About Science & Technology PYQs
Although this appears to be a disorganized, purely current affairs based and a highly unpredictable subject, it is not like that. 1st thing, on average 11-12 question appear from Science & Technology. Thus, you cannot afford to neglect it, especially if you’re from a non-technical background.
Further, there is an order to the chaos. As listed below, there are definite topics /sub-topics in science and technology. With some being more important than others. As orange bars in the below diagram illustrate, first 3 topics i.e. A) Electronics & IT, B) Astrophysics & Space Technology and C) Biotechnology should be done very well.
