[b]students in his class who could keep up with the pace of my lectures. [b]Moreover, he often posed thought-provoking questions during the course. [b]Thus it was natural that I liked discussing with this young man and [b]became familiar with him. The more I knew him, the more I found he was [b]talented at mathematics. As you can see, he got excellent scores on [b]the course. In fact, he ranked No. 1 on this 270 hours course in the [b]talented student class which has 34 intelligent others. [b][b]　　With his outstanding talent and solid mathematical background, he [b]also did quite well in most other courses during his undergraduate [b]study. By the way, you may wonder why his undergraduate scores look [b]not so good compared to other Chinese applicants. It is easy to explain, [b]because he belonged to the talented student class, which were [b]required to endure harder test papers and stricter grading than most [b]other college students did at least at "University of Minnesota". [b][b]　　He even served as Prof. Linda 's Research Assistant for one year. No [b]one could deny his commitment to his job. As a matter of fact, Prof. [b]Linda's electronic lab happened to be neighboring my office and I [b]could always see him working in the lab, either repairing the [b]instruments or helping Prof. Linda collect lab reports. Maybe one more [b]example will demonstrate his commitment more clearly. Once he [b]suggested compiling a FORTRAN program to solve a complicated circuit [b]problem in his class. In order to do that, he had to do a lot of [b]computer work. However, because there were few computers available in [b]our computer lab, he had to wake up at 5 a.m. in winter (please note: [b]"Twin city" is a downtown near the north border of China, so it is [b]pretty cold in winter and the heating system is not working very well. [b]) to ensure the 1st position of the long waiting line for his classmates [b]and himself! At last he and his classmates finished the program [b]successfully with his great efforts. [b][b]　　As to his personality, I would like to say Mr. Caleb is a [b]warm-hearted, honest and upright student. He was always ready to help [b]others. During my lectures, many students got confused at some points [b]and I could always see Mr. Caleb help them explain during breaks. In the [b]meanwhile, I must admit that Mr. Caleb was a bit impatient sometimes. [b][b][b]　　Finally, I would like to conclude my recommendation as follows: [b]frankly, Mr. Caleb is not a genius, but I promise his great [b]intelligence, commitment to work and his kind nature will impress you [b]deeply. Thus I recommend him without reservation for his admission and [b]financial aid to your program. Please feel free to contact me if needed. [b][b][b]Sincerely Yours, [b]XXX
