Government & Defence Entrance Exam

You should go for BA in IAS most of the questions are related to art subjects such as history, political, etc.

B.Sc. with history or political science will be a good option. The main parts of history and politics play a major role in civil service exams.

Some popular ones you can check include:
DDA Dehradun (Doon Defence Academy)
Edge Academy Kotak
Centurion Academy
Study campus Academy.

Yes, I think BA will be fine as there are multiple options for you as in you can:
1. Do Masters and then get into Teaching as a Lecturer in a College/University
2. Do B.Ed and become a School Teacher
3. Prepare for Various government. , exams and get a government job.
4. Crack UPSC-CSE
5. Learn some computer course and join some small firm.

Hi Sakshi, Good to know you want to become a UPSC officer but you must know that None of your graduation subjects will matter in the path of UPSC. The only thing that matters is you can opt for Civil Engineering as a subject but CSE is not available there as a subject. If you wanna know more comment here.
