This student had to sit 4th- and 5th-year Physical Education to graduate—nothing else. That is, he had finished attending school. And in the staff room the teacher said—I was chatting with another teacher but I heard him—he said, As long as I’m at this school, this student will not pass. And I said, Is that so? OK. And that year I implemented an additional examining board, and the student signed up for the other board, of course, and he passed.
And I thought, I have to do this for all the subjects, and I got the idea by a fluke.
