Hello

I am 25 years old and below is what my profile looks like

GMAT- 570, 610 & 660 ( Q46, V35)
GPA- 3.5
Extra Curricular- Have been active in sports in school,part of CSR & Green Initiative at the company level, Volunteer work in AIDS awareness workshop.
Work Ex- Process Lead in Infosys ( former designation was Associate Consultant ), significant leadership experience- have lead teams across different domains, 4 promotions/progression in 5 years

Aspirations: Work for a Management consulting firm or company in New Media like Google, Facebook, possibly in US.

Some Additional Points:

Have been part of a failed start-up ( tried launching a language company with a friend, we had to give up in 5 months because of lack of funding & other reasons )

Have some international experience & have traveled to 3 countries in the last 4 years

Questions

1. What Business Schools do I have a chance in? Would giving the GMAT again help, I think I can score better ( 700+)
2. Any possibilities of getting into a B-School in Chicago/near Chicago ( that's where I want to work after MBA ).

Also will some professional help in showcasing my overall profile can I overcome a relatively low GMAT score for an applicant of a very competitive pool?

PS- Already have an offer to join Rotterdam School of Management.

Kindly advise

Regards
Rachit
