Have you considered taking the GMAT test again? The reason I mention this is, for example with Chicago Booth, the average GMAT score is a 720 with an 80% range of 660-760. This means that if you applied with your score, you would be in the bottom 10th percentile. This does not mean you would not be accepted, but it is not a preferable position to be in.
Your GMAT score is self-reported on your application, so admissions teams will only focus on your highest score.
Hope this was of help.
