Dear officer,
Hi,
I am XXX.I received a denied letter from XXX recently. Thanks for your time to review my application,although I am sorry to hear this decision.
I really want to study XXX(申请专业) at XXX(申请院校). XXX学校是XXX(夸学校). I am really looking forward to being offered to continue study at XXX(学校),and improving myself for it. (粗略提一句自己与申请项目的匹配点). Therefore,I would like to ask if there is still any incomplete part in my application,or may you tell me if there is any part I still need to improve for, please? If you may give me any further advice on my application, I am more than willing to improve to meet the requirement to study.(接一点简略的夸学校)
I appreciate your taking the time to review. Thank you.
