How To Prepare Environment UPSC Prelims and Mains

There is a significant overlap in the syllabus with Geography, Science & Technology as well as current affairs. Hence, if you cover the syllabus of the environment and ecology part well, then surely, you’ll have an edge in the other subjects as well. Here’s the preparation strategy devised by Gallant IAS experts:

  1. Read the syllabus: Go through the syllabus of the particular subject and try to learn it so as to map the topics in your mind. By doing so, you will be able to filter out irrelevant study material and keep your preparation focused. 
  2. Glance through PYQs: PYQs will give you a basic understanding of the level of the questions that are asked which will help you in selecting your resources very judiciously. 
  3. Read Biology NCERT Class XII: The last four chapters from this book covers all the basic and foundational level concepts concisely. So, reading them would introduce you to some terms that can come in the exam.
  4. Current Affairs: Current affairs are another important area with respect to environment and ecology topics. Read editorials from the Hindu and articles from monthly magazines like Yojana and Kurukshetra and prepare notes from them. Next, keep revising them to retain the concepts.
