I went to the certification test held on February 18th. This is the 8th time I tried it. I was unable to attend the fourth session due to emergency hospitalization. This time, I was preparing for a score of 100 points, but when I came home and opened the HP after 1 o'clock and checked the answer, it was far from perfect score. I'm sorry. But as you mentioned in the questionnaire, next year we will challenge in the sense of checking various knowledge of Chuo-ku. Next time, I will walk around Chuo-ku aiming for 100 points. I think it was a very good problem, but what was the result of those who were challenged?
