Questions from Science and Technology are asked in UPSC Civil Services Prelims General Studies Paper 1 as well as in Mains General Studies Paper 3 (GS3). 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.
Priority Areas for Science and Technology
Like other subjects, it is important to prioritize sub-topics inside science first. It can be seen that UPSC normally asks more questions from Biology than Chemistry or Physics. And even from Biology, more questions come from Zoology and Microbiology than Botany. So know well the topics like genetics, micro-organisms/diseases, physiology, etc.
From the Chemistry side, topics like Nuclear Chemistry is important. Physics questions though few in previous year question papers, revolved around day-to-day applied physics touching concepts like surface tension, capillarity, etc.
Technology is a more preferred area for Mains for question paper setters. Even for Prelims, the last 3-4 years saw many questions from the Technology area. All those gadgets and technologies currently in news can come in UPSC questions. Wi-fi, IPTV, 3-D Printing, Blue-ray disk, etc. were questions in Prelims/Mains in previous years. Technologies like Biotechnology and Space Technology deserves special mention for Prelims and Mains.
