i scored 83.54 in CAT 2010.i am M.Tech (power systems) working in a PSU .my aim is to become successful entrepreneur.Whether Distance learning MBA will be of any use ?

To be entrepreneur no degree can help except you strong will, Fromm IIM only few are but from MIT / Harvard big number. Just don't waist time just make your project and start your work. Birla , Dhirubhai , Bill Gates , Dell and other top Entrepreneur are not MBA
