UPSC IAS General Studies Paper II: Section-Wise  Strategy

It is to be noted that GS-3 questions revolve around current affairs. So, for each topic mentioned in the syllabus, make concise notes. Restrict yourself to only a few best current affairs resources as in the end you have to write a 250-word answer for all the topics. 

Economy and Infrastructure

The topic has several sub-topics like planning, growth, employment, development and mobilization. Though the topics covered in this section are static in nature, the questions are tricky and dynamic. The key is to use a single reference book for in-depth studies after you have gone through the relevant NCERT chapters.

  • Stay updated about the economic situation of the country as well as the world. 
  • While appearing in mock tests, understand the basis of the questions asked from this section.
  • As much of the syllabus overlaps with GS Paper II, candidates need to look at the questions from the dual perspective- first from the perspective of polity and next from the economic views. However, the question in GS Paper III should be answered from the economics point of view. 
  • Have an objective type approach to these topics by learning the important terms and acts thoroughly. Exclusively focus on agriculture and geographical topics and the effects of the economy on these aspects which is a common type of question in this paper.
