I'm preparing for loco pilot tyre 1,and I want to know that how should I prepare for general science
General Science in the IAS prelims exam:
Go through NCERT textbooks and revise them thoroughly.
Stick to the basics only. Preparing from the NCERTs is enough for the core subjects. No need to study scientific concepts in detail.
The idea is to cover the portions as much as possible; you don’t have to get a doctorate in science.
Update yourself on the latest scientific developments happening in India and abroad.
Know the Nobel Prize winners for the year and their area of work.
Follow ISRO, DRDO, Ministry of Science & Technology websites, and news.
If any concept confuses you or you don’t understand it well enough from the NCERTs, look it up on the Internet.
Go through and practice previous year question papers.
If there is an event in India related to science, always go through the basic science involved in that area.
