How to Prepare for Science and Technology for UPSC Exam

  • Start with the most basic concepts. The main idea is to understand the application behind the scientific concepts in order to answer questions related to that. You should begin with what the definition means and then what are the applications of the particular concept. Then you dive into the subtopics of a given topic.
  • For example, the Atom as a concept is a wide topic to cover. You begin with what it means, then the history, then various studies, and finally the application. This way you follow a particular flow covering everything.
  • The most important topics in the science and technology sections are – Human Body, Plant System, and Basic Physics Modules. These are very wide and must be understood from the core rather than just skimming the concept from above. Applicants must begin with elementary books for this subject.
  • After finishing the basics of the science as mentioned above, you get into details. Biotechnology, Atomic Theory, Animal and Plant Kingdom Phylums, and more are some next important topics in this subject. They are a bit complex and you must know the simpler concepts first to understand these in detail.
  • Lastly, read everything thoroughly from the beginning. Don’t take this subject lightly as this is the most complex subject of the examination. Give it an ample amount of time and effort to improve your result and qualify for the mains exam. Read all the topics in the syllabus and don’t make the mistake of leaving anything for the end.
  • NCERT is the best book to study for these particular subjects. It is because of the simple language and accessibility. Applicants from all around the country can access the books and prepare accordingly. You can refer to the list of NCERT Books for the UPSC exam for further details.
