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.
