Hi again Cyprus,
Schools do indeed look at the breakdown in scores -- making sure that you're quantitatively strong as well as able to communicate well through the Verbal section. A good standard for top-tier schools is you want to clear the 80% hurdle in both parts of the test. The schools are unlikely to look down on a retake. If you truly believe this is best year for you to go business school, I would consider my previous advice of submitting your application for R2 deadlines, alerting the school that you are retaking the GMAT, and then following up with your new score. You would want to make sure to take the test within January still to make sure you still get considered for R2.
Best of luck,
Daniel Richards
