Well, everyone has his or her own goal I guess. And that goal might vary greatly. I guess that I have every right to express my own feelings and opnions here. 720 in my eye, is really a so-so score for myself. And no offence, but I really found it difficult to decide whether to take GMAT again or not. That is the only reason that I put the note here. Nothing to show off. If I really want to show off, then the best way is to put a 760 or 780 score and complain about it.
P.S.: I am just in Beijing and Beijingers can also be very NN. Who said only ABC or BBC can be NN?!! Besides, I did lead a team of more than 50 college students once in a project:-))
