UPSC CSAT 2025 Answer Key Out

Though a qualifying paper, the CSAT (Civil Services Aptitude Test) paper’s level of difficulty has been significantly higher in past years. Candidates must score 33% (66 out of 200 marks) to qualify, but many candidates still cannot clear it due to the progressively difficult comprehension passages, logical reasoning questions, and quantitative aptitude questions.

Study IQ’s expert team has analysed and solved the CSAT paper to provide aspirants an unofficial, yet reliable answer key to allow aspirants to self-evaluate a bit earlier than the UPSC publishes their version.

How to Calculate Your UPSC CSAT Score?

To assess your performance using the answer key:

Count the number of correct answers.
For each correct answer, add +2.5 marks.
For each incorrect answer, subtract 0.83 marks (⅓ of 2.5).
Total Score = (Correct x 2.5) – (Incorrect x 0.83)

You must score at least 66.67 marks (33%) in CSAT to qualify. However, CSAT is only qualifying in nature and does not contribute to the merit list.

When Will the Official UPSC CSAT 2025 Answer Key Be Released?

The official CSAT 2025 answer key will be published by UPSC only after the entire exam process is complete, i.e., after the UPSC CSE Final Result 2025 is declared. This usually happens 8–10 months after the Preliminary Exam.

Visit the UPSC official website – https://www.upsc.gov.in
Navigate to the “Examination” > “Answer Keys” section.
Click on “Civil Services (Preliminary) Examination 2025”.
Download the CSAT Paper II PDF set-wise.

What If You Disagree with the Answer Key?

Should the candidates feel that a particular answer is incorrect in the official key, they can submit a representation to UPSC, within the period indicated (usually 7 days after publication). However, UPSC is rejecting representation to the Preliminary Exam answer keys as per the current practice. Representations are allowed for some exams such as CDS, NDA, etc. representation for only a specified period.
