The IAS Preliminary Examination conducted by UPSC in 2021 had two papers – General Studies Paper I and CSAT Paper II. CSAT, short for Civil Services Aptitude Test, is also known as General Studies Paper II and is qualifying in nature. The CSAT Paper II 2021 PDF includes 80 questions covering comprehension, logical reasoning, analytical ability and basic numeracy. Despite being a qualifying paper, many aspirants found the 2021 paper unexpectedly tricky and lengthy, making it one of the more challenging years.
I am writing this article because year after year, candidates get caught off guard by CSAT. Many put all their effort into GS Paper I and neglect CSAT assuming that basic preparation is enough to qualify. But with increasing complexity in recent years, especially in comprehension and reasoning, even engineering graduates have found this paper tough. The 2021 paper is a good example of how UPSC is testing not just aptitude, but also time management. Sharing the CSAT 2021 paper helps aspirants assess the level of difficulty and fine-tune their preparation for upcoming attempts. It’s always better to learn from the past and plan smarter for the future.
What is CSAT in IAS Prelims?
The Civil Services Aptitude Test, or CSAT, is General Studies Paper II in the UPSC Preliminary Exam. Unlike Paper I, it’s qualifying in nature. You need to score at least 33% (i.e., 66 marks out of 200) to qualify. However, failing to do so means disqualification from the mains, no matter how well you perform in Paper I.
CSAT Paper II Key Highlights:
- Total Questions: 80
- Marks: 200
- Duration: 2 hours
- Negative Marking: ⅓ of the marks for each wrong answer
- Qualifying Marks: 66

Reading comprehension sections were lengthy and filled with abstract language. The maths section was not advanced, but the wording made it harder than it looked. The paper tested not just aptitude, but also stamina and presence of mind under pressure.

Final Thoughts
The CSAT Paper II of 2021 is a strong reminder that this paper cannot be taken lightly. Even if it’s qualifying, failing it will stop you from moving to the Mains stage. Treat CSAT like any other paper—give it regular practice and work on your weaknesses. Use the 2021 paper to understand the trend and plan your preparation accordingly. Practise at least 2–3 full-length CSAT papers before the prelims so that you’re not caught off guard like many were in 2021.
