Target Schools:-

Which among these are ambitious, within reach and safe.
What are the prospects of getting an admit into other B-schools outside US like insead,IE spain, LBS
Can I add anything else to my profile to make it more appealing

Also, what are my chances at ISB Hyderabad.

There were some technical issues at the exam centre which hampered my score a bit so I'm also considering giving gmat again to get a score around 750. I used to get 750-760 in my practice tests.

Thanks a lot
