NDA exam is conducted for admission to the National Defence Academy and Indian Naval Academy. The written examination consists of two papers, Maths and General Ability Test (GAT). The Maths paper is based on topics studied from Classes 9 to 12 and features questions of a moderate difficulty level.
Mathematics plays a crucial role in NDA selection as it carries 300 marks out of the total score. A strong grip on high-weightage chapters can significantly improve a candidate’s chances of qualifying NDA 2026.
NDA Maths Exam Pattern and Marks Distribution
The NDA Maths paper includes a total of 120 objective-type questions. Each correct answer carries marks, while negative marking applies for incorrect responses. The duration of the Maths paper is 2.5 hours, and candidates must secure at least 25 percent marks to qualify.
Algebra, Calculus, and Trigonometry together account for nearly 60 percent of the paper, making them the most scoring areas in the NDA Maths section.
NDA Maths 2026 Chapter-Wise Weightage
Understanding chapter-wise weightage helps candidates prioritise preparation. Based on previous exam trends, the major weightage distribution is outlined below.
The NDA Maths paper broadly covers:
- Algebra and Vector Algebra: Around 25–30 percent
- Trigonometry: Around 20–25 percent
- Calculus: Around 20–25 percent
- Analytical Geometry: Around 10–15 percent
- Matrices and Determinants: Around 15–20 percent
- Statistics and Probability: Around 5–10 percent
Focusing on these areas can help candidates manage time efficiently during preparation.
NDA Maths Important Topics for NDA 2026
The most important topics for NDA Maths are identified through analysis of previous years’ question papers. Candidates should ensure complete coverage of the following areas. Key topics include:
- Algebra: Quadratic equations, polynomials, factorisation, sets, relations, functions, and simultaneous equations
- Matrices and Determinants: Matrix operations, determinants, and solving linear equations
- Trigonometry: Trigonometric ratios, identities, heights and distances, and applications in triangles
- Analytical Geometry: Equations of lines, circles, conic sections, and 3D geometry
- Calculus: Limits, continuity, differentiation, integration, and their applications
- Vector Algebra: Vector operations, dot and cross products, and applications
- Statistics and Probability: Mean, median, mode, probability, permutations, and combinations
These topics are frequently repeated and contribute heavily to the overall score.
NDA Maths Topic-Wise Weightage Based on PYQs
Analysis of previous year questions shows higher weightage for topics such as Matrices and Determinants, Differentiation, Sets and Functions, Quadratic Equations, Vectors, Probability, and Integration. Candidates are advised to practise numerical problems from these sections regularly.
How to Prepare for NDA Maths Section?
A focused and structured approach is essential for NDA Maths preparation. Candidates should begin by understanding the complete syllabus and exam pattern. Effective preparation strategies include:
- Covering the NDA Maths syllabus thoroughly
- Solving previous years’ question papers
- Practising mock tests regularly
- Revising formulas and concepts consistently
- Maintaining accuracy and speed during practice
With disciplined preparation and emphasis on high-weightage chapters, candidates can score well in the NDA Maths paper for the NDA 2026 examination.
