Mọi người xem mình có viết đúng ko ạ, nếu sai mong góp ý, và chữa lỗi giúp mình Dear Mr. Dean, My name is Jennifer. I'm currently a second year student of the English Department. I'm writing this letter to tell you about the schedule of the speech contest at the end December. As far as i knew, you has decided to hold a speech contest. And my classmates and I are really interested in it. However, we found that the day which be chosen to celebrate the competition is too near the final examination. So could you please help us to change the schedule of this debate contest to take place at the end of January. How do you think about my opinion?. Please reply to me and let me know if it is possible. Thank you very much for your time in considering this request. I'm looking foward to hearing back from you on this matter. Sincerely, Jennifer
