I am a 12th commerce student which subject I have to choose for preparation of civil services
Hi
You can choose any subject or course of your choice based on your interest for your graduation
This is because,
to be eligible for UPSC or the IAS examination there is no compulsion to be a graduate in a particular subject, all you need to be eligible is that you should be a graduate in any discipline
So you can choose any stream of your interest, but yes if you are interested in Arts then
choosing Arts or the humanities can be really helpful for your UPSC examination, this is because in Arts you will be learning subjects like history , polity etc which are a part of the UPSC syllabus so it will help you in your upsc examination.
Thankyou
