CSAT Answer Key 2025 is a crucial resource for candidates who appeared in the UPSC Prelims examination. Through CSAT Answer Key allows them to evaluate their performance in General Studies Paper II (CSAT) and estimate whether they are likely to clear the qualifying cut-off. The official CSAT answer key will be released by the UPSC on the official website, upsc.gov.in, once the exam cycle is over. However, an unofficial answer key will be provided here by PWOnlyIAS.
Here we have provided details of UPSC CSAT Answer Key 2025, including expected release date, how to download, and access to previous-year CSAT answer keys for your reference.
The UPSC Prelims CSAT (Civil Services Aptitude Test) 2025 was conducted in the second shift (2:30 PM to 4:30 PM) on 25 May 2025. The UPSC CSAT Answer Key 2025 (Unofficial) was released after the Prelims exam on the same day by the PWOnlyIAS Academic Team.
Until the official key is published by UPSC—which happens only after the final result of the exam cycle—candidates often rely on provisional answer keys provided by PWOnlyIAS academic experts.
