How to use CSAT PYQs
Sit at least three recent papers with a timer. Track accuracy by bucket: reading comprehension, logical reasoning, numeracy. If numeracy collapses, return to Class 8–10 arithmetic rather than buying a thick CSAT manual.
- Do not postpone CSAT until after GS is “finished”
- Practise sets you will skip in the hall so you know your skip rules
- Re-check the qualifying percentage in the latest notification — do not rely on memory of an older year
FAQs
Is CSAT counted for the Prelims merit list?
No. Paper II is qualifying. Paper I marks decide the Prelims cut-off among those who qualify CSAT, as per the notification in force.
What is the CSAT qualifying mark?
In recent years UPSC has required 33 percent in Paper II. Confirm the figure in the latest CSE notification; do not treat a forum post as the rule.
I am from a humanities background. Can I still clear CSAT?
Yes if you practise under time. PYQs show that comprehension and reasoning carry a large share. Numeracy is usually school-level if you keep a weekly slot.
Is the 2024 CSAT answer key here?
The 2024 paper is hosted. A hosted key for 2024 is not. Use the official UPSC key when published.
