I am in a great dilemma. Actually as the first attempt I scored 710(Q49,V36) in 2015. The colleges I am targeting ask for higher scores. So I am re-taking the GMAT and this would be my 3rd and last attempt. However, I am afraid if my scores drop below 710 should I keep the score or cancel it?
I can reapply with 710 to those schools with some improved application but a new 700 or 690 would again diminish my chances. I understand that the colleges take highest scores but I think that theory is flawed because when a college(scpcly IIMs) when they see a lower, latest score they become skeptical.
So please help me chose.

I hope not. Schools should be more aware than almost anyone else that GMAT scores can vary for a number of reasons and that there is no reliable way to "discount" a score on the basis of another score (or on the basis of anything else, for that matter).
