Dear Sir or Madame,

During my high school days I finished all the classes in English that were provided to us.

From the course A to the advanced course C. I did the final exam of the B course in the beginning of the second year in High school, I felt I had the knowledge to pass the grade without attending the classes and so I did.

I also studied English in during the summer of 2000, I went on a language learning exchange, and I lived with a Maltese family. I had classes from Monday too Friday. We were about 100 students from , We did an English test on are arrival and then we got divided up in two groups. Advanced English and common English, I was placed in the advanced group. At the end of the summer we got to do a final test, it was very advanced and ranked among the university tests. I got 76 question right out of 100 and got an A on the test, got the fourth highest score among 100 students. . I am fully confident that I can handle this.

Yours sincerely,

Dear Sir or Madame,

During highschool I did all available courses in english, from A to C. In the beginning of second year in school, during B course I thought classes were easy, so I decided to take the final exam right away, and finished with good results.

I also studied English in Malta during the summer of 2000, I went on a language learning exchange, and lived with a Maltese family. We were about 100 students from Sweden and we had classes from Monday to Friday. Everybody had to do an english test on arrival and then we got divided in two groups, common and advanced English, I was placed in the latter. At the end of summer everybody did a final test, which was at an advanced level and ranked among university tests. My results was 76 question right out of 100 and grade A. I got the fourth highest score among 100 students.

I reckon you will find that with my skills in english I will have no problem keeping up pace during class.

Yours sincerely,

tell me what you think
Hello, as this appears to be a test of your English skills I am hesitant to help you too much.

However I'll give you a little tip: Madam is English while Madame is not.

Also, English is a proper noun, and so should always start with a capital E.
