Dear Mrs Johnson,
I am so happy to inform you that, from all my classmates in the 8th form, I obtained the highest qualifications at the National Evaluation exam last week. My letter of interest in attending the courses at the National Linguistics College has just been accepted, so I will pursue my dream of studying the universal literature and civilisation, as well as foreign languages. Your contribution to my knowledge and interest in English has been significant and I want you to know how much I appreciate your hard work and dedication.
Thank you! I hope we will meet and talk about my new experience at this college one day.
Kindest wishes!
Leonard
