4d - In short, you need not do anything. The AWA sectional score has no bearing on your overall admissions. Typically, a score of 4 or above is considered acceptable by most MBA programs. Furthermore, if you have a decent verbal score, the modest AWA score will likely have no impact. By the way, congratulations on scoring a 730 on the GMAT. If you still have any doubt, you can individually reach out to the admissions committees of your target schools, but I do not think doing so is necessary.
