I would see if they would agree to an hourly rate to just give your essays another look. At this point all the rest is what it is. But as a college counselor, I have found the most work is needed at the essay level or any other part of the app that needs writing. For a few hundred bucks for an essay editing session I say go for it. I admire that you aim high and have big dreams. Don’t see enough of that either. Good luck???
