NDA
NDA runs two stages that don’t resemble each other at all, and you have to pass both. The written stage is a pair of objective papers — mathematics and a general ability test — under the usual penalty case: rule out a wrong answer and the odds tilt your way, leave none ruled out and a blank is still the safer bet. The second stage is a multi-day board: intelligence tests, group tasks, a personal interview, all watched live by people trained to catch a rehearsed answer sliding past the question that was actually asked. It counts for as much as the whole written stage put together.
The two written papers aren’t weighted the same, so weight your study hours to match that split, not the size of either syllabus. The board is the interview tool at its widest — your own record, schooling and interests and choices, held as the why behind every line. Rehearse it with a stranger who follows up the way the real panel will, not alone with a list of model answers. Selection ranks you across both stages, so nothing less than the top will do, on either half: on paper, what’s missing is slips and time; at the board, it’s composure under a follow-up you didn’t see coming. Only a rehearsed room supplies that, never a confident one.
Open the current NDA notification and one past written paper. Answer the four questions from it: what form, what the marker pays for, what a miss costs, how many minutes a question buys. Then ask someone who does not know you to run one follow-up question on your own record, out loud.
I already interview well naturally. The board will take care of itself.
The board marks what a stranger, watching live, can see under a hard follow-up — and it weighs as much as the whole written paper. Natural ease reads differently under that kind of scrutiny. Rehearse it with someone who does not know you, the same as any other room you would prepare for.
NDA: check the current notice
As read on 14 September 2026, in the Union Public Service Commission’s own Notification for the NDA and NA Examination-II, 2026 (upsc.gov.in), dated 20 May 2026. The Commission changes these numbers each year; the shape does not. Confirm in the current notice: the number of questions on each written paper, not stated in this notification. Also confirm how many times the exam runs in the year you are reading this for.
