Hello,

There is no such thing as best degree when it comes to appearing in UPSC exam, the reason being the eligibility criteria itself states candidates from any stream of graduation from a recognized university are eligible to apply, even final year students are also eligible , candidates need to attain 21 years as on 1st August of appearing year, now UPSC tends to be more humanities oriented in the sense if you look at the syllabus it's mostly comprised of humanities subject, so having a graduation in subjects like Political science, public administration, history,economics, geography etc help to a large extent ,because there is considerable overlap with general studies as well as optional subjects, now you can appear in UPSC with or without back up plan, so being a science student if you have aspirations in your field you can go ahead with this choice, the toppers of UPSC come from diverse backgrounds such as medicine, engineering, commerce etc, so as per your interest you can go ahead with whatever choice you have, remember that irrespective of the stream the diligence, single minded focus, dedication and perseverance remain the same for every UPSC aspirant.
