Check grad school shopper (http://www.gradschoolshopper.com
) to see a school's minimum TOEFL requirements. Ohio State has a minimum of 79, so there are respectable programs for which you are not below the minimum cutoff. It seems like a lot of schools have a minimum of 550/213/80, which you are close enough to that your application might be looked at, but it will still make admissions anywhere difficult. I don't think anybody has a list of schools with a TOEFL minimum of 79 or below, so you'll have to do your own research here and check the requirements school by school. Do you have any research experience? If your application is otherwise strong, remember that you can always take a year off and try and improve your English then try again next year. All of your other scores will still be valid. Even if your TOEFL score is at or slightly above a school's minimum cutoff, it's still going to be hard for them to accept you, especially if you plan to be funded with a teaching assistantship. Remember that you have to understand others and they also have to understand you for you to be successful here. If you want to study in a foreign country and aren't good with the language it makes it difficult for everyone involved.
