Thanks for your post. Since you are targeting a very competitive field (IB), you would get more mileage out of a 700+ GMAT from recruiters. Believe it or not, some banks even have the gaul to ask what you got on the GMAT in an i-banking interview! As for getting in b-school, I also think a 700+ would make more of an impression than an extra class or two. Since you have CFA level 1, and a finance undergrad, I don't think they would cast doubt on your abilities to handle b-school academics, but the higher GMAT will help their average in theory, which would add instant value to your candidacy. I am not saying your GMAT is bad or you can't get in with it, quite the opposite. Your GMAT is good, but if you could wave a wand and have one wish and the choice is 700+ GMAT or post-baccalaurate class or two, I would choose the 700. Now the risk of course is that you don't achieve the 700 and then it becomes too late to take the class. Welcome to the world of calculated risk, right? You know all about that in financial services. As for other strategy, you will stand out in leadership and community involvement being on boards and volunteering in a way that makes it obvious you are not just fluffing up your resume or application with piffle. Good that you have gotten promotions, but you will come in just under the average amount of WE, so ask yourself how you will stand out amongst others with a similar background but a couple years more WE. I think the answer is in your promotions and being selected on boards--clearly you rise to the top. Work this story up in a compelling narrative, and you should have a good shot. If we can be more helpful, we would love to assist your application prep.
