How to Prepare for the UPSC UPSC GS Paper 3 Syllabus?

The UPSC General Studies Paper III Syllabus covers Economic Development, Technology, Biodiversity, Environment, Security, and Disaster Management in general. In this section, we have listed few subject-wise preparation tips to help you effectively cover the UPSC Paper 3 Syllabus for the Mains Exam.

Economics

  • Despite the fact that the themes in this area are unchanging, the questions are challenging and dynamic. The NCERT books can assist you to clear up your ideas and provide you with a fundamental understanding of these areas. After you've gone over the required NCERT chapters, choose a single reference book for in-depth research.
  • NCERT class X, XI, and XII for economics, as well as keeping up with the country's and world's economic situations through a regular daily, can help you prepare notes for the upcoming questions.
  • While practising mock papers, first grasp the fundamentals of the questions. When writing your response, you must first briefly explain the concept, followed by an in-depth study of how the concept is important to the country's current economic situation, as well as its significance and consequences on the lives of inhabitants from all walks of life.

Science and Technology

  • The science and technology section's basic subjects are also crucial for IAS prelims preparation. As a result, you can accomplish them all at once and manage your time accordingly.
  • For in-depth study, you must be aware of India's various achievements in science and technology, as well as notable people in these fields, dating back to ancient times.
  • For this topic, you should rely more on the internet because you will get the most up-to-date news and articles that will assist you in taking better notes.
  • Space technology and its recent advances, biotechnology, robotics, and how they are affecting human life all over the world are among the current affairs-based scientific questions.
  • You must become in the habit of looking at scientific topics from both an economic and a scientific standpoint. Keeping a regular eye on the most recent economic surveys can provide you with enough data to make your responses more substantial.
  • Environmental science will generate a variety of issues based on ideas such as biodiversity, climate change, wildlife and forestry protection, legislation and policies enacted for these purposes, pollution, and the effects of human activities on the environment. In a nutshell, environmental issues that are based on or caused by human activities are particularly relevant.

  • Cropping and its patterns in India are the primary topics, which can be prepared at a basic level using NCERT Geography books.
  • Another key topic for this part is agricultural product transportation, marketing, and distribution.
  • The questions are based on a combination of geography, economics, and technology. You must use this method while answering any question from this section and express your point of view from all three perspectives.
  • Topics related to farm subsidies should be examined analytically because responses and notes must be written suitably. Because the word restriction must be rigorously adhered to, the analysis must be concise and accurate.
  • A subtopic of agriculture is land reform. It has lately been in the news for a variety of reasons, making it a significant topic for the IAS Mains 2022 exam.
  • Land ceiling policies, tenancy reforms, various land reform movements, and contemporary legislation and laws are all key topics in the land reform area.
  • Food processing and associated industries, as well as fundamental concepts about how they work, where they are located, and how important they are, are required to answer the relevant section undecided.
  • Take an objective approach to these topics by thoroughly knowing the key phrases and acts. Focus solely on agricultural and geographical problems, as well as the effects of the economy on these factors, as this is a prevalent sort of inquiry in this paper.

  • You can uncover various case studies and examples to better substantiate the response by reading the newspaper every day and taking notes on all pertinent news.
