RE:Yi Li’s application for admission for the undergraduate study
To Whom It May Concern:
The purpose of this letter is to support the application of Mr.Yi Li for the undergraduate study in your college.Yi is a student in my high school physics class.I have known Yi for three years,and we often had chances to discuss many topics of mutual interests,such as …,and so on.I endorse his application wholeheartedly and without reservation.This is based on his solid background in physics that has been obtained from his study in this field for several years.
Mr.Yi Li is also well trained and skillful in dealing with several computer systems,including Windows and Linux.This allows him to be always ready to process and analyze any data of his interests.
Mr.Yi Li takes as well the main responsibility for constructing the new generation of database for our school.This is an extra work assigned to him in addition to his study.He conducted intensive research and experiment and database,together with the necessary computer technique.Now,the database is nearly completed,and the test shows very good performance.Both my colleagues and I am impressed with the achievement he made and the thoroughness of his work.
Considering his performance I know and the program that is offered to lead to a degree in your department,I believe that Mr.Yi Li has found the right place to get undergraduate study,to show his talent in study,and to achieve his academic goals.I therefore trust that Mr.Yi Li’s application for the admission for undergraduate study in your college will be considered with the due seriousness and deliberation it deserves.If I can be any assistance in furthering this consideration please feel free to contact me.
Sincerely Yours,
Dawei Jiang
