No, my-best-score is a special system of TOEFL, combine scores of different parts from different times of taking test. No, I don’t submit sat. I had discuss about language requirement with WM admissions office, they prefer students to get 100 (include my-best- score), but scores close to that are considered, and I know of some people who got in with scores below 100. The reason I gave up taking TOEFL again was that studying and preparing for it was too much torture for me hhh, and it brought me too much pressure, so after getting an ok score, I wanted to break free from it.
