UPSC NDA & NA (II) Mock Tests & Practice Papers

NDA I and NDA II are the same exam conducted twice a year by UPSC — NDA I typically in April and NDA II in September. The exam pattern, syllabus, and selection process are identical. The only difference is the intake batch: NDA I for January admission and NDA II for July admission to the National Defence Academy.

Yes, candidates can appear for both NDA I and NDA II in the same year, provided they meet the age criteria for both attempts. This doubles your chances of selection. Many successful candidates attempt both exams and clear through either one.

NDA II syllabus is the same as NDA I. Paper 1 (Mathematics) covers Algebra, Matrices, Trigonometry, Analytical Geometry, Differential Calculus, Integral Calculus, and Statistics. Paper 2 (GAT) covers English, Physics, Chemistry, General Science, History, Geography, and Current Affairs.

NDA II typically has 400 vacancies split across Army (208), Navy (42), Air Force (120), and Naval Academy (30). The exact numbers vary each year. The competition ratio is roughly 1:300 to 1:400, making it essential to prepare thoroughly for both the written exam and SSB interview.

Candidates must be physically fit with no medical conditions. Minimum height is 157 cm for Army, 162.5 cm for Air Force, and 157 cm for Navy. Vision standards vary by wing — Air Force has the strictest requirements (6/6 in each eye without glasses). Candidates undergo a thorough medical examination after clearing the SSB interview.

The SSB interview carries 900 marks — equal to the written exam. It is a 5-day process testing your Officer Like Qualities (OLQs) through psychological tests, group tasks, and personal interview. Many candidates who clear the written exam fail at SSB, so dedicated SSB preparation is crucial for final selection.

After NDA training and commissioning, officers serve in the Indian Army, Navy, or Air Force with opportunities for specialization, foreign postings, and higher studies. Career progression goes from Lieutenant to General/Admiral/Air Chief Marshal. Officers also get benefits like housing, medical care, canteen facilities, and post-retirement pension.
