Dear Sir or Madam,
I am a native German speaker and was raised bilingually at home and in school.
Due to bilingual classes in history, social studies and geography, I speak English fluently and acquired very wide range of vocabulary, which is essential to any translation job.
I graduated from high school in March, with the highest GPA of 1.0, which indicates As in all classes in Germany.
If you wish, I will send you copies of my high school diploma and the certificate that confirms my successful participation in the Bilingual Wing of my school.
Yours sincerely,
A. Saenger
