Civil Servant (IAS/PCS)

Dear Mohit,
A slightly confusing question. You must complete your Bachelors to pursue your Masters. LSE is extremely competitive so please work hard on your academics. As far as I know IAS exams have age limits, please keep a check on this and prepare accordingly. Having a degree from LSE plus the IAS clearance will give you a career boost no doubt.

Subjects will be same in prelims for all. You have to choose an optional subject for your Mains exam. Thus, if you are asking about the optional subject then I would suggest you to go for sociology and public administration.

After completing B.Com you can appear for civil services examination, you don't need to pursue any other course. You are advised to do self-assessment or ask your teachers for the same to check your readiness to appear for civil services examination, and if there are gaps, you may take external help in the form of coaching to crack civil services examinations

You cannot settle in abroad with a government job.

You can try to speak in English but if it is not possible from your end, you can speak in Hindi.

Oh, you might get any question in UPSC. Besides, the Hindu mythology is closely related to Indian History. It forms a great part of the Ancient Indian History part. I suggest you dig up some facts regarding Mahabharata and Ramayana.
I hope it helped.
Thanks.

Civil Services is one of the toughest examination in India beside JEE or CAT. Once you become IAS or IPS, you can become Joint Secretary within 16 to 18 years of service and also occupy all the top posts in government departments. Also, you can help frame policies and lead their implementation, which can impact country as a whole. After MBA you can get jobs with high salary but your impact will only be within your organization or organization interconnected with your firm but civil servant impact is much beyond.
