Download Round Two – Lightning Round

Round Two – Lightning Round
• Round two consists of 30 questions
• Each individual team will read the questions and possible
answers as they appear on the screen. No moderators and no
individual team judges will preside in round two.
• A team member will record the team’s selection of an answer on
the round two score sheet.
• The length of time the question/answer which appears will vary,
depending on the length of the question and possible answer. A
countdown timer will appear on the screen that has been
calculated and adjusted according to the question/answer length.
• Slides will not be reviewed or repeated until the end of the
round two, after all of the4 teams have remitted their answer
sheets to the Master Judges.
