NDA 2026 Notification, Exam Pattern, Syllabus, Vacancies, SSB and Free Mock Tests

The National Defence Academy examination is the earliest entry into the officer cadre of the armed forces — candidates apply while still at school or just after, and successful ones join a three-year academy programme before commissioning into the Army, Navy or Air Force.

Its written paper is demanding but conventional: mathematics and a general ability test, both at school level, weighted 300 and 600 marks. What is not conventional is what follows. The Services Selection Board is a five-day assessment carrying as many marks as the entire written examination, and it tests things no amount of syllabus preparation will develop.

NDA notification and key dates

Checked 18 September 2026 on upsc.gov.in, where the provisional answer keys of NDA and NA Examination (II) 2026 are now posted for representations. NDA and NA Examination (II) 2026 was notified on 20 May 2026 with 394 vacancies, applications closed on 9 June, and the written examination was held on 13 September 2026 — the same day as CDS II. Its written result is due about eight weeks after the examination, as NDA I’s was: the NDA I 2026 examination of 12 April 2026 had its written result on 8 May 2026, for the 157th course commencing 1 January 2027, and SSB interviews have been running since. The NDA II 2025 final result of 8 April 2026 listed 742 candidates in order of merit for the 156th course. The 2027 calendar places NDA I 2027 on 11 April 2027 (notification 2 December 2026, applications to 22 December) and NDA II 2027 on 19 September 2027.

Men and women are separate entries

The notification is common and the written examination is common, but the written results and the final merit lists for men and women are prepared separately against the vacancies notified for each, service by service. The 24 women’s vacancies are therefore a separate competition, not a quota inside the 394.

Overview

What NDA is, and who it suits

The NDA examination is held twice a year and leads to the three-year programme at the National Defence Academy at Khadakwasla, followed by service-specific training and commissioning as an officer. Candidates for the Naval Academy’s ten-plus-two cadet entry are selected through the same examination.

Eligibility is tied closely to schooling. Candidates apply while in class 12 or shortly after, within a narrow age band, and the Air Force and Naval wings require physics and mathematics at the twelfth level while the Army wing does not. Because the age window is short, most candidates have only two or three genuine opportunities.

The two halves of the selection

  • The written examination — 900 marks — mathematics at 300 marks and the General Ability Test at 600, both at class 12 level, both with negative marking.
  • The Services Selection Board — 900 marks — a five-day assessment covering screening, psychological testing, group tasks and a personal interview.
  • The medical examination — against demanding armed forces standards, with wing-specific requirements that are strictest for flying branches.

The SSB is half the marks and cannot be crammed

Candidates routinely spend a year on the written papers and a fortnight on the Services Selection Board, despite the two carrying equal weight. The SSB assesses officer-like qualities through psychological tests, group tasks and interview — attributes built through years of activity, responsibility and reading rather than through last-minute coaching.

Eligibility

Who can apply for NDA

Eligibility is judged as on the date the course commences and verified by the Services Selection Board and the Academy. The age window is narrow — three years — and the candidate must be unmarried throughout training.

Age and marital status, from the two 2026 notifications.
CycleDate of birthCondition
NDA I 2026 (course from 1 January 2027)2 July 2007 – 1 July 2010Unmarried men and women; marriage during training leads to discharge and refund of training costs
NDA II 2026 (course from 1 July 2027)1 January 2008 – 1 January 2011As above

Educational qualification

  • Army wing of the NDA — Class 12 of the 10+2 pattern or equivalent from a state board or university.
  • Air Force and Navy wings of the NDA, and the Naval Academy 10+2 cadet entry — Class 12 with physics, chemistry and mathematics.
  • Appearing candidates — Candidates in class 12 may apply and must produce proof of passing by the date the notification fixes, before the SSB or the course.

Other conditions

  • Nationality — Indian citizens, and subjects of Nepal and Bhutan, Tibetan refugees who came before 1962 and persons of Indian origin migrated from the listed countries with a certificate of eligibility (not needed for Gorkha subjects of Nepal).
  • Fee — ₹100 online; women, SC, ST and wards of JCOs, NCOs and other ranks as the notification specifies are exempt.
  • Physical standards — Height, weight and vision standards by service in the notification’s appendix; the Air Force flying branch and the Navy have the strictest vision limits, and candidates are advised to have a medical check before applying.

Selection process

How NDA selection works

Each stage in order, and what it actually tests.

Stages change between cycles. Confirm the structure in the notification for the cycle you are sitting.
StageFormatWhat it involves
Written examinationTwo objective papers on one day, 900 marksMathematics, 120 questions for 300 marks in two and a half hours, and the General Ability Test, 150 questions for 600 marks in two and a half hours — Part A English 200 marks and Part B General Knowledge 400 marks (physics 25 per cent, chemistry 15, general science 10, history 20, geography 20, current events 10). One third of the marks of a question is deducted per wrong answer. Mathematics and Part B are set bilingually.
SSB interviewFive days, 900 marks, two stagesCandidates above the written cut-off register on joinindianarmy.nic.in within two weeks of the written result and are allotted a Selection Centre. Stage I (Officer Intelligence Rating and Picture Perception and Description) screens on day one; stage II runs psychology tests, group tasks and the interview over four days, followed by the conference. Air Force candidates additionally take the Computerised Pilot Selection System.
Medical examination and final meritBoard medical, then a UPSC merit list out of 1,800Recommended candidates are medically examined; the final merit list of written plus SSB marks is published by UPSC, separately for men and women and by service preference, and the Academy issues joining instructions for the course — the 157th NDA course from January 2027 for NDA I 2026 and the 158th from July 2027 for NDA II 2026.

Application to the Academy

The steps in the order they happen, with the fees and windows the 2026 notifications specify.

The NDA process, from registration to recommendation

  1. Create the account and the Universal Registration Number profile on upsconline.nic.in The Commission’s portal has four modules: account creation, universal registration (the URN profile with your identity, photograph, signature, photo-ID and educational particulars), a common application form, and an examination-specific form. The first three are filled once and reused for every UPSC examination; the URN profile must be locked before an examination form can be submitted, and the photo-ID entered there is the one carried to every stage.
  2. Fill the examination-specific form in the notified window Choose the centre, the medium and language options, the optional subject or service preferences where the notification asks for them, claim any category, PwBD or fee-remission benefit with the certificate details, and submit before 6 p.m. on the last date. A withdrawal window of about a week usually follows the closing date for candidates who no longer wish to appear.
  3. Pay the fee ₹100, paid online; nil for women, SC, ST and the wards of JCOs, NCOs and other ranks listed in the notification.
  4. e-Admit card Issued on the portal about a week to ten days before the examination; it is not posted. Print it, check the photograph and the centre, and carry it with the photo-ID named in the URN profile. Centres are allotted first-come, and a candidate who does not get a preferred centre is allotted another in the same region.
  5. The written examination Objective papers are answered on an OMR sheet in black ballpoint pen, with the question paper series and roll number coded by hand — the Commission publishes a note on the common OMR mistakes that lead to rejection. Conventional papers are handwritten in the question-cum-answer booklet. Provisional answer keys are opened for representations on the portal within a week of an objective paper.
  6. Result and the next stage Results are published as roll-number lists on upsc.gov.in with a press note; marks and cut-offs are released only after the final result. Qualified candidates get a window on the portal to pay the next-stage fee, update details and submit the detailed application form where the examination has one.
  7. Written result and SSB registration The written result is a roll-number list about eight weeks after the examination. Qualified candidates must register on joinindianarmy.nic.in within two weeks of the result to be allotted a Selection Centre and SSB dates, which are sent by e-mail.
  8. SSB: stage I on the day of reporting Officer Intelligence Rating tests and the Picture Perception and Description Test; candidates are screened in or out the same day on the combination of the two.
  9. SSB: stage II over four days Psychology tests, Group Testing Officer tasks and the interview, then the conference. Air Force candidates who are recommended also take the Computerised Pilot Selection System, a once-in-a-lifetime test; those who failed it or the earlier PABT are not eligible for the flying branch.
  10. Medical examination and the final merit list Recommended candidates are medically examined by a board; the final merit list combines written and SSB marks, which carry equal weight, and is published by UPSC with a press note. The Services then issue joining instructions for the course.

Register for the SSB within two weeks

The written result’s press note is explicit: candidates who do not register on the Army recruiting website within two weeks of the result are not allotted SSB dates. Candidates already registered from an earlier attempt need not register again.

Each mathematics question carries 2.5 marks and each GAT question 4, so a wrong answer costs 0.83 and 1.33 respectively. The Commission fixes a minimum in each paper as well as an aggregate cut-off; NDA II 2025’s final result listed 742 candidates.

Study plan

How to prepare for NDA

NDA is a class-12 syllabus examined for speed and accuracy — 120 mathematics questions in 150 minutes, 150 GAT questions in 150 minutes — with a third off per error, and then an SSB that carries as much as the paper. Prepare mathematics to fluency, the GAT sections in their notified weights, and the SSB from the first month.

A six-month plan

  1. Months 1–2: mathematics to speed Algebra, matrices, trigonometry, analytical geometry, calculus, vectors, statistics and probability from class 11–12, with timed sets from previous papers.
  2. Months 3–4: GAT by weight Physics and chemistry to class 12 (40 per cent of Part B), history and geography (40 per cent), general science and current events; English grammar, vocabulary and comprehension for the 200-mark Part A.
  3. Month 5: full mocks A full 900-mark mock every week with the deduction applied and an error log; running, group discussion and self-description practice for the SSB.
  4. Month 6: revision and the examination Revise from notes; taper mocks; prepare the SSB file — PIQ form, current affairs, why the forces — and keep fitness up.

What the pattern means for the attempt

  • GAT is two thirds of the written marks — Four marks a question against 2.5 in mathematics; a candidate weak in mathematics can still clear the aggregate on a strong GAT.
  • A third off per error — At 1.33 marks per wrong GAT answer, blind guessing is expensive; two-option guesses only.
  • The SSB is half the merit — Written toppers fail the SSB every cycle; it is prepared, not attended.

Questions

NDA — FAQs

How much does the SSB interview count in NDA?

Nine hundred marks — exactly as much as both written papers combined. It runs over five days and covers screening, psychological testing, group testing officer tasks and a personal interview. Because it assesses officer-like qualities such as initiative, cooperation, resilience and clarity of thought, it rewards years of activity, responsibility and reading rather than weeks of coaching. Candidates who spend a year on the written papers and a fortnight on the SSB are preparing for half the examination.

Which is more important in NDA, Mathematics or General Ability?

The General Ability Test, by mark weight — 600 marks against 300 for mathematics. Within it, General Knowledge alone carries 400 marks, more than the entire mathematics paper, and it draws on class 11 and 12 physics and chemistry more heavily than the label suggests. Candidates who are strong in mathematics but casual about general knowledge are optimising the smaller half of the written examination.

How should I prepare for the NDA SSB?

Over months, not weeks, and through activity rather than study. The board assesses initiative, cooperation, decisiveness, physical robustness and the ability to think and speak clearly under pressure. Building those means taking responsibility in group settings, maintaining genuine physical fitness, reading widely enough to hold views, and practising expressing them. Format familiarisation and mock interviews are useful in the final weeks, but they refine what is already there rather than creating it.

What are the NDA 2026 exam dates?

NDA I 2026 was held on 12 April 2026 with the written result on 8 May; NDA II 2026 was notified on 20 May with applications to 9 June and was held on 13 September 2026, with the written result due about eight weeks later. NDA I 2027 is on the UPSC calendar for 11 April 2027, with the notification on 2 December 2026 and applications to 22 December.

What is the NDA exam pattern?

A written examination of two objective papers on one day — Mathematics, 120 questions for 300 marks in two and a half hours, and the General Ability Test, 150 questions for 600 marks in two and a half hours, of which English is 200 and General Knowledge 400 — with one third of the marks of a question deducted per wrong answer; then an SSB interview of 900 marks over five days. The final merit is out of 1,800.

How many vacancies are there in NDA 2026?

394 in each cycle: Army 208, Navy 42, Air Force 120 (Flying 92, Ground Duty Technical 18, Ground Duty Non-Technical 10) and the Naval Academy 10+2 cadet entry 24, of which 24 across the wings are for women and are filled through a separate merit list.

Who is eligible for NDA, and what is the age limit?

Unmarried men and women who have passed class 12 — with physics, chemistry and mathematics for the Navy, Air Force and Naval Academy — and were born between 1 January 2008 and 1 January 2011 for NDA II 2026 (2 July 2007 to 1 July 2010 for NDA I 2026). Class-12 candidates awaiting results may apply. Physical and vision standards apply by service.

Is there negative marking in NDA?

Yes — one third of the marks of the question for every wrong answer: 0.83 marks in Mathematics (2.5 per question) and 1.33 in the General Ability Test (4 per question). Unanswered questions are not penalised.

Are there free NDA mock tests?

Yes. The free NDA mock tests here follow the 2026 pattern — 120 mathematics questions and 150 GAT questions on the two-and-a-half-hour clocks, with the one-third deduction applied and section-wise scores for the GAT weights — so you can see where you stand against the written cut-off.

What is the NDA SSB interview?

A five-day assessment at a Services Selection Board worth 900 marks, equal to the written examination. Stage I on the first day is an Officer Intelligence Rating test and a Picture Perception and Description Test that screens candidates out; stage II over the next four days is psychology tests, Group Testing Officer tasks and a personal interview, followed by the conference. Air Force flying-branch candidates who are recommended also take the Computerised Pilot Selection System, which can be attempted only once.
