How to Calculate UPSC Prelims Score
Candidates can calculate their expected score by counting correct and incorrect answers separately.
GS Paper 1 Score Formula
Estimated Score = Correct Answers × 2 – Wrong Answers × 0.66
Example for GS Paper 1
Suppose a candidate has:
- Correct answers: 60
- Wrong answers: 10
Then:
60 × 2 = 120
10 × 0.66 = 6.6
Expected Score = 120 – 6.6 = 113.4 marks
CSAT Paper 2 Score Formula
Estimated Score = Correct Answers × 2.5 – Wrong Answers × 0.833
CSAT is qualifying in nature. However, candidates must clear it to move ahead in the UPSC selection process.
UPSC GS Paper 1 Answer Key 2026
The UPSC GS Paper 1 Answer Key 2026 is very important because GS marks help decide the Prelims result. Therefore, candidates should calculate this paper’s score carefully.
GS Paper 1 usually includes questions from:
- Indian History
- Geography
- Indian Polity
- Economy
- Environment
- Science and Technology
- Current Affairs
- General Awareness
Since GS Paper 1 plays a major role in the result, candidates should match every answer with care.
UPSC CSAT Answer Key 2026
The UPSC CSAT Answer Key 2026 is for General Studies Paper 2. Although CSAT is qualifying, candidates must clear it.
CSAT usually includes questions from:
- Reading comprehension
- Logical reasoning
- Analytical ability
