blue-bird, I have a question for you. Last time you mentionn that you can send your TOEFL score before starting classes in September, right? Can you tell me which school are you applying for? You have already given all documents except the toefl score to the school, how can they extend the deadline. We should ask the advisors of the schools? But some of them say " No way"  .

I am very sorry that i could not answer your question, but can you give me your answer?

Thanks a lot
