Start by reading the official UPSC NDA & NA notification so you know the current stages, sections and marking scheme. Then take one full-length mock under real exam conditions to find your starting level. Your result page breaks every attempt down by section and topic, showing accuracy, time spent per question and the questions you skipped — use it to pick the two or three weakest topics for the coming week.

For each weak topic, revise the matching UPSC NDA & NA notes, then solve previous year questions on that topic to see how the examiner actually frames it. Return to sectional practice once accuracy improves, and take a new full mock every few days to check that the gains hold under time pressure. Keep a short error log of every question you got wrong and why — careless slip, concept gap or time pressure — and re-read it before each mock.

Everything on this hub is free. Exam details can change between notifications, so always confirm dates, eligibility and patterns on the official commission website.
