Both the courses MBA in finance and ICWA are very good . These have a very good career opportunities and scope .

MBA course :
Teach students about management.

Help in grooming the personality.

Opportunities:
Personal Financial Adviser
Financial/Securities/Investments Analyst
Credit Risk Management Analyst
Portfolio Manager
Financial Research Analyst

ICWAI course :
It is a professional course about accounts only.

It will teach students about profession of Cost & Management , account and tax function.

Opportunities:
Finance Manager
Cost Controller
Internal Auditor
Financial Controller
Accountant etc

In my opinion ICWAI is better if a candidate not get admission in a top MBA institute because doing MBA from an average institute will not give better career opportunities .
