Hi

If you want to clear UPSC then you can choose any subject or course  of your choice based on your interest for your graduation after your 12th

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

So  you are free choose any discipline of your interest after your 12th PCB for graduation like mbbs, bds,bsc etc, the additional benefit of courses like mbbs is that you will have have a plan B i. e a good back up  if you fail to clear UPSC in the worst case .

Also,

There are many who first do mbbs and then crack UPSC as well. Some of doctors/mbbs graduates who took UPSC and become an IAS are listed below

------------) Dr. Shena Aggarwal :– AIR 1 in the year 2011.

------------) Dr. Arpit Jain :– AIR 194 in the year 2013.
