The annual Jeopardy Online Test is being held this week, beginning this evening at 8 pm ET. This is a good opportunity for people who want to be on the show but can't travel to Los Angeles for the regular auditions. There will be separate online tests tonight, Wednesday and Thursday. You can only participate in the test once a year so you have to choose from one of those days.
Pre-registration is required. Then you have to log on to the official Jeopardy site 20 minutes before the test begins. It's not an easy test, which fits with the difficulty level of the show. You have a very limited amount of time to answer each question so you won't have time to be running online searches for answers. The passing score is not specified. Those who pass will have a shot at getting invited to one of the in-person auditions at various cities across the U.S. You would have to pass the live audition to have a chance at becoming a contestant on the show.
