Hello,
Well the TOEFL requirements are not a hard cutoff, but if you have an 80, you will need to retake because with a score so low, the schools will be worried about your capacity to communicate in English. So I’m crossing my fingers and hoping you are getting a better score. If it’s 95 and above, then schools ranked 30-50 are fine. And if you DO get an 80, don’t despair, but DO retake and delay your application for a year.
