National Defence Academy (NDA) is the Joint Services academy of the Indian Armed Forces. The Union Public Service Commission (UPSC) conducts the NDA Exam twice a year as a national-level exam. Male candidates typically seek this highly desirable defence job, and selection is based on a written test followed by a Personality Test. The NDA written examination consists of two papers: Mathematics and General Ability Test (GAT). Aspiring applicants, both male and female, should refer to the detailed NDA Syllabus 2023 outlined in this article to begin their exam preparation.
