Overview of UPSC Reasoning Aptitude Paper 2 Exam

UPSC Civil Services Preliminary Examination consists of two papers:

  • Paper 1: General Studies (GS)
  • Paper 2: Civil Services Aptitude Test (CSAT)

While Paper 1 determines merit for selection to the Mains examination, Paper 2 is qualifying in nature, requiring candidates to secure a minimum of 33% marks. However, despite being qualifying, CSAT has proven challenging for many aspirants due to its focus on logic, reasoning, comprehension, and numerical aptitude.

The CSAT paper evaluates a candidate’s intellectual abilities rather than factual knowledge. It tests how effectively a candidate can process information, solve problems, and make decisions under time constraints.
