Dear aspirant !

Hope you are doing well ! You should first focus on class 12 , make good percentage it will boost your confidence.

Then ,

1. Read more about civil services. ...
2. Take up a graduation course that involves history and polity. ...
3. During your graduation, study these subjects well keeping in mind the UPSC syllabus...

Go through the upsc syllabus first , watch the interview

And dont be a part of rat race ,give time to explore yourself and then decide to prepare for upsc. It is not a cup of tea for everyone

Hope you understand !

Thanks
