How to use Prelims previous year questions

UPSC repeats themes far more often than it repeats questions. Solving the last ten years subject-wise shows which parts of the syllabus get asked (Environment, Polity and Economy dominate recent papers), how statement-based questions are framed, and how elimination works on "how many of the above" options. Attempt each year as a timed paper first, then revisit the subjects where you lose marks.
