Xizhen Chen， my former student in the Department of Computer Science， Beijing Univ. of Sciences， I am glad to write this letter furnishing my evaluation of his academic aptitude for your reference. Mr. Chen is interested in your graduate program in Computer Science.
I came to know him in September 1987 when Mr. Chen enrolled in my class on FORTRAN IV Programming， a three semesters' course. In the class he was one of the most outstanding students. At the semester final he earned a high grade of 81， which should be "A" according to our grading system. I also found him good at other studies.
After the class， he had personal talks with me several times. He indicated a great interest in computer hardware， In my opinion， Mr. Chen has a potential in Computer Science， which can be further developed.
In view of his previous achievements in this College， I am firmly convinced that Mr. Chen will make a successful graduate student. Your favorable consideration of his admission will be highly appreciated.
