The semi-final exam is used as the basis for selection of the 20 members of the U.S. Physics Team. These students, from schools all over the United States, travel to the University of Maryland-College Park at the end of May for the annual U.S. Physics Team Training Camp. There they engage in ten days of intense studying, testing and problem solving.
