For the NDA 2026 examination, each incorrect answer attracts a penalty of $1/3$ of the marks assigned to that question. In the Mathematics paper, where each question carries 2.5 marks, an incorrect response deducts approximately 0.83 marks. The GAT paper penalizes incorrect answers with roughly 1.33 marks per mistake.

Eligibility Criteria
According to the official guidelines published on upsc.gov.in, candidates must meet specific age, educational, and physical standards. Applicants must have completed or be appearing for their 10+2 examinations. For the Air Force and Naval wings, Physics and Mathematics as subjects in 10+2 are mandatory. Physical fitness parameters are strictly enforced to ensure candidates can withstand the rigors of military training.
Application Process
The application process is conducted online via the UPSC portal. Candidates must possess a valid Photo ID, scanned copies of their documents, and ensure payment of the requisite examination fee. Once the window opens, we urge candidates to register early to secure their preferred exam center.
Preparation Strategy
Strategic preparation is the key to managing negative marking. We at Exam Bhai emphasize:
- Selective Attempting: If you are unsure of an answer, it is mathematically better to leave it than to risk a penalty. Use the latest Defence exam question banks on Exam Bhai to learn which questions to skip.
- Time Management: Divide your time to ensure all easy questions are tackled first.
- Accuracy Over Volume: Aim for high accuracy in subjects like English and General Science to build a safety buffer.
Cut-Off Trends
Based on historical data from upsc.gov.in, the cut-off marks for the written examination typically range between 300 and 360 marks out of 900. These trends indicate that a score above 400 is considered safe. However, because of the penalty system, attempting all questions blindly can significantly lower your total score, potentially pushing you below the qualifying threshold.
Frequently Asked Questions
Q1: Is there a different negative marking for different sections in GAT? No, the $1/3$ penalty applies uniformly across the GAT paper for all sections.
Q2: Does leaving a question blank affect my score? No, blank questions result in zero marks—they neither add nor subtract from your total.
Q3: How is the final score calculated? Final Score = (Total Correct × Marks per question) - (Total Incorrect × 1/3 of Marks per question).
Q4: Should I guess if I am confused between two options? Mathematically, unless you can eliminate at least two options, guessing is risky. The probability of losing marks is higher than the probability of gaining them.
Q5: Can I get negative marks for an unattempted question? Absolutely not. Only attempted questions that are incorrect attract penalties.
Q6: What is the best way to practice for the negative marking system? Regularly taking full-length mock tests under timed conditions is the best way to build the instinct of knowing when to stop attempting.
