Hi Erabm1439s,
With a 700/Q49, you've already proven that your current 'academic abilities' are really strong. The phrase "need to focus on my application" is incredibly VAGUE. What parts of your application needed work? You seem to understand that your essays needed work (so you worked on them), but are those essays as fantastic as they can be? And were there any other SPECIFIC aspects of your application that needed improvement? Highly-competitive Business Schools tend to look for strong OVERALL applicants, so you really have to examine every aspect of your profile/application. If the people you've already talked to cannot point to specifics, then you need to keep looking and find someone who will.
