The NDA written exam safe score is generally considered to be 360 to 400 marks out of 900. While the official UPSC cut-off often hovers between 320 and 355, aiming for 400+ ensures a comfortable buffer, significantly increasing your chances of clearing the threshold and securing a high rank.
What is the Exam?
The National Defence Academy (NDA) examination is a prestigious national-level entrance test conducted twice a year by the Union Public Service Commission (UPSC). It serves as the gateway for young aspirants to join the Indian Army, Navy, and Air Force wings of the NDA and the Indian Naval Academy Course (INAC). This exam evaluates candidates on their mathematical ability, general awareness, and English proficiency, followed by an intensive Services Selection Board (SSB) interview process.

Preparation Strategy
At Exam Bhai, we emphasize a structured approach to hit that safe score.
- Subject Prioritization: Mathematics carries significant weightage. Dedicate 60% of your daily study time to mastering formulas and shortcuts. If you are struggling with specific sections, use our specialized resources to improve your speed in Mathematics for Defence.
- GAT Mastery: Do not neglect GAT. English is a scoring section. Focus on reading editorials and brushing up on basic grammar. For General Science and Social Studies, rely on NCERT books.
- Mock Test Integration: Consistency is key. You should analyze your performance in previous year NDA papers to identify weak spots.
- Time Management: During the exam, focus on accuracy over attempt count to avoid negative marking.
Cut-Off Trends
Historical data sourced from upsc.gov.in suggests that the cut-off fluctuates based on the difficulty level of the paper and the number of candidates. Historically, the cut-off for the written exam ranges between 320 to 355 marks out of 900. However, relying on the minimum cut-off is risky. A "Safe Score" strategy requires you to aim at least 50 marks above the previous year's trend to account for any surprises in the paper's difficulty.
Frequently Asked Questions
