NDA Maths Syllabus 2026: Important Topics & Chapter-wise Weightage

Mathematics is more than just a subject in the National Defence Academy (NDA) entrance exam; it is the fundamental gatekeeper. With the NDA 1 2026 exam scheduled for April 12, 2026, and NDA 2 2026 set for September 13, 2026, students must align their preparation with the latest academic trends. The 2026 paper follows a rigorous 300-mark structure, where precision and speed are paramount.

In this guide, we break down the NDA Maths Syllabus 2026 focusing on course-specific depth and stream-wise importance. Whether you are coming from a pure Science stream or exploring integrated technical courses, understanding the weightage of each chapter is the first step toward clearing the sectional cutoff and securing your place in the 157th and 158th NDA Courses.

NDA Maths Syllabus 2026: Course Overview & Structure

The Mathematics paper in 2026 consists of 120 Multiple Choice Questions (MCQs) to be solved in 150 minutes. The syllabus is primarily based on the 10+2 curriculum (Class 11 and 12), but the application of these concepts is designed to test technical aptitude.

Exam Marking Scheme 2026

• Total Marks: 300

• Number of Questions: 120

• Marks per Correct Answer: +2.5

• Negative Marking: -0.83

• Sectional Cutoff: 25% (Minimum 75 Marks)

Pro-Tip for Aspirants: While the written exam is the first hurdle, students often explore diverse scientific fields.

Chapter-wise Weightage in NDA Maths Syllabus 2026

The 2026 trends indicate a continued reliance on core analytical chapters. To optimize your study hours, focus on the following high-weightage sections of the NDA Maths Syllabus 2026:

1. Algebra (Approx. 30-35 Questions)

Algebra remains the powerhouse of the NDA paper. It covers a wide range of topics that are essential for both the Army and Air Force/Navy technical entries.

• Sets, Relations, and Functions: Essential for logical reasoning.

• Complex Numbers: Focus on properties and the cube roots of unity.

• Quadratic Equations: Formulation and nature of roots.

• Sequence & Series: AP, GP, and HP variations.

• Permutations & Combinations (P&C): Often integrated with Probability.

2. Trigonometry (Approx. 20-22 Questions)

Trigonometry is highly scoring if you have mastered the identities.

• Trigonometric Ratios & Identities: The foundation for 15% of the paper.

• Inverse Trigonometry: Frequently tested in conjunction with Calculus.

• Properties of Triangles: Focus on Sine and Cosine rules.

3. Differential & Integral Calculus (Approx. 20-25 Questions)

Calculus is the "make or break" section for many students. In 2026, expect a mix of direct formula-based questions and multi-step applications.

• Limits, Continuity, and Differentiability.

• Differentiation: Chain rule and second-order derivatives.

• Integration: Substitution methods and Definite Integrals (Area under curves).

• Differential Equations: Solving first-order equations.

Detailed Topic Breakdown & Data Trends for 2026

The UPSC has refined the 2026 syllabus to ensure it matches the technical demands of modern defense technology. Below is the refined topic breakdown:

Section	Key Topics to Master	Expected Questions
Analytical Geometry	Straight Lines, Circles, Parabola, Ellipse, Hyperbola	18 - 20
Matrices & Determinants	Types of Matrices, Adjoint/Inverse, Cramer’s Rule	10 - 12
Vector Algebra	Dot Product, Cross Product, Scalar Triple Product	8 - 10
Statistics & Probability	Mean/Median/Mode, Bayes' Theorem, Binomial Distribution	12 - 15

Expert Preparation Tips for NDA 1 & 2 2026

1. NCERT is Non-Negotiable: Approximately 85% of the concepts in the NDA Maths Syllabus 2026 are traced directly back to Class 11 and 12 NCERT textbooks.

2. Time Management: You have roughly 75 seconds per question. Practice solving 50 questions daily in a timed environment to build muscle memory.

3. The "Elimination" Technique: In the 2026 paper, many Trigonometry and Algebra questions can be solved by substituting options.

4. Focus on Formulas: Create a "Formula Sheet" for 3D Geometry and Vector Algebra. These chapters are formula-intensive but theoretically light.

Explore Other Streams: If you find that technical research and field science appeal to you, you may want to compare your options. Discover the Top B.Sc Agriculture Colleges in India 2026 to see how various academic streams stack up.

FAQs on NDA Maths Syllabus 2026

Q1: What is the most important chapter in the NDA Maths Syllabus 2026? 

Algebra and Trigonometry collectively cover nearly 50% of the paper. Specifically, focus on Sets, Quadratic Equations, and Trigonometric Identities for maximum marks.

Q2: Is there a change in the NDA Maths pattern for the year 2026? 

The fundamental pattern remains 120 questions for 300 marks. However, the 2026 papers show a slight increase in multi-concept questions (e.g., combining Calculus with Vectors).

Q3: Can a student from a non-maths background clear the NDA 2026 exam?  

It is challenging but possible. Since the NDA Maths Syllabus 2026 is based on Class 11-12 levels, a non-maths student must dedicate at least 4-5 months to mastering the basics.

Q4: How many marks are needed to clear the Maths sectional cutoff in 2026? 

Historically, the cutoff is 25%. For a 300-mark paper, you need at least 75 marks, though aiming for 120+ is recommended for a better merit rank.

Conclusion

Mastering the NDA Maths Syllabus 2026 requires a strategic shift from "studying everything" to "studying what matters." By prioritizing Algebra, Calculus, and Trigonometry, you can secure the necessary marks to move on to the SSB Interview. Remember, the journey to becoming an officer starts with a strong academic foundation.
