My best advice for you right now would be to kick the ever-living crap out of the GMAT.
Given that you probably want to attend a finance program, I really think if 720 + is necessary.
It is a real unicorn that gets into a top MBA program without a bachelor's degree comma yet it is possible. If I were you I think I would prepare a statement around why you don't have one, a terrific resume, and request a resume review from the programs that you're looking at.
You do have a really outstanding profile and clear goals. There's a lot to like about your profile and I'd like to just boil it down to the most impressive stuff and put that forth with the no bachelor's thing.
