I intend to work in the developed financial markets for 5-7 years. I will use this experience to start my own firm in India which would provide financial consulting in the field of international trade transactions / foreign exchange risk management.

My questions are:
1. Overrepresented pool:
I know that Indian IT Male is the overreprented pool. But is the Indian Finance Male aslo an overrepresented pool?

2. What are my chances at these schools:

CMU, Cornell, Virginia (Darden) Texas McCombs, Rice (Jones Graduate School), Rochester (Simon), Nanyang Business School.

3. Taking GMAT again:
I am very much interested in NYU (stern Business School) and Duke (Fuqua School of Business). I am aware that my GMAT score is below the average score for both the schools.
Till date, I have taken GMAT thrice. My score are
1st Attempt: Mar 2008 - 660 (Q45 V35)
2nd Attempt: May 2008 - 640 (Q44 V34)
3rd Attempt: August 2009 - 660 (Q47 V 34)
My problem areas ar RC and SC. If i improve my problem areas and am able to secure a 700 score, will my previous attempts be seen as a negative (Considering it would be my fourth attempt)

4. Leadership roles:
In both jobs, i have a profile of sales and trading and have individual targets. Hence I have never managed / led a team. Would this be taken as a negative.
