Failed NDA (National Defence Academy)? Here's Your Recovery Plan

Pro tip: Contact the exam provider directly for their specific retake policy.

• Treating the General Ability Test as one undifferentiated block and revising it as generic general knowledge.
  UPSC publishes the weights inside Part B: Physics 25 percent, Chemistry 15 percent, General Science 10 percent, History and Freedom Movement 20 percent, Geography 20 percent, Current Events 10 percent. Physics alone is worth about 100 marks, more than Chemistry and General Science combined. Allocate revision hours to those weights instead of splitting time evenly.
• Practising Mathematics with a calculator during preparation.
  The Commission states that candidates are not permitted to use a calculator, mathematical table or logarithmic table, and instructs them not to bring these into the hall. Every practice session should be done with pen, paper and mental arithmetic, or your speed estimates from home will not survive the 2 hour 30 minute paper.
• Guessing freely because there are only four options and the odds look acceptable.
  UPSC deducts one third of the marks assigned to the question for a wrong answer, so a wrong answer forfeits its own mark and a third of another. The Commission does not publish a per-paper question count, so work the penalty as a proportion rather than as a fixed mark figure. Marking two options counts as wrong even if one is correct. A blank carries no penalty, so an uncertain question left blank is genuinely cheaper than a coin flip.
• Preparing only for the written paper and treating the SSB as something to worry about later.
  The SSB Test and Interview is worth 900 marks against 900 for the entire written examination, so it is exactly half the final merit. Start the Officer Intelligence Rating drills, picture perception writing and physical conditioning in parallel with the written syllabus, not after the written result.
• Ignoring the device list in the Physics syllabus because it looks like trivia.
  UPSC names the simple pendulum, siphon, levers, balloon, pumps, hydrometer, pressure cooker, thermos flask, telegraph, telephone, periscope, telescope, microscope, mariner's compass, lightning conductor and safety fuse in the syllabus, and questions on their general working principle recur. Make one sheet with the principle behind each and revise it, because it is guaranteed-syllabus material.
• Getting the date of birth or roll number encoding wrong on the OMR sheet.
  UPSC states that any omission, mistake or discrepancy in encoding details on the OMR answer sheet, especially the Roll Number and Test Booklet Series Code, renders the sheet liable for rejection. Encode those fields first, in black ball pen only, and verify them before answering a single question.
• Assuming an application can be corrected after submission.
  The Commission allows no correction, alteration or modification in any field of the application form after submission, and applications cannot be withdrawn. Service preferences, once entered, cannot be added to or altered. Check date of birth against the Matriculation certificate and check your service preference order before you submit.
• Skipping the service preference field or filling only one preference.
  UPSC states that candidates are considered only for services for which they express a preference, and for no others. Filling one preference when you would accept several narrows your chances against 394 vacancies split across four streams. It is mandatory to exercise at least one preference, and the Commission advises indicating as many as you are willing to accept.
• Arriving at the venue close to the start time.
  Entry closes 30 minutes before each session begins and no candidate is allowed in afterwards under any circumstance. Face authentication, identity verification and frisking all happen before that closure. For NDA II 2026 that meant being inside the venue by 9:30 A.M. for Mathematics and 1:30 P.M. for the General Ability Test.

• Strong in Mathematics is essential
• General ability: English, GK, Geography, Physics, Chemistry
• SSB tests physical fitness, train for it
• SSB interview is 5-day assessment
• Age limit: 16.5-19.5 years (after 12th)
• Practice previous year papers
