Basic Science

General Science and Technology holds significant importance in the UPSC Civil Services examination, typically featuring around 10 to 15 questions in the IAS preliminary tests on an annual basis.

For those with a background in science or engineering, this section might seem easier in the UPSC exam. But with the right approach, anyone can tackle it. This part of the exam covers General Science and can be divided into four categories: Biology, Chemistry, Physics, and current scientific events and technology.

It includes various topics like the solar system’s formation, nuclear power, cell structures, human body functions, genetics, plant and animal classifications, reproduction, biotechnology, atomic theory, and energy-efficient lighting.

Preparing for this section involves understanding these categories and topics thoroughly, regardless of your background.

Key Points

Here are some key things to keep in mind while preparing for the IAS preliminary test in general science:

  1. Comprehensive Coverage: Ensure you cover all topics under Biology, Chemistry, and Physics thoroughly.
  2. Current Affairs: Stay updated on the latest scientific developments and technological advancements.
  3. Practice and Revision: Regularly practice questions and revise the concepts to solidify your understanding.
  4. Conceptual Clarity: Focus on understanding concepts rather than rote memorization. This helps in application-based questions.
  5. Mock Tests: Take mock tests to simulate the exam environment and assess your preparation level.
  6. Time Management: Allocate time effectively for each section to cover all topics adequately.
  7. Stay Relaxed: Maintain a balance between studies and relaxation to stay refreshed and focused.

Stick to NCERT Textbooks: Focus on fundamentals, revising them thoroughly. In-depth examination of scientific topics isn’t necessary.

NCERTs for Essential Topics: NCERTs are sufficient for crucial subjects. A science degree isn’t a requirement.

Stay Updated: Be aware of recent scientific advancements globally, including Nobel Prize recipients and their fields of study for the year.

Follow Science Organizations: Keep track of ISRO, DRDO, and Ministry of Science and Technology news.

Use Internet for Clarity: If any NCERT topic is unclear, use online resources for better understanding.

Practice IAS Questions: Review and practice previous years’ IAS questions for preparation.

Connect with Scientific Events: Whenever there’s a scientific event in India, revisit the basic science related to that field.
