Hi, my name is Alex, and I am from Ukraine, I would like to know, whether some b-schools are admiting to study MBA students with a score of TOEFL 77? At the moment my TOEFL iBT result is 77 (Reading 23, Speaking 20, Writing 22, Listening 12).
If you know any accredited b-school which accepts such toefl score, I would be gratefull for you answer

I searched on line and found: http://whichuniversitybest.blogspot.co.uk/2009/11/toefl-ibt-score-requirements.html Middle Tennessee State University jumps out as a fit for you.

Thank you Duncan very much, just one b-school accepting 77 score? The major part of schools require 79 at least I know, but I suggest that there are some more schools.
Do you know some resources where i can search b-schools by TOEFL requirements?
Thank you in advance for your reply

No, I took a few minutes to look online and that's all I could find. To be honest, I really think you should improve your score. You will find it very hard to do the reading needed and to play an active role in classroom discussions and group work. Aim for 90.

Also, look for programmes that are designed for people with your level of English, like this one: http://www.st-andrews.ac.uk/elt/foundation/businessandenglish/
