Stretch: Booth, Columbia, Sloan, Kellogg, Tuck -- you'll be a stretch at these schools because you'll be up against so many other finance guys; not a huge stretch, but enough of one that you'll need some luck on your side and where you'll need to apply to a few sweet spot schools (see below) if you really want to play the odds
Sweet Spot: NYU, Haas, Duke, Darden, Michigan, Cornell, Yale, UCLA
Safety: any school outside the top 16
Which 5-6 schools you choose to apply to is more a matter of personal preference.
