Thank you for looking. I purchased this for 9800 yen, but I haven't had time to look at it, so it's been stored away. This is the original, which I have not used. I will quote the comments from when it was listed for sale↓ …………… 2015 Academic Year Course Hama Gakuen Grade 5 Top Level Special Training Arithmetic A set of practical/review tests and calculation tests. Original. * Review Test No. 14, the second page is missing. Calculation Test No. 36 is missing. * Review Test No. 27 has writing in red and blue pencil. * Only No. 37 and 38 are copies. * The answer sheets used by the child will be cut out. Also, the name sections will be stamped over. * There is pencil writing. This is, after all, the original used by a child, so if you don't mind, how about using it for studying at home?
