The Avenue des Champs-Élysées, in Paris, will be transformed this Sunday into a classroom as far as the eye can see. From 4 a.m., 1,700 school desks - a little higher than the CP model - were arranged in strict lines.

A giant screen of 102 m2, representing the blackboard, has also been installed. Thousands of four-colour pens and copies were brought in for distribution to participants. Each dictation will last between 20 and 25 minutes. If you get less than four mistakes, you can have your copy stamped by a teacher.
