Understanding the NDA Exam
The NDA examination is conducted twice a year by UPSC. The selection process consists of three stages:
- Written Examination
- SSB Interview (5-day selection process)
- Medical Examination
The written exam includes two papers: Mathematics and the General Ability Test (GAT). Mathematics tests logical thinking and numerical ability, while GAT evaluates English proficiency, general knowledge, science, and current affairs. Clearing the written exam is the first and most crucial step toward becoming an officer.
