Considerations include, are you applying to specifically quant- driven schools? This would include both Wharton, Booth, and Columbia.
Pay close attention to the middle 80% range for the schools you're targeting. You really want to be in the middle of that range. Not to say that you can't be towards the bottom of that but there would have to be offsetting entries like you come from a very under-represented country or something.
If you're applying to an elite school like Stanford or Harvard, then it might be worth looking into.
Next would be do you have a quantitative background, have you proven yourself in the quant realm? Do you have transcripts that show you got good grades and statistics business calculus at cetera? If not then I would retake.
Next consideration would be what is your ethnicity. If you are Indian or Chinese you should definitely retake because most of them are great at math and you'll be competing against a tough group. You're competing against your profile not the admissions pool in general.
Good luck and congratulations on verbal
