Do u want to give IFOS EXAM ???

Hello Shubham,

It's totaly alright ,as the eligibility criteria for the UPSC Exam is only 

the candidate should have gained a graduation degree from a recognized University.

As you are thinking to do B.sc (H) in computer science ,then you have also 

chance to make your career in the IT Field.

Thank You.

Hope it helps.

Hello student, Greetings from careers360.com!
Yes,you may go with the subject of your choice. UPSC offers about twenty five optional subjects including the literature of the regional subjects, which you can opt for during the exam. The main eligibility is a Bachelor's degree and one should have completed 21 years of age at the time of appearing for the exam.

Good luck!
