In the UPSC NDA 2026 exam, a negative marking of $1/3$ of the marks assigned to each question is deducted for every incorrect answer. To maximize your score, adopt a 'selective attempt' strategy: prioritize high-confidence questions, eliminate clearly incorrect options, and skip ambiguous items to prevent cumulative mark erosion.
What is the Exam?
The National Defence Academy (NDA) examination is one of the most prestigious competitive tests in India, conducted biannually by the Union Public Service Commission (UPSC). It serves as the gateway for young aspirants to join the Army, Navy, and Air Force wings of the NDA and the Indian Naval Academy Course (INAC). We at Exam Bhai view this not merely as a test, but as a rigorous filtration process designed to identify candidates with the right blend of intellectual acuity, physical fitness, and officer-like qualities. The exam is divided into two primary papers: Mathematics and the General Ability Test (GAT).

Preparation Strategy
Success in NDA requires a strategic approach to negative marking.
- The Two-Pass Method: Scan the paper twice. In the first pass, solve only those questions you can answer within 30-40 seconds. In the second pass, revisit questions where you can eliminate at least two options.
- Accuracy Over Volume: Because $1/3$ of the marks are docked for incorrect responses, attempting 80 questions with 90% accuracy is mathematically superior to attempting 110 questions with 60% accuracy.
- Use Digital Tools: You can start your journey with our advanced diagnostic test series for Defence on Exam Bhai to identify your error-prone areas and work on them before the actual exam.
Cut-Off Trends
Historically, the UPSC cut-off for the written examination typically ranges between 340 and 360 marks out of 900. These figures are periodically updated on the official upsc.gov.in website. Please note that the cut-off fluctuates based on the difficulty level of the paper and the number of vacancies available.
Frequently Asked Questions
1. Is there negative marking for unattempted questions? No, there is no penalty for questions left blank. Only incorrect answers attract negative marks.
2. How is the penalty calculated for Mathematics? Since each question carries 2.5 marks, a wrong answer results in a deduction of $2.5 \div 3 = 0.833$ marks.
3. Should I guess if I am confused between two options? We suggest that if you can eliminate two options, the probability of guessing correctly ($50%$) justifies the risk; however, avoid blind guessing.
4. Is the negative marking the same for all sections? Yes, the rule is uniform: $1/3$ of the marks assigned to the question are deducted regardless of the subject.
5. Does the negative marking include the GAT section? Yes, the GAT paper, which includes English and GK, follows the same $1/3$ negative marking policy for every incorrect response.
6. How do I improve my accuracy to avoid negative marking? Consistent practice through mock tests and analyzing your 'silly mistakes' is the only proven method to improve accuracy.
