Don't understand why people here put so much weight on GPA. MBA is career focused so the schools are more interested in what you did and plan to do in the work place. For GMAT if time permits you can take it again and if you go above 750 you might stand a better chance, however the backbone of a strong application package is always essays. Excellent essays just stand out from the rest. So if you are time-constrained my suggestion is to put everything else aside and focus on your essays. It takes time and it will worth the time.
I don't know what your objectives are, but I don't see why M7 are not reachable. Once again the WE (and the way you present it) carries a way more weight and I can tell little from your post. Good luck anyway.
