Have u tried talking to an adviser 'coz I thought I have to take TOEFL too. I told myself that if I have to take Toefl, there's no way i'm going back to school. I emailed my adviser and told him that I graduated fr a high school which English is the medium of instruction. To myself, I'll ask anyway coz there's no harm in trying. Adviser told me to give him a proof like a letter and a high school diploma saying that Engish is used the medium of instruction. I provided him the letter and high school diploma, and then he cleared me for toefl. I didn't have to take it. I'm now taking a class. I don't know your situation but try to talk to an adviser.
