NDA 1 2027 Eligibility Criteria
Who can apply for NDA 1 2027? Only unmarried male and female candidates born between approximately 2 July 2008 and 1 July 2011 (age 16.5–19.5 years), who have passed or are appearing in Class 12. Candidates for the Air Force, Navy and Naval Academy must have Physics, Chemistry and Mathematics in Class 12; the Army Wing accepts any stream.
Exact birth-date limits are confirmed in the official notification, but the standard 16.5–19.5 age band means current Class 10 and Class 11 students are squarely in the target group. That early-stage window is exactly why starting now pays off so heavily.
NDA 1 2027 Exam Pattern
| Paper | Subject | Marks | Duration |
|---|---|---|---|
| Paper I | Mathematics | 300 | 2.5 hrs |
| Paper II | General Ability Test (GAT) | 600 | 2.5 hrs |

Negative marking applies (−0.83 in Maths, −1.33 in GAT). For the full section-wise weightage, see our NDA exam pattern guide and the complete NDA syllabus breakdown — the structure carries over to 2027.
Why Start NDA 1 2027 Preparation Now
With the exam on 11 April 2027, you have roughly ten months. That is the ideal runway — long enough to build deep conceptual mastery rather than cram, and to develop the Officer-Like Qualities the SSB rewards, which cannot be rushed. Students who start a year out consistently outperform last-minute aspirants for three reasons:
- Concept depth: Mathematics and GAT reward understanding built over months, not memorisation.
- SSB readiness: Officer-Like Qualities, spontaneity and communication develop gradually with practice.
- Revision cycles: An early start allows multiple full-syllabus revisions and dozens of mock tests before April 2027.
How to Start Preparing for NDA 1 2027
- Master the basics first: Build a strong NCERT foundation in Maths and Science (Class 11–12 level).
- Follow a year-long plan: Use a structured 12-month roadmap so every month has clear targets — see our NDA 2027 one-year study plan.
- Build a daily current-affairs habit: GK carries 400 marks in the GAT; start now.
- Begin SSB awareness early: Understand the 5-day process and start developing OLQs via the SSB OIR guide.
- Decide coaching vs self-study: Choose the path that fits you — compared in our NDA coaching vs self-study guide.
Still in Class 9 or 10? Start the Foundation
If you are in Class 9 or 10 and dream of the NDA, you have the biggest advantage of all — time. An early foundation in mathematics, English and fitness, plus exposure to the defence mindset, makes the eventual NDA preparation far easier. See our NDA preparation after Class 10 guide to start the right way.
What You Are Working Toward
Clearing NDA 1 2027 means a fully-funded officer’s training at the National Defence Academy and a career with strong pay, prestige and lifelong benefits. To see the payoff, read about the NDA officer salary and rank-wise pay, and the score you will need via the NDA cut off and predictor.
NDA 1 2027 Selection Process
Selection runs in three stages, and understanding the full journey early helps you prepare for all of it — not just the written exam:
- Written exam (900 marks) — Mathematics and the GAT on 11 April 2027. Clearing the cut off shortlists you for the SSB.
- SSB Interview (900 marks) — a 5-day assessment of Officer-Like Qualities across screening, psychology, GTO tasks and the personal interview.
- Medical examination — final fitness check before the merit list is drawn down to the available vacancies.
Because written and SSB marks are equal, the final merit (out of 1800) rewards all-round candidates. To see the score you should target, use the NDA cut off and predictor.
