The UPSC National Defence Academy and Naval Academy Examination (II), 2026 is scheduled for Sunday, 13 September — Mathematics in the morning shift, the General Ability Test in the afternoon. With roughly twelve days on the clock, this is exactly the point where aspirants make the wrong call: either abandoning revision to start new topics, or trying to re-read the entire syllabus cover to cover. Neither works. The last twelve days have one job — convert what you already know into marks you reliably score, not to expand what you know.
Start by pulling out every mock test and sectional test you've taken in the last two months and building a simple error log: which topics cost you marks, and whether the mistake was conceptual (you didn't know it) or procedural (you knew it but slipped under time pressure). Procedural errors — sign mistakes, misreading a question, running out of time on the last ten questions — usually account for more lost marks than genuine knowledge gaps this close to the exam, and they're fixed by drilling exam conditions, not by studying more theory.
Days 1–5: close the highest-frequency gaps
Rank your weak topics by how often they actually appear in past papers, not by how uncomfortable they feel. In Mathematics, that usually means Trigonometry, Algebra and Coordinate Geometry carry more weight than Statistics or Vectors — shore up the high-frequency chapters first. In the General Ability Test, English and General Science questions are more numerous and more scorable under time pressure than the less predictable Current Affairs section, so a disciplined revision of grammar rules and NCERT-level Physics/Chemistry pays off faster than chasing news from the last six months.
Days 6–9: full-length papers, real conditions
Sit at least three full-length papers in this window, at the same time of day as your actual shifts (Maths 10 a.m.–12 p.m., GAT in the early afternoon), with no phone, no pausing, and a printed OMR-style answer sheet if you can arrange one. The goal isn't a new high score — it's calibrating your pacing so that on exam day, checking the clock feels automatic rather than anxious. After each paper, spend at least as long reviewing wrong answers as you spent taking the test.
Days 10–12: taper, don't cram
- Stop attempting new full-length papers after day 9 — use the last three days for light revision of formula sheets, GK notes and English rules only. - Sleep on a fixed schedule matching exam-day timings, so your body is alert during the actual Maths and GAT windows, not just whenever you naturally wake up. - Locate your exam centre in advance if you haven't already, and plan the journey with a wide safety margin — arriving flustered costs more marks than any last-minute revision saves. - Keep your admit card, a valid photo ID and the permitted stationery ready two days ahead, not the night before.
On exam day itself
Attempt every question you're reasonably confident about first, on both papers, before returning to the ones you're unsure of — NDA's negative marking punishes guesswork on Mathematics far more than a few unattempted questions do. In the GAT, English and easier General Science questions are worth answering fast to bank time for the longer Current Affairs and reasoning questions later in the paper.
Remember the exam is only stage one
Clearing the written paper opens the door to the SSB interview, where a very different set of skills is assessed over five days. If Mathematics and GAT are where most of your last twelve days are going — as they should be — it's still worth keeping fifteen minutes a day for reading a newspaper editorial or discussing current affairs out loud with a friend, since that habit compounds far better started now than crammed the week before your SSB call-up.
