Dear Miss Kowallska,
Kindly check the transfer of 14 November, because in this day we would go to the lecture by Professor Sommer on the English-speaking countries. We are confident that it will be for us a very valuable and helpful in further studies. We wrote a test at a later date.
Sincerely, classe 1a

Dear Miss 'Kowallska,' (sprawdz jak to nazwisko sie pisze)
Kindly check the 'transfer' (nie rozumiem o co tu chodzi) of 14 November, because 'in' ON this day we 'would' (zly modal) go to the lecture by Professor Sommer on the English-speaking countries. We are confident that it will be for us a very valuable (ale co?) and helpful in further studies. We 'wrote' (zly czas) a test at a later date.
Sincerely, 'classe' (ortog) 1a
