NDA Examination Syllabus: 2018 Breakdown

The National Defence Academy (NDA) examination is a prestigious gateway for candidates aspiring to join the Indian Armed Forces. The 2018 examination followed the standard format prescribed by the Union Public Service Commission (UPSC). Understanding this syllabus is crucial for candidates analyzing past patterns and preparing for future defense entrance assessments.

Structure of the Examination

The NDA 2018 written exam consisted of two main papers: Mathematics and the General Ability Test (GAT). Both papers were objective in nature.

Paper I: Mathematics

The Mathematics paper was designed to test the candidate's mathematical aptitude up to the 10+2 level. The syllabus included:

• Algebra: Concepts of sets, operations on sets, Venn diagrams, De Morgan laws, Cartesian product, relation, equivalence relation. Real numbers, complex numbers, modulus, argument, cube roots of unity, binary system, arithmetic, geometric and harmonic progressions.
• Matrices and Determinants: Types of matrices, operations on matrices, determinant of a matrix, basic properties of determinants, adjoint and inverse of a square matrix.
• Trigonometry: Angles and their measures, trigonometric ratios, trigonometric identities, properties of triangles, inverse trigonometric functions.
• Analytical Geometry of Two and Three Dimensions: Rectangular Cartesian coordinate system, distance formula, equations of lines, circles, conics, and coordinate geometry of three dimensions (distance, sections, direction cosines).
• Differential Calculus: Concepts of real-valued functions, domain, range, continuity, derivatives, geometrical interpretation, and application of derivatives in rate of change and optimization.
• Integral Calculus and Differential Equations: Integration as inverse of differentiation, method of substitution, standard integrals, definite integrals, and formation of differential equations.
• Vector Algebra: Vectors in two and three dimensions, magnitude and direction, scalar and vector products.
• Statistics and Probability: Classification of data, frequency distribution, cumulative frequency, mean, median, mode, outcomes, sample space, and basic probability theory.

Paper II: General Ability Test (GAT)

The GAT was divided into two distinct parts: English and General Knowledge.

Part A: English

The English syllabus was aimed at testing the candidate's understanding of English and workmanlike use of words. The topics covered included:

• Grammar and usage
• Vocabulary and synonyms/antonyms
• Comprehension and cohesion in extended text
• Spotting errors and sentence improvement

Part B: General Knowledge

This section was broad and evaluated the candidate's knowledge regarding various events and scientific phenomena. The syllabus included:

• Physics: Physical properties and states of matter, motion, force, work, energy, sound, electricity, and magnetism.
• Chemistry: Physical and chemical changes, elements, mixtures, compounds, laws of chemical combination, and properties of air and water.
• General Science: Basic knowledge of life sciences, human body, common epidemics, and significant discoveries.
• History: Freedom movement in India, major events of world history, and Indias cultural heritage.
• Geography: Physical features of the earth, climate, vegetation, major industries, and minerals.
• Current Events: Knowledge of important national and international events, prominent personalities, and cultural activities.

Conclusion

The 2018 NDA syllabus demanded a holistic approach from candidates, requiring equal proficiency in technical subjects like Mathematics and analytical subjects like General Knowledge. Success in the exam relied on a deep understanding of core concepts and constant awareness of current affairs, a pattern that continues to be relevant for all defense aspirants.
