Knowledge Bowl is usually a power competition in which team groupings are rearranged after each round on the basis of their total points accumulated. The written round is a multiple-choice exam taken by each team as a whole. Results of this round are used for seeding teams in the oral rounds. Oral rounds involves three teams per room and uses an electronic lock-out device system. A reader presents the questions, and a team member may buzz in as soon as he or she chooses. If they miss a question, nothing is deducted, but the other teams then may try to answer the question based on who buzzed in first. The winner is the team with the greatest number of points at the end of the meet.
