what about if you got a 690 GMAT score (88%) but the split was 43 Math (67%) and 41 Verbal (92%)?
Depends on many variables - the school you're applying, the demography you're from, the profile you've built et cetera.
On a personal front, I wouldn't give it another shot if I'd score 690. Essays, to me, are far more important than GMAT. So, it's wise to dedicate more time on essays. Again, it's just my view.
