Hi! Your GMAT is already strong, especially your quant score - at the 92nd percentile. I am not sure whether taking the GMAT again is going to help you, unless you think you can hold on to that quant score and bring your verbal higher. Given your weak academic record, you might want to consider writing an optional essay where you explain why your grades in college were low, and then present evidence of how you have since changed. One way to show that is by giving details of maturity through professional advancement.
Best of luck,
Rachel Beck
