Well what are you planning on doing with your TOEFL score? If you are planning on going to school in an English speaking country, you'll have to call the school to check. Likewise if you are trying to get certified.
I work mostly with students preparing to go to university in the US. As a result I spend a lot of time talking with admissions officers and various schools. Almost NO schools require a TOEFL score (or anything else) from students who can prove that they went to high school (or college) where the primary language of instruction was English. They merely have to provide some proof of this (nothing fancy, usually just a letter from the school).
