Cover letter on English language proficiency

Hi,
In order to be accepted into the university I am applying to, I have send in English language proficiency proof. Preferably by IELTS or TOEFL results, but it is also possible to write a cover letter explaining why I think I shouldn't have to.......

Could you check this out and tell me if you think it's ok? I would appreciate it !!


To whom it may concern

As all non-native students must demonstrate their English proficiency in order to get accepted into (Xx) University, I kindly ask you to exempt me from sending in IELTS or TOEFL results, and treating this letter as proof that I am a fluent English speaker.

From my youngest years I have been brought up in an English speaking society.
Since the age of 5 I have attended an Australian primary public school in Sydney.
I have learnt English the natural way, but going to school and playing with other Australian kids. I believe young children learn languages the fastest, and I have been lucky enough to have the benefit of learning good English this way.

Later on I have lived in (Xx) where I have attended the International School of (Xx).
I have improved my English in all academic matters. I have learnt problem solving and critical thinking, English has become the language in which I learned to think in.
As a main language at high school level, it is also been the language in which i have done all my high school exams, that I have passed with good results.
I believe that, even tho my mother tongue is (Xx), I should be treated as a native English speaker.

I kindly ask you to look over this matter and exempt me from sending in other proof of language proficiency.

Yours sincerely
....
