Would-be contestants mailed postcards with their names and addresses to "Jeopardy!". 1,200 teens were selected at random from the postcard entries and were invited to come (at their own expense) to one of four regional test centers ("e.g." Houston, Minneapolis, Philadelphia, and Los Angeles) to take a timed written qualifying examination with the 50 clues read by Alex Trebek on a video monitor at the front of an exam room. Passing scorers were invited back for an interview and mock game using an electronic buzzer system. Their photographs are taken for their files, and they are asked to fill out a short information sheet with interesting facts about themselves that may be later used by Alex Trebek during the interview portion of the show. Selected contestants and alternates were notified that they had been chosen to appear on the show one to two months later. They are then flown to Los Angeles to tape the show. Taping occurs over a period of two days, with the five quarterfinals played on the first day and the three semifinals and two final games played on the second day. Accommodations were provided for the contestants at the Beverly Hilton in Beverly Hills, with taping taking place at the Sony Pictures Studios in Culver City, California.
