I've been studying for the GMAT since mid-February when I started a Kaplan prep course, and am now just 6 days away from exam day. I think the course has been helpful in terms of the online resources it provides (A LOT!), but I quickly realized that Kaplan exams/questions were much harder than normal, so I quickly purchased the OG 11, Princeton Review manual, and the Manhattan SC guide. I've completed 80% of it. I've limited my practice exams to the exams assigned for homework through the Kaplan course, and I've taken 1 to 2 every weekend, in addition to the independent work I did outside of the course. So far, my highest Kaplan test score is a 640. My Kaplan practice test scores have been the following:

600 (paper diagnostic)
600
630
580
530
540
640

I have 4 days off before the exam and plan to take at least 1 exam a day, including the 2 GMATPrep tests, which I purposefully saved for taking just a few days before exam day.

I'm shooting for a score above 700. Can I score above 700? Any advice would be greatly appreciated.
