Stacy - please evaluate my profile....

I'm from NY - 26 yrs old - been out of school for 5 yrs and want to get my MBA to make an industry switch.

WORK EXPERIENCE
- 5 years at JPMorgan
- started off in a 2-yr leadership program
- joined the venture capital arm on the finance/accting staff
- during the spinoff of the venture capital arm, my group launched a business where I am now part of a Sales team (recently promoted from sales support to a sales manager)

UNDERGRAD
- 3.75 from a public institution
- honors program

EXTRACURRICULAR
- leadership roles for numerous charity events
- volunteer for a internet start up in California

GMAT sux!!!!!!! (haven't broken a 600 yet!, but I'm trying real hard to change this)

Do I stand a chance at Columbia or NYU?????

I was recently rejected from NYU but I'm not sure if it was solely due to my GMAT score, but would appreciate any feedback that can help since the schools won't give it.

Please advise....
