At the request of Mr。 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&apos 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。
