General Science For State PSC Exams 2022 | Best Book for Exams Preparation

General Science For State PSC Exams 2022 | Best Book for Exams Preparation: General Science and Technology is a subject that is equally important as other subjects for the UPSC, State PSC civil services exam. Every year about 10-15 questions are asked from this section in the prelims exams. So, you can assess the importance of this section. Generally, students from science or engineering backgrounds will find this section easy, while others who are from the non-science background may find this section a bit tough. 

Science and Technology are asked in UPSC Civil Services Prelims General Studies Paper as well as in Mains General Studies Paper. The science part deals with subjects like Physics, Chemistry, and Biology. The technology part deals with the application of various sciences. Questions can come from all the latest technologies like Biotechnology, Information Technology, Nano-technology, Space Technology, Defense Technology. Energy Technologies etc.

Like in every other subject, scout the newspapers and science magazines for the latest in scientific developments in India and abroad. As explained earlier, look for concepts involved in such events and developments.

If you get time, go back to school texts (at-least till Class X) to build your science basics. NCERT Biology Texts for Class 11 and Class 12 are also really good. Selective reading of these texts is advised. For the technology part, Science and Technology column from The newspapers is a good read.

And regarding books for Science and Technology! There is no book which can be called a panacea for science and technology.

This section can be classified into four:

  1. Biology
  2. Chemistry
  3. Physics
  4. Current affairs related to science and technology

Current Affairs Year Book 2022: General Science & Technology
