UPSC Prelims PYQ Book: GS + CSAT
All 2,880 Prelims questions, topic-wise, solved.
Stop guessing what UPSC will ask. Read what it has already asked.
Every one of the 2,880 Prelims questions from the last sixteen years, sorted topic by topic, explained in plain words, with the traps marked.
- 1,600 GS Paper I questions + 1,280 CSAT questions, none missing
- Topic-wise, mapped to the official syllabus, with answer keys checked against UPSC
- Repeat patterns from the 1990s that came back, flagged where they return
- Practice sets and OMR pages after every topic
You have read the books. So why does the paper still feel like a stranger?
Most aspirants lose Prelims not because they studied too little, but because they studied without the paper in front of them. Months go into notes that UPSC never tests, while the topics it returns to every single year get one quick reading.
This book turns that around. When you see sixteen years of questions on one topic on one page, the fog lifts. You notice which ideas UPSC loves, how it hides a wrong option, and where your own weak spots are. Revision stops being a ritual and becomes a plan.
The day you can predict the shape of a question before you read it, Prelims stops being a lottery.
See the pattern
Each topic opens with every past question on it, so the examiner's favourite ideas jump out in minutes.
Understand, don't memorise
Short explanations tell you why the right option is right and why the tempting one is wrong. That is the habit that wins elimination.
Test yourself
Original practice questions and OMR pages after each topic, with the key at the back. Know you are ready, instead of hoping.
