The NDA Exam Pattern 2027 explains how the National Defence Academy entrance examination is structured, including the number of questions, maximum marks, exam duration and negative marking. Conducted by the Union Public Service Commission (UPSC), the NDA written examination tests candidates in Mathematics and the General Ability Test (GAT).

The written examination carries 900 marks, followed by the Services Selection Board (SSB) Test/Interview, which carries another 900 marks under the standard selection scheme. Understanding the exam pattern helps aspirants plan their study schedule, practise time management and avoid losing marks through incorrect answers.
This guide covers the NDA 2027 paper structure, subject-wise marks, expected question counts, marking scheme, syllabus overview and preparation tips. Candidates should always check the applicable UPSC notification for the final rules for their examination cycle.

Negative marking is calculated as one-third of the marks assigned to the question for an incorrect answer. The figures above are rounded for readability. No penalty applies for leaving a question unanswered.
Example: How negative marking affects your score
Suppose you answer 80 Mathematics questions correctly and 20 incorrectly.
| Calculation | Marks |
|---|---|
| 80 correct × 2.5 | +200 |
| 20 incorrect × approximately 0.833 | ?16.67 |
| Net score | 183.33 |
This example illustrates why random guessing can reduce your score. Practise identifying questions you can solve confidently and learn when it is better to move on.
NDA Mathematics Paper Pattern 2027
The Mathematics paper carries 300 marks and has a duration of 2 hours and 30 minutes. It assesses mathematical concepts, numerical accuracy and problem-solving ability.
Major syllabus areas include:
Candidates should practise questions from every syllabus area. UPSC does not guarantee a fixed number of questions from each chapter, so chapter-wise question distributions found in unofficial analyses should be treated as estimates rather than official rules.

NDA GAT Paper Pattern 2027
The General Ability Test carries 600 marks and lasts 2 hours and 30 minutes. It is divided into English and General Knowledge.
| Section | Maximum marks | Standard question count |
|---|---|---|
| English | 200 | 50 |
| General Knowledge | 400 | 100 |
| Total GAT | 600 | 150 |
English section
The English section tests language understanding and practical use of words. Preparation areas include:
General Knowledge section
The General Knowledge section broadly covers:
The exact scope of the examination is defined in the official syllabus. Candidates should combine concept revision with regular practice questions and current-affairs preparation.
NDA Exam Duration and Time Management
Candidates receive 150 minutes for each written paper. Effective time management can help prevent unfinished questions and careless mistakes.

Suggested practice-time allocation
These are practice recommendations, not official section-wise time limits.
Mathematics
150 minutes Spend time on familiar questions first, then return to lengthy problems.
GAT
150 minutes Practise pacing across English and General Knowledge to avoid spending too long on one section.
Time-management tips
- Solve previous years’ question papers under timed conditions.
- Identify questions that can be answered quickly and accurately.
- Avoid spending excessive time on one difficult question.
- Practise mental calculations and formula recall for Mathematics.
- Review mock-test errors and adjust your approach.
- Follow the examination hall instructions and manage the time remaining.
NDA Written Exam vs SSB Interview
The written examination and SSB assessment serve different purposes in the selection process.
| Feature | Written examination | SSB Test/Interview |
|---|---|---|
| Purpose | Tests academic knowledge and aptitude | Assesses officer-like qualities and suitability |
| Assessment | Mathematics and GAT | Psychological, group, interview and related assessments |
| Marks | 900 | 900 |
| Format | Objective-type written papers | Multiple assessment methods |
| Main preparation | Syllabus, practice papers, accuracy | Communication, self-awareness, teamwork and reasoning |
A strong written score alone does not guarantee selection. Candidates must also qualify the SSB assessment, meet medical standards and satisfy the applicable eligibility, merit and vacancy requirements.
