IAS Preparation

IAS Preparation

Welcome to the BYJU’S Civil Services Hub. Preparing for the prestigious UPSC Civil Services examination is a demanding yet deeply enriching experience. It is an examination that aims to choose the best talent for a career in public services of the Union of India. Clearing this exam will enable candidates to embark on a very rewarding and satisfying career in the service of the nation.

Aspirants, who begin their IAS preparation journey, naturally find themselves having many questions and few answers. They are usually in search of the best IAS coaching study material.

Common questions by IAS aspirants include:

  • How do I start my UPSC preparation?
  • What are the Study Materials for GS preparation for IAS?
  • How do I choose an optional?
  • Is one year enough to clear this exam?
  • How do I cover current affairs when the IAS preparation syllabus is so vast?
  • Where to download UPSC study materials/IAS study material PDF?
  • Is self-preparation for the IAS exam enough to clear it? 

In fact, a good period of 3-4 months of valuable study time can easily be wasted away if such questions are not answered at the beginning of a preparation cycle.
