The UPSC offers physics as an elective subject for the IAS exam. It is a fundamental science subject that should only be chosen by engineering or physics graduates. It should be noted that physics can be a rewarding subject if prepared adequately and methodically, despite the fact that there is essentially no overlapping with the General Studies paper. The curriculum for physics for the IAS exam is appropriate for students who’ve already studied physics at the college level. Physics is a highly technical discipline. Statics and dynamics, relativity, thermodynamics, quantum theory, magnetism and electricity are among the topics included in this subject’s IAS exam curriculum.
There’s no room for interpretation because this is a scientific and logical subject. Nothing is opinionated, therefore if you correctly compose your response, you should receive marks for that. It is a subject that can be scoring because diagrams and visual representations can earn you marks. There are additionally numerical questions here that, if answered correctly, would get you the highest marks.
If you already have a strong foundation in this subject, you should choose this optional since you can improve your final UPSC exam score by doing well in the two elective papers.
