Dear SirMadam:

　　I gladly recommend my student Mr. Yi to you for his application to your graduate school program.

　　Mr. Yi enrolled in my courses of “Digital Control System”“Optimization Theory” during his senior year. In the former, he got a good score of 86/100ranked within top 5% of the class. In the latter which was opened for graduate students, he was one of the only three undergraduates who took this course. Throught the period of instruction, I found him an inquistiveattentive person. He always concentrated on my lecturesabsorb knowledge profoundly. Although some of the assignments were somewhat difficult to the average students, he could solved them completelycorrectly owing to his logicalanalytical thinkingthe clear conception to the theory.He also impressed me in the final project developing a program to resolve the free variable optimal problem. He thought deeplydid it skillfully, so the program could work very well even for the special cases (like cycling…) but still economicallyeasy to read. So I gave him the good scorewas better than many graduate students.

　　Besides, He also took a cluster of courses in ControlSystems Theory in his juniorsenior yearsalways got good scores.Upon my observation, Mr. Yi has been fully prepared to undertake a Master in your institute in the controlsystem fields. I am confident that with the ingenious learning abilitydiligent attitude that he has shown in thhe courses, he will be able to perform outstandingly even in a highly vigorous program. I have no hesitation in recommending himhope that you will consider his application favorably.
