I could give you a long list of B schools which will accept you now. If you’ve got money to burn-- go for it. But assuming that your “ambition” is going to get you in to Wharton- who do you think applies to Wharton- the unambitious?
Take the GMAT. Score in the 99th percentile. Work for two years and cultivate strong relationships with your peers, boss, and bosses boss.
Done. This is the formula. You don’t want to hear it? That’s on you. Every B school on the planet will be happy to read your application and cash your check. Does it mean you are getting in to one of the top schools??? The leap of faith you are hoping and wishing for? Doesn’t sound like someone who understands and calculates risk very well, which is a critical component of the MBA curriculum!
