Sample Quiz Structure

To show how a quiz may be organized.


1. A team shall consist of 4 students

2. Each team will play 3 games as given in the schedule. The second team listed will be considered the host team.

3. It is the host teams responsibility to set the time for the round. The host team is to make certain that the scores are given to the convener in writing as promptly as possible.

4. Students may use paper and pencils, but no calculators in answering questions.

5. Questions will be read in the language chosen by the team (either English or French). When the reading of the question has been completed, the team that is answering the question has 10 seconds to give an answer. At the end of 8 seconds a warning will be given.

Members of a team may confer, but only one member may answer the question and the first answer is the only answer that will be accepted.

6. A round shall consist of 25 questions asked to each team. The teams who are to answer the questions are to alternate. The starting team should be determined by a coin toss.

7. Scoring: A team receives 1 point for a correct answer and 0 points for an incorrect answer. The winning team in a given match is the one with the highest score.

8. If a team wishes to dispute the answer to any question, it must do so immediately after the answer is given and not at the conclusion of the game. Any answer that is disputed should be written on the score sheet and submitted to the organizer who will make a ruling and adjust the score accordingly.

9. Participants in the final round for the championship will be based on the two highest total scores for the 3 rounds played.

A team might win all three games but still not have the highest score.

10. For the final match only (Round 4) 5 pairs of extra questions will be available in the event of a tie. The first team to be ahead after the same number of questions have been asked will be the winner.

There are no points for one team successfully answering a question that the other team has missed. It is suggested that the answer to any question that has been missed by a team be read.
