Hello I scored 420 in GMAT. I have total of 4.5 years of experience(2.5 years in Multinational IT company and 2 years as Entrepreneur)

Kindly recommend in which colleges I can apply in USA

concordia university of wisconsin does not need any sat / toefl / gre / gmat score.

Where are you from and what's your final classification for your first degree?

I am from India. I have done my bachelors in computer Sc. And Interested for MBA in US

If you don't want to retake the GMAT and apply to US schools with your 420 GMAT, then Exercise for you.

1) click this link to see several Bschools in USA.

2) Scroll to the bottom of the webpage, copy the school names and then Google search for their websites. Find their average GMAT scores.

3) I randomly checked University of North Dakota MBA, they say that minimum GMAT is 500, and under no circumstances will a student be admitted with a GMAT score under 450. So it might very well be possible that you find no school that might admit you with 420.

Hope it helps,
Ayon

With a GMAT score of 420, you're in the lower 15 percentile of all applicants who took the test. That's not very good - if you were in the bottom 15 percentile of an academic program, for example, you would most certainly fail.

There are some schools that do not require the GMAT - like the Concordia (Wisconsin) program mentioned above, but these would most certainly not be worth the investment for international students. That Concordia program lacks accreditation from AACSB, AMBA, or EQUIS, which is not a good sign.

If you are unwilling to re-take the GMAT, there are very few options. If you've completed a CPA or a master's degree program, some business schools, such as Florida State, will waive the GMAT requirement, so you just would not submit your test results in this case.
