This is a booklet from Hama Gakuen's Shichikan Tokkun (Seven Crowns Special Training). For Grade 6 boys aiming for the most difficult junior high schools - Entrance Exam Pass/Fail Judgment This is a booklet for the Shichikan Tokkun. It includes the supplementary materials for the 2nd and 3rd sessions of: Arithmetic A, Arithmetic B, and Science. A total of 6 books. It includes problems and answer explanations, so I think it will be helpful. I don't see any names written on it or any writing inside. (I apologize if I missed anything.) The booklets are B4 size and large, so they will be folded in half for shipping. Please understand. Thank you very much.
