I think there is time to improve your score in the next month if you really buckle down and strategically map out a good study plan. I think you should reevaluate when you're closer to the test. However, I think the better questions is not "should I drop August?" but instead "should I add October?" And the answer is yes, add October. So long as you aren't applying to Canadian schools, most American law schools take your highest score. It's okay if you take it twice.
