Hello,

Yes you can take any programme for your Bsc.

The only requirement is to have a degree from proper university and good marks. You should have completed your graduation before applying for IAS and should meet the basic requirements for UPSC.

Start your preparation from early stages itself and get the details of UPSC exam.

Thank you

There is no such provision of undergraduate course for the UPSC cse exam.

You can study any  course in your undergraduate. You just need a degree from a proper accredited college from the government. Whether you do b.Sc maths or BA political science it doesn't matter.

All the best!!
