Best Books for UPSC IAS Prelims 2026-2027 | Topper-Recommended Book List

Introduction

The UPSC Civil Services Examination (IAS/IPS/IFS) is widely regarded as the toughest and most prestigious competitive exam in India. Every year, over 10 lakh candidates apply, but only around 1,000 are finally selected for IAS, IPS, IFS, and other Group A Central Services. The first hurdle is the Prelims — a two-paper objective test that acts as a filtering mechanism for Mains.
