Scoring well on the NDA written exam isn’t just about what you know – it’s also about how you attempt the paper. With 900 marks at stake and a strict negative marking system (–⅓ for each wrong answer), a well-crafted strategy can make or break your outcome. Let’s dive into 10 smart techniques to help you conquer both Mathematics (300 marks) and GAT (600 marks) with confidence.
1. Know the Exam Structure Inside Out
- Two sections: Mathematics (120 Qs, 300 marks) and General Ability Test (GAT, 150 Qs, 600 marks). Negative marking: –0.83 for Math, –1.33 for GAT wrong answers.
- Time limit: 2½ hours per section – you must balance speed and accuracy every step of the way.
2. Prioritise Easy Questions First
Start any section by quickly scanning and solving easy questions. This builds momentum, secures quick marks, and boosts confidence. Leave difficult questions for later once you’ve nailed the easy ones
3. Master Time Management
- Divide your 150 minutes:
- Mathematics: ~2.5 min/Q
- GAT: ~1 min/Q
- Monitor your pace and skip questions that take longer than expected. Circle them and return later if time permits

4. Use the Elimination Technique
Eliminate clearly wrong options to improve your odds when guessing. Even narrowing down to two options significantly raises your chances of getting it right.
5. Avoid Blind Guessing
If you have zero clue about a question, it’s better to leave it blank. Random guessing invites negative marks- steer clear unless you can make an educated guess.
6. Apply “Calculated Guessing”
When narrowed down to a couple of plausible choices, go ahead and take the educated guess. It’s a smart risk worth taking when it counts.

7. Adopt Block Guessing (Advanced Strategy)
Group 3–4 doubtful questions together and attempt them as a block. Statistically, this helps turn some guesses into gains with limited downside – used judiciously, it can boost your score over time
8. Practice Full-Length Mock Tests
Simulate exam conditions, including timing and negative marking. Analyze weak spots, speed, and accuracy. Mock tests aren’t just practice – they help you develop smart heuristics
9. Read Instructions Carefully on Exam Day
Before starting, thoroughly review instructions and marking schemes. Understand how many marks each question carries and how negative marking works. A good start sets the tone for the rest of the paper.
10. Double-Check If Time Permits
If you finish early, use your spare time to revisit flagged questions or review your answers. A quick review can catch silly mistakes that might cost valuable marks.
🧠 Sample Time-Management Plan (Per Section)
Phase | Time Allocation | Goal |
Scan & Solve | 30 mins | Quickly handle all easy questions (30–40% of total) |
Deep Solve | 90 mins | Tackle medium-difficulty questions smartly |
Revisit & Review | 30 mins | Attempt flagged/difficult ones or skip if unsure |
Final Review | Remaining time | Check answers, especially guessed ones |
Why This Strategy Works
Taking a strategic, intelligent approach means you’re not just attempting questions – you’re evaluating risk vs reward, managing time, and minimising errors. These techniques help optimise your score under pressure.
✅ Bonus Preparation Tips
- Strengthen conceptual clarity in both Math and GAT subjects.
- Familiarise yourself with the standard syllabus and exam pattern.
- Keep practising – previous papers and timed mocks are your best friends
- Maintain a calm mindset – test-day nerves can cost more than difficult questions.
Final Takeaway
Smartly attempting the NDA paper is as crucial as knowing the content. Apply this balanced approach of speed, accuracy, strategic guessing, and solid practice to maximise your score and rank. Your path to success lies not just in what you know, but in how wisely you apply it.
FAQs
Ans. Start with your strongest subject first – either Maths or English/GK – to build confidence and save time.
Ans. No. There is negative marking (⅓ mark deduction), so only attempt questions you’re reasonably sure of.
Ans. You get 2.5 hours for each paper. Aim to divide your time:
Maths: ~1.5 hours for solving, 1 hour for review
GAT: 1 hour for English, 1.5 hours for GK and current affairs
Ans. Only guess if you can eliminate at least 2 options. Blind guessing will likely reduce your score.
Ans. Practice mock tests regularly to improve speed and accuracy. Skip tough questions initially and return later.
Accuracy matters more due to negative marking. A high number of attempts with poor accuracy will lower your score.
Ans. Extremely. Darken circles properly and mark the right section. Even correct answers won’t be counted if OMR is filled incorrectly.
Ans. Spending too much time on one tricky question and not attempting easier ones. Time lost here can cost you the exam.
Ans. Yes. Skipping doubtful or time-consuming questions is smart and strategic.
Ans. Take deep breaths, don’t panic if one section feels tough – focus on maximising your score, not perfection.
