This page contains the complete year-wise collection of UPSC Civil Services Preliminary Examination Previous Year Questions from 2013 to 2025. For each year, three resources are available for both GS Paper I (General Studies) and CSAT Paper II: a detailed Q&A & Analysis document by Legacy IAS Academy faculty, the official UPSC question paper, and the official UPSC answer key.

How to use: Use year-wise papers as timed full mocks in the last 2–3 months. Start with the most recent 3 years (2023–2025) to understand current trends, then go back systematically. Do not start year-wise mocks at the beginning of preparation — study subjects first, then test with full papers.
