710 is defenitely a good score. Don't get disappointed at all. Since you have time - may be you should work on other parts of your application. In my view securing MBA from any of the top programs is the same. It is more important to have a Goal and get into a program that will help you help you achive your Goal. My 0.01c.
Still go and party dude. Be proud of your achievements.
"To dream anything that you want to dream, that is the beauty of the human mind. To do anything that you want to do, that is the strength of the human will. To trust yourself, to test your limits, that is the courage to succeed."
