Well of course, a 730 is a GREAT score. There is no need to waste any time trying to do better. If you think you could get a better score…without investing much time, then you certainly have nothing to lose. But there is no use in investing a TON of time here. The trick to your application will be WORK EXPERIENCE. Leave the GMAT alone—with one additional year of WE you would be able to crack a top 15 program. Without that experience, it may be tough for you to get into a top30 program. Almost all schools will require two years—even if only informally. So consider taking just one more year—it will serve you very well my friend. Sorry to give such advice, I know you are eager to apply! But you are taking a chance…
