Practical Mathematics Skills Certification, Su-Ken, Past Questions Collection, Grade 6, Japan Mathematics Certification Association Price: 880 yen (tax included) Editor/Publisher: Japan Mathematics Certification Association Publisher: Maruzen Publishing There are scratches and folds on the back cover and the back cover of the separate answer booklet, and there are pencil and red pen marks in several places in the main text, so please consider purchasing if you understand this. Also, since both items have been stored at home, please check the photos for the condition and make your decision. I will wipe the front and back covers with a disinfectant sheet, pack them in a plastic bag, and ship them via Yu-Packet Post. I am also selling these on Rakuma and Yahoo, so please forgive me if they become out of stock due to a time difference. In addition, I have listed over 100 items, so if you are interested in any other products, I will also sell them in a bundle, so please feel free to comment. #Practical Mathematics Skills Certification #Su-Ken #Arithmetic Test #Key Point Review #Past Questions Collection #Grade 6 #Japan Mathematics Certification Association #Maruzen Publishing #Latest Edition #Question Collection #Reference Book #Mock Exam #Book #Certification
