The registration fee is 10€ per student. Included is the full access to the app The Big Challenge Play, the Class Activities and the CLASS Challenge as well as the contest itself. Everyone gets a prize and lots of extra prizes are sent to each school. 

The contest is financed solely by entry fees, and organisational costs have risen sharply in recent years (cost of paper, fuel, labour, etc.), which is why we have had to rethink our pricing structure. In the past, the contest and the Class Activities were separate and had separate fees; this year, the registration fee contains all elements of The Big Challenge for a truly engaging experience throughout the entire school year.
