CSAT Preparation Guide: How to Clear UPSC Paper 2 Easily
CSAT (Civil Services Aptitude Test) is Paper 2 of UPSC Prelims. Many aspirants fear it. But with the right approach, it's actually the easier paper.
This guide will help you clear CSAT without stress.
Understanding CSAT
What is CSAT?
CSAT stands for Civil Services Aptitude Test. It tests your:
- Reading ability
- Logical thinking
- Basic math skills
- Decision making ability
CSAT Structure
| Aspect | Details |
|---|
| Total Questions | 80 |
| Total Marks | 200 |
| Marks per Question | 2.5 |
| Negative Marking | 1/3rd (0.83) |
| Time | 2 hours |
| Qualifying Marks | 33% (66 marks) |
The Big Relief
CSAT is only qualifying! Your CSAT marks don't add to your merit. You just need 33% (66 marks out of 200).
This means:
- Answer 40 questions correctly = 100 marks = SAFE
- Even 30 correct with 10 wrong = 75 - 8.3 = 66.7 marks = PASS

- Answer based on passage, not your knowledge
- Don't assume anything not written in passage
Common Mistakes:
- Adding your own opinions
- Selecting answers based on general knowledge
- Reading too fast
- Not reading all options

Common CSAT Patterns
Comprehension Patterns
Pattern 1: Direct Questions
"According to the passage, what is X?"
→ Answer directly from text
Pattern 2: Inference Questions
"It can be inferred from the passage that..."
→ Think beyond literal meaning
Pattern 3: Vocabulary Questions
"The word 'X' in the passage means..."
→ Use context to determine meaning
Pattern 4: Main Idea Questions
"The passage is mainly about..."
→ Think about overall theme
Reasoning Patterns
Pattern 1: Series
2, 6, 12, 20, 30, ?
→ Differences: 4, 6, 8, 10, 12
→ Answer: 42
Pattern 2: Coding
If APPLE = ZKKOV, then MANGO = ?
→ Each letter moves back by 5 positions
→ Answer: HZJXL
Pattern 3: Direction
A walks 10m East, turns left, walks 5m...
→ Draw diagram
→ Find final position
Math Patterns
Pattern 1: Percentages
If 20% of X is 40, find X
→ X = 40 × 100/20 = 200
Pattern 2: Ratios
If A:B = 2:3 and B:C = 4:5, find A:C
→ Make B same: A:B = 8:12, B:C = 12:15
→ A:C = 8:15
Pattern 3: Data Interpretation
Tables, graphs → Read carefully → Calculate
Mock Test Strategy
How Many Mocks?
- Start CSAT mocks: 6-8 weeks before Prelims
- Frequency: 1 mock per week initially
- Last month: 2-3 mocks per week
How to Analyze?
After each mock:
- Calculate section-wise score
- Identify weak areas
- Analyze wrong answers
- Note time taken per section
- Make improvement plan
Target Scores
