Complete Guide to NDA eligibility criteria 2026

Candidates aiming for NDA 2026 must be unmarried, aged between 16.5 and 19.5 years, and have passed or be appearing for Class 12. While the Army wing accepts any stream, the Air Force and Navy wings strictly require Physics and Mathematics. Meeting these core requirements is mandatory for final selection.

What is the Exam?

The National Defence Academy (NDA) examination is a prestigious national-level entrance exam conducted twice annually by the Union Public Service Commission (UPSC). It serves as the gateway for young aspirants to join the Indian Armed Forces (Army, Navy, and Air Force) as officers. We at Exam Bhai view this as more than just a test; it is an assessment of intelligence, physical grit, and officer-like qualities (OLQs) required to lead the nation's defence forces.

Application Process

The application process is conducted exclusively through the UPSC online portal. We recommend that candidates keep their matriculation certificate (for DOB verification) and Aadhar card handy. Candidates must fill in their preferences for the Army, Navy, and Air Force, as these cannot be changed once the application is submitted.

Preparation Strategy

To succeed in the 2026 cycle, we suggest a three-pronged approach:

1. Conceptual Clarity: Build a strong foundation using NCERT textbooks for Mathematics and General Science.
2. Mock Practice: Speed is as important as accuracy. Utilize targeted Defence mock tests on Exam Bhai to simulate the exam environment.
3. SSB Integration: Do not wait until the written results are out to start SSB preparation. Engage in public speaking, sports, and reading newspapers daily to develop the leadership qualities required for the personality test.

Cut-Off Trends

As verified by official results from UPSC, the written examination cut-off (out of 900) typically ranges between 290 and 360 marks.

• Recent Trends: In recent cycles, there have been instances of separate cut-offs for male and female candidates.
• Safety Margin: We advise students to aim for 370+ marks in the written exam to ensure a comfortable buffer. The total final selection cut-off (written + SSB) historically hovers around 650–730 marks out of 1800.
