UPSC Prelims Pattern: What Your Mock Must Copy
| Paper | Questions | Marks | Time | Negative marking | Nature |
|---|---|---|---|---|---|
| General Studies Paper I | 100 | 200 | 2 hours | −1/3 of the marks for that question (−0.66) | Decides merit for Mains |
| CSAT (GS Paper II) | 80 | 200 | 2 hours | −1/3 of the marks for that question (−0.83) | Qualifying: 33% (66 marks) |
The cut-off is decided only by GS Paper I, but failing to score 66 in CSAT disqualifies you regardless of your GS score. Every mock plan must include CSAT.

How to Analyse a UPSC Prelims Mock
- Sort every question into three groups: knew it, eliminated to an answer, pure guess.
- Calculate your guess accuracy. If fewer than 1 in 3 pure guesses is right, stop guessing blindly (the −0.66 penalty will outweigh the gain).
- Make a source list for every question you got wrong: NCERT, standard book, newspaper or a government report.
- Revise the topic, not just the question. UPSC rarely repeats questions but often repeats themes.
- Track your score trend, not single scores. A steady rise matters more than one good test.
