Hi Arun,
Thanks for writing in. As you may know, Indian males with IT backgrounds are very heavily represented in the application pool so it will take a very unique story to break out from your peers. You will need to explain very clearly why you want to move from IT to healthcare and why it's a logical fit for your skills. I wouldn't rely on your IT background bringing much of an advantage in terms of diversity, unfortunately.
Every school will publish their average GMAT score on their web site, so it's easy to find. At a cursory glance your GMAT will likely be more competitive at Minnesota and Alabama, compared to the other schools.
Good luck!
Daniel Richards
