The best way to approach Prelims PYQs is topic-wise, not year-wise in the beginning. Pick one subject, solve 10–15 questions at a time, and identify patterns in how UPSC frames options. This builds conceptual clarity instead of random familiarity.

Don’t just check the right answer — analyse why other options are wrong. PYQs train your elimination skills and help you understand recurring themes, traps, and keyword-based questions.
Finally, use PYQs for revision. Revisit the same questions after a few weeks and test your recall. When previous year questions start feeling predictable, your preparation is moving in the right direction.
