UPSC Prelims Answer Key 2026

The UPSC Civil Services Preliminary Examination (often called UPSC Prelims) is the first stage of the Civil Services Examination conducted by the Union Public Service Commission (UPSC). This exam serves as a screening test for the UPSC Civil Services Main Examination. Successful candidates in Prelims become eligible to appear for the Mains examination, which ultimately leads to recruitment for prestigious services like IAS, IPS, IFS, and other Group A and Group B central services. The Prelims exam consists of two objective-type papers—General Studies Paper I and General Studies Paper II (CSAT). The answer key is released by UPSC typically within 2-3 weeks after the conduct of the examination, allowing candidates to evaluate their performance and estimate their scores before the official result declaration.
