Book content
The content of the book is solid there is no doubt about that. The page quality could have been a little better along with the packaging. Overall I’m satisfied with the book. It’s a good book with minimum to zero errors.

Best For Aspirants
As an aspirant, I’ve explored many PYQ compilations — but Disha’s book truly stands out. It’s not just a collection of past papers; it feels like a roadmap of UPSC’s evolving mindset. The arrangement is crisp, explanations are concise yet insightful, and the trend analysis makes revision smarter, not harder. What I liked most is how it bridges the gap between question and concept — helping me understand “why UPSC asked this” rather than just “what was asked.”If preparation is a journey, this book feels like the GPS guiding you through it. Simple, structured, and strategy-driven — Disha has definitely raised the bar for serious aspirants.

Really – Errorless
I am ready this book very frequently, most of my mate have been talking about this lately.What I feel with this is, its claim of being Errorless is something which makes it very unique.Just one thing I would request the author/compiler/publisher to break down the content in topic-wise format in order to make it more easy to use for beginners as well.I vouch for this book..Thank you, Disha, Mr.Mrunal.

Recommend to buy
Very good condition. This errorless version is splendid and I also noted that they added sources of the question and answers which is surprising. They did a very good job on organising and compilation.
