Hii Akshaya,

Hope you are doing well.

Ok, let me tell you candidates from any field of graduation is eligible for the UPSC examination, be it science or humanities. Academic career and interest should not be compromised for an uncertain and highly competitive career in civil service. You should always go for the field you are interested in, because you need only graduation degree from well recognised University. Specifically in subject doesn't matter.
But, If you find physics or chemistry really preferable please go for that. I feel that a good science student has greater flair and ability to write precise answers in a logical and objective manner.

If not science, then most probably you can prefer Bachelors' degree in Arts majorly in Political science or sociology or public administration.

Other eligibility criteria you should be knowing, still let give you some info:

Nationality: Indian (IAS and IPS)

As said before graduation from any recognised University is acceptable.

age limit: 21 to 32 years(relaxation according to the category)

Attempts: 06 (General and EWS) ; 09 (OBC); SC/ST (Upto age limit)

Height: A minimum height of 165 cm for men and 150 cm for women. The minimum height is relaxable to 160 and 145 cm for men and women respectively

Hopefully I'm able to clear your query.

best wishes ahead.

Hi

You can choose any subject or course like BA, Btech, Bsc, bcom, Mbbs etc based on your interest for your graduation/degree

This is because,

to be eligible for UPSC  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 and 21- 32 years old . You can check upsc eligibility criteria at https://competition.careers360.com/articles/upsc-ias-eligibility-criteria/amp

But yes ,

When it comes to upsc preparation and if you are totally focused towards it  then ,

choosing BA can be really helpful for your UPSC  examination, this is because in BA 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

Some of the best graduation courses regarding upsc are :-

----------)  BA Public Administration –   Highly relevant,  it has compact syllabus, it has a lot of overlaps with your polity & governance part in your GS II.

----------)  Ba     Sociology – it's   study of society, lots of material are useful  in GS I, Essay, in Ethics paper as well.

----------)   BA     History   – useful for prelims and your GS I.

----------)   BA Geography   -relevant for both prelims and GS

----------)  BA Political Science   – relevant for both prelims and GS II

Some other options are are BA Economics,BA Philosophy etc.

So, take your time and decide.

To help you further, here's a brief of your UPSC examination pattern

Your UPSC civil services examination consists of three stages

********prelims exam :- it is objective paper and is of qualifying nature , so you just  need to at least qualify it to be eligible for mains examination, the score /marks obtained by you in your prelims examination is not added up or used in your final merit. Your prelims exam consist of 2 papers: -

-----) general studies  1

-----) general studies II ( csat )

You get 2 hours for each paper

********Mains exam. :- it is descriptive /written examination . There are a total of 9 papers  which are listed below:-

-----) compulsory indian language.

-----) english

-----) essay

-----) general studies I

-----) general studies II

-----) general studies III

-----) general studies IV

-----) optional I

-----) optional II

The compulsory indian language and english are qualifying in nature . You just need to qualify them. The marks obtained by you in these two papers will not be counted towards merit list.

*********Interview :- After qualifying mains, you have to go through interview round, and it is more of test of your personality rather than knowledge.
