Science & Technology is one of the fairly important subjects with respect to both UPSC CS Prelims and UPSC CS (Main) examination. It is included in the GS III paper for UPSC CS(Main) and General Studies paper in Prelims.
Questions related to current developments in science and technology are asked in Prelims. However, it is important to have a theoretical understanding of the static syllabus of the subject in order to write effective answers in the UPSC CS(Main) examination. Let us look at the Science and Technology syllabus for UPSC along with the preparation strategy as well as the booklist.

Science and Technology is considered to be one of the abstract subjects that follow no fixed pattern or syllabus for both UPSC CS Prelims and Mains. However, the past year trend analysis clearly shows that questions from this subject are analytical in nature. Hence, the following strategy will be useful to kickstart your science and technology preparation for UPSC:
Strengthen your foundation : It is very important to have a crystal clear understanding of the basic concepts of the topics mentioned in the syllabus. Reading NCERTs from Class VI to X will introduce you to the basics of the subject.
Previous Year Questions : Since this particular subject is boundless, you need to stick to the syllabus while preparing for the Science & Technology portion. Hence, always keep a copy of the syllabus in front of you and check if the topic is mentioned in the syllabus.
Current Affairs : It has been observed that questions pertaining to current developments are often asked in UPSC CS Prelims as well as Mains. Hence, leverage editorials from the Hindu and the Indian Express to its fullest potential. Make small notes of the pointers for any recent development in the field of science. It includes space exploration missions, advancement in Artificial Intelligence, medications, reports surrounding spread of diseases and its containment using scientific methods, etc. Further, you should expect a lot of questions from Science & technology this year owing to the ever-changing advancements surrounding COVID crisis management. Hence, you should regularly read about the reports on vaccine testing as well as the virus spread across the globe.
Mock Tests : Solve a lot of mock tests and sectional tests. You can purchase Science & Technology Question Bank for Civil Services Examination by TMH publication for practicing the questions for Prelims.
Practice answer-writing : For mains, practice answer-writing as much as possible and get your answers evaluated by your mentors. For science & tech, it is important to follow a diagram-based approach as well as add factual information for making your answers more substantive.
