B.A

In my opinion, you should complete your B. Tech. IAS is very hard to reach. So, in case, if you can't get IAS, then your B. Tech degree will help you. Be practical. Best of luck for future !

Do your PG in Economics as its very good career option. Economics graduates have various professions open to them. . they can work in various sectors like Business, Education, Government & Consultancy fields. Apart from these there are job opportunities in Banking, Political consulting and various Nonprofit organizations. Give your best and try to get admission in any of the top colleges to study this course like DSE Delhi, UPES Dehradun, JNU, BHU etc. These provide strong curriculum, faculty and placements.
