Hello,
I just finished my engineering 6 months back. I have a very less score in my Bachelors. Is there any universities in US that intakes students with less academic scores and Gmat. I really want to do my masters and become an entrepreneur.

A lot depends on how you would like to use you entrepreneur MBA, i.e. what stream of business you would like to pursue. This can lead you to different schools and locations throughout the US. For example, you might want to choose a school in a city that has jobs in your field. As for good entrepreneurial programs, take a look at this article that lists some schools.

You can then look at their individual requirements to see if your GMAT score is sufficient.
