The next class is something in between - "brainstorming" doesn't work very well, but they work well in a group. From this, I concluded that a failed class does not necessarily mean bad preparation. It is a combination of preparation and, above all, the attitude of the students. It was worse with the ninth graders. According to all the teachers, the worst class in the school.
