The Civil Services Aptitude Test (CSAT) is a qualifying paper in the UPSC Prelims exam. It tests students on reasoning, comprehension, and numerical ability. Even though it is only qualifying in nature, students should not take it lightly. Proper preparation is essential to ensure that they score the required 66 marks out of 200 to clear this paper.

How to Prepare for CSAT Overview

The Civil Services Aptitude Test (CSAT) was introduced in 2011 as part of the Preliminary examination, the first stage of the three-stage selection process. CSAT comprises three key sections: Reading Comprehension, Quantitative Aptitude (Mathematics), and Logical Reasoning. To prepare effectively, students should thoroughly understand the syllabus, practice consistently, and take mock tests. A structured, step-by-step approach is essential for success.  

CSAT evaluates candidates on logical reasoning, analytical ability, decision-making, and problem-solving skills. It is a qualifying paper, requiring only 33% marks to pass. The exam carries a total of 200 marks, and candidates must score at least 66 marks to qualify.

How to Prepare for CSAT, CSAT Prelims Strategy

To tackle CSAT Prelims 2026 efficiently, students should adopt a step-by-step approach:

  • Understand the Exam Pattern and Syllabus: Reviewing the syllabus and previous years’ question papers helps students identify important topics and question trends.
  • Enhance Reading Comprehension Skills: Since comprehension carries significant weight, students should regularly read newspapers like The Hindu or The Indian Express to improve reading speed and analytical ability.
  • Strengthen Basic Mathematical Concepts: Those without a strong mathematical background should begin with foundational topics such as percentages, ratios, and averages. NCERT books and RS Aggarwal’s Quantitative Aptitude are excellent resources.
  • Develop Logical and Analytical Thinking: Logical reasoning requires consistent practice. Engaging with puzzles, patterns, and reasoning exercises from books like RS Aggarwal’s Logical Reasoning can be beneficial.
  • Practice with Previous Year Papers; Solving past papers helps in understanding question trends, difficulty levels, and repeated topics.
  • Attempt Regular Mock Tests: Mock tests assist in time management and self-assessment. Various online platforms offer CSAT-specific test series.
  • Improve Decision-Making Skills: As this section has no negative marking, practicing case studies and situational judgment tests can boost scores.
  • Efficient Time Management: Students should attempt easier questions first to maximize their score within the allotted time.
  • Consistent Practice for a Qualifying Score: Even though CSAT is only qualifying, regular practice is essential to clear the 66-mark threshold comfortably.
