Dear Mr Brown,

>accomodation which you provide on a English course. I have been
>learning English for ten years but my level is not so good. I have got
>a problem especially with grammar.
> I have been working for a big company for a long time. One month ago
>I was promoted on a convasser position (what is a convasser--jk bedzie po polsku?)
My vocabluary and pronounciation are quite good but my weak point is (
grammar. Therefore I am interested in a
>course which solves my problem. It would be great if it would be
>led by a native speaker and held in a small group. I am wondering
>how much the course could cost and whether there are any discounts
>available.
> I would be pleased if you could send me all this information on my
>mail.

>I look forward to receiving your reply.

>Yours sincerely
