I'm considering getting my MBA under a specific set of conditions; basically that I get into one of a handful of schools (NYU, Yale, Harvard, Wharton, Columbia, MIT, and Dartmouth) although I'm open to other options (close to NYC) that have a reasonable chance of getting me placed. My profile is overall fairly weak (see below) with the open question of a GMAT score.
I'm a historically strong standardized test taker (1410 SAT ~95th percentile, no test prep; 168 LSAT 96th percentile, but skipped an entire logic problem for so likely a outlier low score) so there is a possibility that I could home run the GMAT (mid 700s). Either way, I'm fairly confident I can achieve a 720+ score that seems to meet the minimum threshold most top places. The problem is, I've not been able to study adequately on my own and would need to take a prep class at a cost of about $1.5k to get my score into that kind of shape.
GMAT: 720+
GPA: 3.4 (call it a top 100 undergraduate business school although it was top 50 when I went; well known public university anyway)
Major: Accounting; Minor in Leadership and Ethics
Work Experience: 6 years at a super-regional bank doing middle-market leveraged debt (particular group within the bank is an industry leader); several promotions including an executive prep program (1st ever person selected) and competitive credit training program (top 10% of class); will either be 7 years at matriculation or possibly a year at another firm
Extracurriculars: Nothing spectacular since school; various volunteer positions including some local soup kitchens, NGO's, and some things through my church; I did a Semester at Sea study abroad program in college, that's been a wild card on a few interviews that people like, not sure how much an admission's committee cares
Age: 30 at matriculation
Recommendations: Nothing spectacular although I might have a personal network in at Wharton (which is a very long shot with my profile anyway).
I'm concerned that other aspects of my profile will hold me back too much regardless of other considerations; particularly my old age, poor work experience, and average GPA. I'm willing to spend the money on the class of course, but I'm hesitant to do so unless I can realistically expect to get admitted somewhere with a ~720 GMAT score.
