDA exam pattern and NDA syllabus 2023.
The NDA exam is conducted every year by the Union Public Service Commission (UPSC). It is one of the most competitive exams in the country, and only a few deserving candidates are selected based on their performance. In this article, we will discuss what is NDA, the NDA syllabus 2023, the exam pattern, and NDA exam eligibility.
The National Defence Academy Exam (NDA) is a written exam taken by candidates who wish to join the National Defence Academy (NDA), an institution that trains cadets for the Indian Armed Forces. The NDA exam is the national-level exam conducted by the UPSC twice a year, i.e., in April and September.
The selection process for the NDA includes the following stages:
The written test includes Mathematics and General Ability Test (GAT) sections, and the Services Selection Board (SSB) interview includes physical tests, psychological tests, and an interview.
Check the NDA exam pattern 2023 in the following table:
| Paper | Exam Duration | Maximum Marks |
|---|---|---|
| Paper I- Mathematics | 2.5 Hours | 300 Marks |
| Paper II- General Ability Test (GAT) | 2.5 Hours | 600 Marks |
| Total | 5 Hours | 900 Marks |
To crack the NDA exam, it is essential to have a thorough understanding of the NDA syllabus. In this section, we have provided a detailed breakdown of the NDA syllabus 2023.
The NDA syllabus is divided into two parts: Mathematics and General Ability Test (GAT). Check the NDA syllabus 2023 below:
