Hi – I would really appreciate some feedback regarding my profile and choice of target schools. Should I be lowering my sights or am I being realistic? My target schools are:
Columbia, Harvard, Stamford, Northwestern, MIT, NYU, Berkley, Booth

I’m from London (where I live and work currently) and will be 29 a matriculation.

Undergrad: 2:1, equivalent GPA is about 3.3 – 3.5, in physics from the University of Bristol, US equivalent is probably something like MIT.

GMAT: 760 (99th percentile overall, V 99th M 96th). I only took this once but I don’t think I did myself justice on the math side as I hadn’t got below 99th on any of my practice tests (I ranked in the top 0.01% in maths during high school). Is it worth retaking this? I am pretty certain I could get higher.

Work experience: 6 years (7 at matriculation) total. First 5.5 years were in finance at several top tier investment banks and for the last year I was a VP managing a team of 5 business analysts looking after finance change functions for structured issued debt.

6 months ago I started my own consulting company and am currently working with another top tier investment bank on a large regulatory reporting project.

Extra-curricular: I have been appointed as one of two volunteer team leaders on Saturdays for 8 hours at one of London’s busiest tourist attractions. In this role I am responsible for ensuring adequate volunteer staffing of the various events and co-ordinating the volunteer activities with the events managers. My team of volunteers consists of 20 volunteers.

In the past I have tutored math and physics to several high school seniors and juniors to prepare them for their national exams.

My long term goal is to be the CFO of a global investment bank. My short term goal is to get a role at director level in finance in such an organization and I want to get an MBA to help me learn to be an effective manager of people and resources as well as gaining some exposure to managerial and financial practices outside of banking.

Apologies for this being poorly written and a bit rushed, I am a bit pressed for time. But any feedback on my profile would be greatly appreciated.
