UPSC (Union Public Service Commission) conducts the National Defence Academy & National Naval Academy Examination (NDA & NA Examination) twice a year. It is a nationallevel exam for recruiting the candidates in Army, Navy, and Air force.
In a year it is conducted as NDA & NA (I), and NDA & NA (II) Examinations. The exam consists of 2 Papers (1) Mathematics and (2) General Ability Test (GAT). The syllabus of both papers is based on CBSE 10+2 standards. After qualifying for the written test the candidates are called for an NDA SSB Interview. And hence the final selection of Students depends on their performance in the written exam and SSB Interview.
Check Daily quizzes, attempt Mock tests, and watch Daily current affairs to improve your knowledge for competitive exams.
