BharatNotes ⚡ TL;DR
CSAT is qualifying at 33% (66.67 marks out of 200). Despite being qualifying-only, roughly 5–7% of candidates who clear GS Paper 1 fail CSAT — a preventable disaster. Reading comprehension speed and mental arithmetic under time pressure are trainable skills; 15–20 dedicated CSAT mocks are adequate for most aspirants.
CSAT Basics
- Paper 2 (CSAT): 80 questions, 200 marks, 2 hours
- Qualifying mark: 33% = 66.67 marks (rounded to 67 marks)
- Marks do NOT count for the merit list — only qualifying vs non-qualifying matters
- Each wrong answer: -0.83 marks (1/3 negative marking)
Who Needs to Take CSAT Seriously
Low risk: Engineering, science, or mathematics graduates who regularly solve quantitative problems. One practice run per month is usually sufficient to stay comfortable.
Higher risk:
- Arts and humanities graduates who have been away from mathematics for 3–5+ years
- Candidates with English reading comprehension challenges
- Anyone who has consistently scored 60–75 in practice CSAT mocks — the buffer above the cut-off is too thin
CSAT Section Breakdown
| Section | Approx. Questions | Skills Tested |
|---|---|---|
| Reading Comprehension | 30–35 | Speed reading, inference, vocabulary in context |
| Logical Reasoning | 20–25 | Analytical reasoning, syllogisms, Venn diagrams |
| Quantitative Aptitude | 20–25 | Class 10 maths: percentages, ratios, data interpretation |
| Decision Making | ~10 | Situational judgment |
Mock Strategy for CSAT
- Take 1 dedicated CSAT mock (full 2-hour, 80-question simulation) in the first month of serious Prelims preparation — this gives you an honest baseline.
- If baseline score is above 100/200 comfortably: 5–8 more mocks spread through preparation is sufficient.
- If baseline score is 70–90: increase CSAT dedicated practice; 15–20 mocks recommended.
- If baseline is below 70: treat CSAT as a core paper requiring daily practice — 30 minutes of CSAT daily (reading comprehension + quant).
Time Management in CSAT
- Comprehension passages: do NOT read the passage first — read the questions, then the passage with questions in mind.
- Quant questions: never spend more than 90 seconds on any question; mark and move.
- Budget 15 minutes at the end for revisiting marked questions.
