For many graduate students of physics the written qualifying examina-tion is the last and one of the most important of the hundreds of grueling examinations that they have had to take in their career. I remember vividly my own experience in 1947 at the University ofChicago. After the quali-fying examination, I knew I was finally free from all future examinations, and that generated a wonderful feeling of liberation and relief. Be that as it may, the written qualifying examinationdoes serve a useful purpose, both for the faculty and for the students themselves. That is why so many universities give these exams year after year in all parts of the world.
