Over 1,600 schools participate in the event each year.[1][2] The Debate competition is spread over three levels – Regional, Zonal and National Levels. Each school sends two students from each group mentioned above. The topic is only revealed to the students an hour before the actual debate by way of opening a sealed envelope in their presence. This ensures that no pre-written material can be used in the debate. Students are expected to speak for a total time period of four minutes which is followed by two minutes of questioning and rebuttals.
