The book contains solved previous year questions ofUPSC Civil Services Preliminary Examination from 2011-2025d.The questions have been segregated subject-wise as well as topic-wise to make it more accessible for the students. The rationale behind including the questions starting from 2011 is the major shift in the pattern and difficulty level of the preliminary examination post- 2011. A compilation from 2011-2024 ensures that the questions are in-line with the latest trend of the exam.

There are three distinctive features that make this book stand apart from the existing options. First, the answers have been thoroughly verified with the official answer key of UPSC. Second, all the options have been explained comprehensively with special emphasis on conceptual clarity. Third and the most important distinctive feature is its futuristic approach through a section of “Additional information” for each question. The recent trend shows that UPSC often frames questions around the core theme and the options of previous year questions. The section of “Additional Information” is intended to make students future- ready for such types of questions.

The NEXT IAS team has put sincere efforts in preparing this valuable resource for students. I hope this book will stand upto the expectations of aspirants and my desire to serve the student community by providing the best study material will get accomplished.
