What is NDA Exam?
The pursuit of a commission in the Indian Armed Forces begins with a fundamental question: what is NDA exam? It is a national-level competitive test conducted twice a year by the Union Public Service Commission (UPSC). The NDA full form—National Defence Academy—represents a unique “Cradle of Military Leadership,” where young cadets from different backgrounds are forged into officers.
The National Defence Academy and Naval Academy Examination is distinct because it selects candidates for both the tri-service academy in Pune and the specialized naval training hub in Kerala. Whether you are searching for the NDA application form or the latest UPSC NDA exam result, understanding the dual nature of this entry is critical.
What is Naval Academy?
A common point of confusion among students is the difference between the two primary institutions. To understand what is naval academy, one must look at the Indian Naval Academy (INA) at Ezhimala.
Naval Academy Means Technical Excellence
While the NDA offers a joint-service environment, naval academy means an exclusive focus on maritime warfare. Candidates who enter the Indian Naval Academy via the naval academy exam (10+2 Cadet Entry) are enrolled in a 4-year B.Tech program. This is a technical path compared to the 3-year BA/BSc/BTech degrees offered at Khadakwasla. Ensuring you meet the Indian Naval Academy eligibility is vital, as it requires a strong foundation in Physics and Mathematics.

Mastering the NDA Exam Pattern and Syllabus
The NDA exam pattern is designed to test both mental speed and academic depth. It consists of two objective papers.
Paper I: Mathematics (300 Marks)
The NDA syllabus for Math includes 120 questions. To clear the 25% sectional cutoff, you must master:
-
Calculus & Algebra: The pillars of the paper.
-
Trigonometry: Direct applications in navigation and physics.
-
Statistics & Probability: High-scoring sections for data interpretation.
Paper II: General Ability Test (GAT) (600 Marks)
The NDA exam syllabus for GAT is divided into:
-
English (200 Marks): Tests grammar, vocabulary, and comprehension.
-
General Knowledge (400 Marks): Covers Physics, Chemistry, History, Geography, and Current Events.
High-Score Strategy: Topic-Wise Weightage Breakdown
Analysis of the last 10 years of NDA previous year question paper trends reveals a consistent pattern. In both the National Defence Academy and Naval Academy examination papers, UPSC leans heavily on specific “core” chapters.
Paper I: Mathematics Weightage (300 Marks)
With 120 questions and only 150 minutes, you have roughly 75 seconds per question. Mastery of the following chapters covers nearly 60% of the paper:
| High-Priority Chapter | Avg. No. of Questions | Marks (Approx) | Why It Matters |
| Algebra | 25–30 | 65–75 | Foundational for every other topic. |
| Trigonometry | 18–22 | 45–55 | Direct questions on identities and heights. |
| Calculus | 20–25 | 50–60 | High marks but requires conceptual depth. |
| Analytical Geometry | 15–20 | 40–50 | 2D and 3D concepts are recurring favorites. |
| Statistics & Probability | 10–12 | 25–30 | Scoring, provided you know the formulas. |
| Matrices & Det. | 8–10 | 20–25 | Easiest marks to secure with speed tricks. |
Paper II: GAT Weightage (600 Marks)
The NDA exam syllabus for GAT is the “Rank Booster.” While English is fixed at 50 questions, the General Knowledge (100 questions) is weighted as follows:
-
Physics (25%): Focus on Mechanics, Optics, and Electricity.
-
Geography (20%): Indian and Physical Geography are high-yield.
-
History (20%): 70% of this section is the Indian Freedom Movement.
-
Chemistry (15%): Focus on everyday chemical reactions and atomic structure.
