This is a puzzle exam from Puzzle Dojo, available only at the cram school. This is for levels 30-21. I have completed up to the second session of level 29 (with writing). The rest are unused. Please understand this. No name written. This is a non-commercial item, only available to students and not sold in bookstores. With answer key. Highly recommended for those considering junior high school entrance exams. #PuzzleDojo #YotsuyaOtsuka
