Science and Technology for UPSC

Hello dear aspirants,

Are you an IAS aspirant? If the answer is ‘Yes’, you must not take the subject of science and tech for granted. Don’t think that we should read this subject only to clear our exam, we should love this subject because the science of today is the technology of tomorrow. This is the way of our future. This is the only process that takes us from confusion to understanding in a manner that’s precise, predictive, and reliable, a transformation for those lucky enough to experience it. And that is empowering and emotional.

After mentoring 5000+ students, we feel that science and technology is a pain for non-science background students. Acknowledging this and removing all difficulties, we, the Civilsdaily senior IAS mentors team have prepared a workable strategy and booklist for this subject. Let’s have a look…

Science and Technology in UPSC

There is a good weightage of Science and Technology in UPSC-CSE.

  • In Prelims, 12 to 16 questions are asked every year.
  • In Mains, 25% of GS-3 consists of Science and tech questions.

So, taking this subject lightly may cause disaster. 


How to prepare for Science and Tech for UPSC

This is the 2nd most unpredictable and complicated subject in the UPSC syllabus. Average 15 questions you can expect and 15 out of 100 MCQs truly matter when it is the UPSC-CSE prelims.

How to deal with Science and Technology:

There are 2 sections

  • Science and Technology (relates to Current development)
  • General Science (Biology, Human Health, Physics, and Chemistry in daily life.)

Now the question is which one of the above sections is more important!

Analyzing the previous 5 years’ question papers, it’s clear that the majority of the questions come from Science and Technology (relates to Current development). But, because of the super dynamic nature of UPSC, we should prepare both sections smartly.
