Sidney Cahn and Boris Nadgony have energetically collected and presented solutions to about 140 problems from the exams at many universities in the United States and one university in Russia, the Moscow Institute of Physics and Technology. Some of the problems are quite easy, others quite tough; some are routine, others ingenious. Sampling them I am reminded of the tripos questions of Cambridge University that I had spent so many hours on when I was an undergraduate student in China during the years 1983-1942, studying such books as Whittaker's Analytical Dynamics, Wthittaker and Watson's Modern Analysis, Hardy's Pure Mathematics, and Jeans' Electricity and Magnetism.
