NDA Exam Patterns
The National Defense Academy (NDA) exam is conducted by the Union Public Service Commission (UPSC) in two stages:
- Written Exam: The written exam consists of two papers, namely Mathematics and General Ability Test (GAT). The Mathematics paper is of 300 marks, while the GAT paper is of 600 marks. The total duration of the written exam is 5 hours (2.5 hours for each paper).
- SSB Interview: Candidates who qualify for the written exam are called for the Services Selection Board (SSB) interview. The SSB interview comprises two stages – Stage I and Stage II. Stage I includes Officer Intelligence Rating (OIR) tests and Picture Perception and Description Test (PPDT). Stage II includes Interview, Group Testing Officer Tasks, Psychology Tests, and the Conference.
The final selection of the candidates is based on their performance in the written exam and the SSB interview.
Here are some important points to note about the NDA exam pattern:
- The written exam is objective in nature and is conducted in offline mode.
- Both Mathematics and GAT papers are of 2.5 hours each and are conducted on the same day.
- The GAT paper tests the candidates’ knowledge of English, General Knowledge, Physics, Chemistry, General Science, Geography, and Current Events.
- There is negative marking in the written exam, where 1/3rd of the marks are deducted for every incorrect answer.
- The SSB interview is conducted for 5 days and comprises various psychological and physical tests to assess the candidates’ suitability for a career in the Armed Forces.
- The final selection of the candidates is based on their overall performance in the written exam and the SSB interview.
