Hi everyone,
My question is pretty straight forward. With my gmat fast approaching (10 days left!), I am wondering whether I'm ready or should postpone it... I've taken different exams (Kaplan, 800score, Princeton, gmatPrep, etc) for the last few weeks and my scores vary from 680 to 520

depending on the test... I just don't get it....
I am aiming for 680 or above. I've been studying for over 3 months now, and have done all the questions in the OG, Kaplan and Kaplan 800 books and can answer 80-90 percent of the questions correctly. I am taking a week off from work in order to practice some more, but am not sure this will be sufficient. So I was wondering how those who had already scored a 700+ knew that they were ready.
So, how do you know??
And, while I'm at it... do you think one week intense studying can really make a difference at this point?
Thanks a lot and have a great day/evening!!
