To give as much flexibility as possible, we have opened the competition for several weeks so that you can decide for yourself when to hold the competition.
Especially if the classes should be divided into smaller groups, you can plan as many rounds as you like. Our recommendation here is that you at least let the students from one level participate together or one after the other.
Within the contest period, you can determine the time frame completely independently. You do NOT have to inform us about it and it does not have to be activated separately anywhere.
