Economics

You can enroll for post-graduation after completing your Bachelor's.

After BA in economics, you can go for courses like MA in economics, MA in Mass Communication (MMC), M.Sc in Advertisement & Journalism, Master of Business Administration (MBA), Masters in Applied Economics and MBA in Economics.
You can also go for certification courses like SAP training, Diploma in Share Trading and Investment, Company Secretary Advanced Post Graduate Diploma in Events, banking, finance courses, etc.

So simple, it's a school of economics and MBA will come under the school of management studies. MBA HR under the schools of management is totally different from the schools of economics.

Every line is a good line, depending on how much interested you are. So tell me which field interests you the most?

However, students should not be allowed to undertake two regular degrees at the same time, the committee held.
