Guides on the pattern, eligibility, life at the Academy, preparing alongside Class 12, study plans, negative marking, merit and the entry for women. UPSC fixes qualifying marks at its discretion, so treat any per-paper minimum you read online as unconfirmed.

Study in this order

  1. 1The NDA exam pattern explainedTwo written papers — Mathematics and the General Ability Test — then a two-stage SSB. The NDA pattern explained in plain language, with marks, negative marking, qualifying rules, the GK weightage and how the final merit list is made. 7 min read
  2. 2NDA eligibility: age, education and physical standardsNDA has strict eligibility — a narrow birth-date window, rules on marital status, PCM for the Navy and Air Force, a one-time pilot aptitude test and medical standards. What to check, how to count your attempts, and what trips candidates up. 6 min read
  3. 3Life and training at the National Defence AcademyThree years at Khadakwasla, a degree from JNU, then a year or more at a service academy before you are commissioned. What NDA training involves, how each wing's path differs, what a cadet's day looks like, and why knowing this helps at the SSB. 6 min read
  4. 4The NDA syllabus, analysedClass 11–12 mathematics, an English section on grammar, vocabulary and comprehension, and a GK paper whose weightage the notification itself spells out. The syllabus section by section, the topics people miss, priorities and a tracker. 7 min read
  5. 5Preparing for NDA alongside Class 12Most NDA candidates prepare while in Class 12 — an advantage, because much of the maths and science overlaps. How to turn board study into NDA marks, what needs separate work, a weekly routine and a year-long calendar around board exams. 6 min read
  6. 6A six-month NDA planSix months is a good window to prepare seriously for the written exam while building SSB readiness. A month-by-month plan for maths, GK and English, a weekly template, mock-test schedule, checkpoints and what to do when you fall behind. 6 min read
  7. 7Negative marking and accuracy in NDAIn NDA, a wrong answer costs one-third of the question's marks. That makes blind guessing pointless and careless mistakes expensive. The arithmetic of guessing, when an informed guess pays, a three-pass method for the paper and habits that raise accuracy. 6 min read
  8. 8Mock tests and previous papers for NDAUPSC repeats its style more than its questions. Previous papers show the real level; mocks build timing and accuracy. When to start, how to simulate the exam, how many to take, and a worked example of learning from one paper. 6 min read
  9. 9How NDA merit and cut-offs workTo reach the SSB you must clear a minimum in the written exam, and to be selected you must clear the SSB too. The final merit list adds both. How each hurdle works, how ties are broken, how services are allotted, and how to set a sensible target score. 6 min read
  10. 10Common NDA mistakesCandidates who narrowly miss NDA usually share a few habits — preparing only maths, guessing blindly, skipping previous papers, and leaving the SSB and fitness until after the written result. Twelve common mistakes, why they happen, and how to fix each. 6 min read
  11. 11NDA for women candidates: eligibility, preparation and the SSBWomen have been eligible for NDA since 2021. The written exam and SSB are the same, but vacancies and merit lists are separate. What women candidates should check, how to prepare, and how to build fitness and medical readiness in time. 6 min read
  12. 12The last month before the NDA examOne month to go. Stop opening new chapters, sit full papers under exam conditions, revise actively, and plan exam day down to the minute. A week-by-week plan, a mock-analysis method, an attempt strategy and an exam-day routine. 6 min read
