NDA Previous Year Questions: Last 10 Years' Papers with Answers (2015, 2025)

If you have searched for NDA previous year questions and landed on five different websites, each offering only a fragment of what you actually need, you are not alone. Most aspirants spend more time hunting for papers than sitting down to practise them. This guide ends that search. Below you will find the exam pattern, a year-wise paper list, topic frequency data, difficulty trends, scoring benchmarks, and a four-step practice framework, all gathered in one place. The same principle applies to negative marking: 0.83 per wrong answer.

Roughly 4 lakh candidates register for the UPSC NDA NA exam every year, yet a large share never systematically work through past papers. That gap in preparation is exactly where most selections are won or lost, and it is especially true when it comes to NDA previous year questions.

NDA Exam Pattern at a Glance

The NDA written exam consists of two papers sat on the same day. Understanding the structure before touching a single past paper saves you from misreading your own scores later.

Paper I: Mathematics carries 300 marks and contains 120 questions. Each correct answer earns 2.5 marks. Wrong answers attract a negative marking of 0.83 marks per question. The allotted time is 150 minutes.

Paper II: General Ability Test (GAT) carries 600 marks and contains 150 questions. Each correct answer earns 4 marks, and the same negative marking of 0.83 marks per wrong answer applies. Time allowed is 150 minutes. The NDA exam pattern therefore adds up to 270 questions, 900 total marks, and 300 minutes of combined exam time across both sittings.

The GAT paper syllabus is divided into two parts. Part A covers English (200 marks) and Part B covers General Knowledge (400 marks), which includes Physics, Chemistry, General Science, History, Geography, and Current Events. This split matters a great deal when you start building your study priority list.

UPSC conducts NDA 1 and NDA 2 every year, typically in April and September. Each cycle follows the same paper structure and marking scheme. Sources including Testbook and Prepp confirm this consistent format across all recent cycles.

Collecting the papers is only the first step. The real work begins when you use them strategically, not just for practice but for pattern recognition.

Topic-Wise Frequency Analysis: What Repeats Most?

NDA topic wise weightage follows a visible pattern across NDA 1 and NDA 2 cycles from 2015 to 2025. Certain chapters appear in nearly every paper, making them non-negotiable for any serious aspirant.

Mathematics Paper: High-Frequency Chapters

• Trigonometry, trigonometry frequency in NDA papers is among the highest of any chapter. Expect 15 to 20 questions per paper covering heights and distances, identities, and inverse trigonometric functions.

• Matrices and Determinants, consistently producing 8 to 12 questions, often combining with linear equations.

• Statistics and Probability, appearing reliably with typically 8 to 10 questions per cycle.

• Algebra (complex numbers, quadratic equations, permutations), second only to trigonometry in raw question count.

• Differential Calculus and Integral Calculus, combined, these two account for roughly 20 questions per paper.

GAT Paper: High-Frequency Sections

• Physics, covering mechanics, optics, and electricity, and one of the heaviest scoring sections in General Knowledge.

• History, modern Indian history and the freedom struggle feature repeatedly across all years.

• Geography, physical and political geography of India alongside world geography basics.

• NDA English comprehension and grammar together form the entire 200-mark English section.

• NDA general awareness questions on current events tend to vary yearly, but science-based static GK remains stable.

This frequency data turns the Mathematics paper's 120 questions from an intimidating block into a manageable checklist. Prioritise the chapters above before spending time on lower-frequency topics like sets or linear programming.

Multi-Year Difficulty Trends and Scoring Benchmarks

A multi-year NDA difficulty level analysis across 2019 to 2025 shows a consistent pattern. Mathematics has stayed at a moderate difficulty level in most cycles, with occasional harder ratings when calculus and coordinate geometry questions are heavier. GAT generally rates as easy to moderate, with English holding at easy and Physics sometimes pushing into moderate territory.

NDA good attempts benchmarks by difficulty level:

• Easy paper: 90 to 100 attempts out of 120 in Maths; 120 to 130 out of 150 in GAT.

• Moderate paper: 75 to 90 in Maths; 110 to 120 in GAT.

• Difficult paper: 60 to 75 in Maths; 100 to 110 in GAT.

These attempt counts assume reasonable accuracy. Because of the negative marking of 0.83 per wrong answer, attempting 90 questions with 70 percent accuracy outperforms blindly attempting all 120.

On the NDA cutoff score for SSB call, aspirants frequently ask whether 325 marks is enough. Based on community data and published cutoffs, the general written-exam score needed to receive an SSB call-up has typically ranged between 306 and 360, varying by category and year. The SSB interview written score is separate from the merit score used for final selection, so crossing the written cutoff earns the SSB call but does not guarantee a recommendation. Scoring 800-plus in the written exam places you in a strong position entering SSB, but the interview carries substantial independent weight.

Tracking NDA answer key releases after each exam and calculating your predicted score before results are announced is a useful habit, one that trains you to evaluate your own accuracy honestly.

How to Use NDA Past Papers: A 4-Step Preparation Framework

Knowing how to prepare for NDA using past papers is a specific skill. Downloading the PDFs and reading through questions casually produces almost no improvement. The four-step loop below does.

Step 1: Diagnostic Attempt (No Timer)
Sit with a 2019 or 2021 paper and attempt every question without a clock running. The goal is not to score well; it is to identify which chapters feel unfamiliar. Mark every question you skipped or guessed. This diagnostic attempt reveals your genuine baseline before any NDA mock test pressure distorts your judgment.

Step 2: Timed Full Mock
Take a different year's paper under strict exam conditions: 150 minutes per paper, no breaks, phone off. Simulate the real test environment as closely as possible. Score yourself using the official marking scheme, 2.5 per correct answer in Maths and 4 per correct answer in GAT, minus 0.83 for each wrong answer.

Step 3: Build an Error Log by Topic
After the mock, categorise every wrong answer by chapter. A spreadsheet works well here. After three or four papers, patterns emerge. If you are losing marks repeatedly in Matrices or in Geography, that chapter earns the next block of revision time.

Step 4: Targeted Chapter Revision, Then Loop
Revise the flagged chapters using your standard study material, then return to Step 2 with a new paper. This loop is the entire framework. Each pass through it sharpens accuracy and reduces reliance on guessing.

NDA 2026 preparation benefits most from starting this loop at least four months before the exam, giving you time to complete six to eight full past-paper cycles.

Subject-Wise Important Questions from NDA Previous Years

Certain question types reappear so regularly that recognising them in advance gives you a measurable advantage. The examples below come from high-frequency topics confirmed across multiple years of past papers.

Mathematics: Trigonometry questions frequently ask you to simplify expressions involving sin, cos, and tan identities, or to find the value of an inverse trigonometric function within a given range. Matrices questions often combine with determinant properties and ask for the rank or solution of a system of linear equations.

Physics (GAT): Questions on Newton's laws, projectile motion, and simple harmonic motion appear in nearly every paper. Optics questions involving mirrors and lenses recur across NDA 1 and NDA 2 cycles.

History (GAT): The 1857 revolt, Montagu-Chelmsford Reforms, Non-Cooperation Movement, and India's independence timeline generate repeated questions. Modern Indian history up to 1947 is the most tested period.

Geography (GAT): Questions on river systems, monsoon patterns, soil types, and India's international boundaries appear consistently. Physical geography of India accounts for a significant share of the 400-mark General Knowledge section.

English (GAT): NDA English comprehension passages test vocabulary in context, inference, and author tone. Grammar questions focus on spotting errors, fill-in-the-blanks with prepositions, and sentence improvement. These question types have remained structurally identical across all years from 2015 to 2025.

FAQs

Can I find NDA previous year question papers with answers for the last 10 years in one place?

Yes. Platforms including Selfstudys and Oswaal host free NDA question paper PDF download collections covering 2009 to 2025. Testbook and Prepp offer year-wise and subject-wise filtered views. No single UPSC page consolidates all of them, but the sources linked in this guide together cover the full 10-year range with NDA answer key files included for most cycles.

Which topics repeat the most in NDA papers and how should I prioritise them?

In Mathematics, trigonometry, matrices, and statistics are the top three by question count. In GAT, Physics, History, Geography, and English comprehension dominate. Start with these before spending time on lower-frequency topics. The NDA topic wise weightage data above gives you the exact priority order.

How do I use NDA past papers to build an effective study strategy?

Follow the four-step loop: diagnostic attempt, timed mock, error log by chapter, and targeted revision. Repeat the cycle with a different year's paper each time. This method directly answers how to prepare for NDA using past papers by making each practice session corrective rather than just repetitive.

What is a good score in the NDA written exam to get an SSB call-up?

The NDA cutoff score for SSB call has ranged between approximately 306 and 360 marks out of 900 in recent years, depending on the cycle and category. Scoring above 360 keeps you comfortably above the cutoff in most years. Crossing the SSB interview written score threshold earns you the interview call, but the SSB itself is evaluated independently and carries its own merit weight.

How difficult is the NDA paper compared to Class 12 boards?

The NDA difficulty level sits above board exams in terms of speed and question variety, but the concepts do not go beyond the Class 12 syllabus. The primary difference is time pressure and the negative marking of 0.83, which punishes guessing. An aspirant who has completed Class 12 Maths and Physics thoroughly will find the content familiar; the exam tests application speed more than advanced knowledge.
