The Civil Services Aptitude Test (CSAT), or General Studies Paper II, is a qualifying paper in the UPSC Prelims. Although you only need 33% (66 marks out of 200) to pass, its increasing difficulty level has made it a major hurdle for many aspirants. Here is the ultimate strategy to master it.
1. Reading Comprehension (RC)
RC forms about 30-35% of the paper. The passages in UPSC are often dense and based on philosophy, economy, or environment.
- Strategy: Do not use outside knowledge. Answer strictly based on what is provided in the passage. Understand the difference between ‘Inference’, ‘Corollary’, and ‘Crux’.
2. Logical Reasoning & Analytical Ability
- Key Topics: Syllogism, Blood Relations, Direction Sense, Seating Arrangement, and Clocks/Calendars.
- Strategy: These are the most scoring sections. Practice drawing Venn diagrams for syllogisms and visualize seating arrangements step-by-step.
3. Quantitative Aptitude (Basic Numeracy)
- Key Topics: Number System (Highly crucial), Percentages, Profit & Loss, Time & Work, Speed Distance & Time, and Permutation & Combination.
- Strategy: UPSC relies more on logic rather than complex formulas. Master the basics of Number Systems (divisibility rules, remainders) and LCM/HCF.
