A complete, honest guide to preparing for National Defence Academy & Naval Academy Examination: a real self-study path, a weekly study plan, how tough it actually is, and what the job pays. Everything you need is free on Shishya — no coaching fees.
The NDA exam is one of the few competitive exams where disciplined self-study genuinely works as well as coaching — provided you start early and stay consistent. Here's your honest roadmap:
Mathematics (300 marks): This is your Class 11-12 NCERT syllabus. Not a single mark beyond that. Get NCERTs for both years (Mathematics) and solve every example, every exercise, every miscellaneous problem. Twice. The exam tests speed and concept clarity, not puzzle-solving. After NCERTs, move to Pathfinder for NDA/NA by Arihant or RS Aggarwal's NDA Mathematics. Don't hoard books — one good book, solved cover-to-cover, beats five half-read ones.
English (200 marks): This section tests grammar fundamentals, vocabulary, comprehension, and basic writing (précis, essay). For grammar, Wren & Martin is overkill; instead, use Lucent's General English or any good school-level grammar book. Read one newspaper editorial daily — The Hindu or Indian Express — and note down 5 new words with meanings. For comprehension, practice is everything. Shishya's free PYQ papers are gold here; the comprehension passages repeat in style and difficulty.
General Knowledge (400 marks): This is the monster section. It covers Physics, Chemistry, Biology (Class 9-10 level), History, Geography, Polity, Economics, Current Affairs, and Defence-specific GK. The syllabus looks massive but the depth is school-level. Start with NCERTs: Science (9-10), History (Ancient to Modern, 6-12), Geography (6-12), Political Science (9-12), Economics (9-10). These aren't optional — 60% of GK questions come straight from these. After NCERTs, get Lucent's General Knowledge or Arihant's General Knowledge (both are comprehensive and affordable). For current affairs, follow any monthly current affairs magazine (Pratiyogita Darpan) or use free YouTube channels like Study IQ. Defence-specific topics (ranks, medals, military history, equipment) need focused reading — dedicate 2 weeks to this using free PDFs available online or NDA-specific GK books.
The Shishya advantage: Coaching charges ₹40,000–₹80,000 for NDA prep, mostly for test series and doubt-solving. Shishya gives you unlimited free mock tests that mirror the actual exam pattern, previous year questions (PYQs) that reveal exactly what UPSC asks repeatedly, and notes that condense the sprawling syllabus. Use PYQs to identify your weak chapters, then go back to NCERTs/reference books for those chapters. Mocks should start 3 months before the exam — take one full-length test every Sunday, analyse wrong answers the same evening, revise those topics during the week.
If you do take coaching: It helps mainly if you're weak in Mathematics or lack self-discipline. A good coaching centre will give you structured revision and peer competition. But remember, they follow the same sources — NCERTs, standard reference books, PYQs. If you're self-motivated and can follow a timetable, save the money.

Study plan
This is a 6-month plan assuming you're in Class 12 or have just finished. If you have more/less time, scale proportionally. The plan assumes 4–5 hours of focused daily study (more during holidays, less during school days).
Month 1–2: Foundation (NCERT + Basics)
*Mathematics (2 hours/day)*: Complete Class 11 NCERT. One chapter every 2–3 days. Solve all examples first, then exercises. Don't skip the miscellaneous exercises at chapter end. Make a notebook of formulas and mark difficult problems for revision.
*English (45 min/day)*: Grammar basics — tenses, voice, narration, sentence correction. Read one editorial, write down 5 words. Solve 2 comprehension passages per week from any old competitive exam paper.
*GK (1.5–2 hours/day)*: Science NCERTs (9-10) Physics, Chemistry, Biology. These are short; finish in 3 weeks. Then start History NCERT (Ancient India, Class 6-7). Make short notes — timelines, key concepts. Don't try to memorize everything; understand the flow.
*Sunday*: Revision day. Redo difficult Math problems. Revise notes. No new chapters.
Month 3–4: Building speed
*Mathematics (2 hours/day)*: Complete Class 12 NCERT. Simultaneously, start one reference book (Pathfinder/RS Aggarwal). Do chapter-wise practice — 20 problems per chapter. Focus on speed now; time yourself.
*English (45 min/day)*: Continue grammar (vocabulary, idioms, one-word substitutions). Start précis writing (one per week) and essay writing (one per fortnight). Use previous essay topics from NDA PYQs.
*GK (2 hours/day)*: Complete History NCERTs (Medieval and Modern, 8-12). Start Geography (6-12) — this is scoring. Focus on Indian Geography, world continents, climatic zones. Begin Polity NCERT (9-12). Current affairs — note down monthly important events (sports, awards, appointments, defence news).
*Sunday*: Take your first sectional mock from Shishya (Mathematics only or GK only). This will be painful; you'll score low. That's fine. Analyse every wrong answer.
*English (45 min/day)*: Practice, practice, practice. Comprehension passages (3 per week), error spotting, sentence improvement. Revise all grammar rules.
*GK (2–2.5 hours/day)*: Complete Polity and Economics NCERTs. Now pick up Lucent's GK or Arihant's GK compendium and read the consolidated sections (faster revision). Dedicate 10 days purely to Defence-specific GK — military ranks (Army, Navy, Air Force), major wars India fought, Defence Ministers, Chief of Defence Staff, important military equipment, medals and awards (Param Vir Chakra, Ashok Chakra, etc.), Defence Research and Development Organisation (DRDO) labs.
*Current affairs*: Last 6 months — sports (Olympics, Asian Games, cricket), important books and authors, national/international awards, new government schemes related to defence/youth.
*Sunday*: Full-length mock test (Paper I + Paper II, 5 hours). Analyse the same evening.
Month 6: Mocks + Revision
*Daily routine*: 40% revision (go through all formula sheets, short notes, maps), 30% mocks (alternate between full-length and sectional), 30% fixing weak areas.
*Week 1–2*: Take 4 full-length mocks (Sunday + one weekday). Focus on time management. In Mathematics, don't get stuck on one problem for more than 2 minutes. In GK, if you don't know, guess and move on.
*Week 3–4*: Light revision only. Go through all NCERTs one last time (just flip pages, read headings, see maps). Revise formula sheets daily. Take one final mock 3 days before the exam. Last 2 days — no new topics, just relax and stay confident.
Weekly structure (Mid-preparation phase)
Monday-Friday: 4–5 hours split as above
Saturday: Catch-up day (finish pending chapters, redo mistakes from last mock)
Sunday: Mock test (morning) + analysis (evening)
Adjustments: If you're still in school, reduce daily hours to 3 and extend the plan to 8–9 months. If you've already finished 12th and have 8+ hours, compress to 4 months but don't skip NCERTs.
Is it tough? An honest take for an average student
Short answer: NDA is moderately tough but entirely crackable for an average student with 6 months of honest preparation.
Why it feels tough:
The syllabus is vast (10th Science + 11th-12th Math + Humanities + Current Affairs + Defence GK)
It's a long exam (5 hours; stamina matters)
Mathematics has 120 questions in 150 minutes — speed is critical
Negative marking (0.33 marks per wrong answer) punishes random guessing
Why it's actually manageable:
Depth is shallow: Unlike JEE or NEET, NDA doesn't ask twisted or application-heavy problems. Math is straightforward NCERT-level. GK is factual, not analytical.
Repeat pattern: UPSC loves repeating question types. If you solve 10 years of PYQs, you'll see the same topics, same phrasing, same difficulty level.
No backlog if you're in 11th-12th: You're already studying the syllabus for boards. NDA is revision + slight addition (GK and Defence topics).
Cut-offs are reasonable: You don't need 90%. The written exam cut-off hovers around 35–40% aggregate (varies by attempt and category). Yes, you read that right. Scoring 320–360 out of 900 usually gets you through to SSB interview. That's 2 out of every 5 questions correct.
Real talk for the average student: If Math is your nemesis, you'll struggle — but you can compensate. Mathematics is 300 marks; if you manage even 100–120 there with safe attempts, and score well in GK (250+), you're through. Many students crack NDA with weak Math. However, you cannot ignore Math completely; do the easy chapters (Algebra, Trigonometry basics, Probability) and leave the tough ones (3D Geometry, Vector).
If you're weak in English, good news: it's only 200 marks and easier than GK. Basic grammar + newspaper reading for 6 months is enough for 120–140 marks.
The real filter: It's not the written exam; it's the SSB interview. NDA written clears about 8,000–10,000 candidates out of 4–5 lakh who appear. The psychological tests and interviews are where most get filtered. But that's a different battle — for the written exam, average intelligence + above-average consistency is enough.
Time management: This is the hidden difficulty. You get 2.5 hours for Math (120 questions) and 2.5 hours for GAT (150 questions). In both papers, slow students suffer. Practice mocks not just for accuracy but for speed. Learn to skip and return.
Bottom line: If you're reading this and thinking "I'm average in Math, decent in GK, can read English" — you can crack NDA. It doesn't need brilliance. It needs 6 months of daily 4-hour focus, solving NCERTs thoroughly, taking at least 15 full mocks, and managing exam-day nerves. The toughest part is the consistency, not the content.
Salary, job profile & career growth
Starting pay: Upon joining the National Defence Academy (Khadakwasur, Pune), cadets receive a stipend of approximately ₹21,000–₹25,000 per month during the three-year training period. After commissioning as a Lieutenant (Army), Sub-Lieutenant (Navy), or Flying Officer (Air Force), the starting salary is approximately ₹56,000–₹70,000 per month (Level 10 in Defence Pay Matrix as of 7th Pay Commission), plus allowances (DA, TA, HRA if applicable, field/flying allowance, etc.). Actual in-hand salary typically reaches ₹80,000+ per month for Lieutenants when all allowances are included.
Job profile: Post-commissioning, you serve as an officer in the Indian Army, Navy, or Air Force depending on the cadre you clear during NDA training. Roles vary: Army officers lead troops in combat/peacekeeping/counterterrorism; Navy officers serve on warships, submarines, or maritime operations; Air Force officers fly aircraft or handle technical/logistics roles. It's a field job involving postings across India and abroad, physical fitness requirements, and hierarchical discipline.
Career growth: Promotions are time-bound initially — Captain (3 years), Major (6–7 years), Lt Colonel (13 years), Colonel (20+ years). With exceptional service, you can reach Brigadier, Major General, and beyond. Salary at Colonel-level reaches approximately ₹1.5–1.8 lakh/month. Retirement after 20–30 years of service includes pension and post-retirement benefits. It's a stable, respectable career with housing, medical, education allowances, and canteen facilities.
Frequently asked questions
Q. What is the age limit for NDA exam?
A. 16.5 to 19.5 years as on the date mentioned in the notification. Typically, unmarried male candidates born between specific dates (example: July 2005 to July 2008 for an exam in 2024) can apply. Age criteria are strict; no relaxation.
Q. Can I give NDA after 12th Arts or Commerce, or is only Science stream eligible?
A. Army wing accepts all streams (Arts/Commerce/Science). Navy and Air Force wings require Physics and Mathematics in 10+2. So yes, Arts/Commerce students can apply but only for Army wing after NDA training.
Q. Is there negative marking? How much should I attempt to clear?
A. Yes, 0.33 marks deducted per wrong answer (one-third of question value). Attempting 180–200 questions out of 270 with 65–70% accuracy usually ensures clearing the written cut-off. Don't attempt blindly; educated guesses are fine if you eliminate 2 options.
Q. If I clear NDA written exam, what happens next?
A. You're called for SSB (Services Selection Board) interview, a 5-day process including psychological tests, group tasks, personal interview, and medical examination. Final selection depends on combined written + SSB performance. SSB has its own success rate (~10–15% of those appearing).
Q. Can female candidates apply for NDA now?
A. Yes, from 2022 onwards, female candidates are eligible for NDA after a Supreme Court order. Same exam, same process, same training. Age and eligibility criteria remain identical to male candidates.
