Top-Class Problem Collection for Aiming for Junior High School Entrance Exams Arithmetic - Grade 4 Elementary School - Features: Includes tests for assessing academic ability - Target Grade: 4th Grade Elementary School Thank you for viewing. I haven't used it much since I bought it. However, since my child may have used it without my knowledge, I checked for any writing, but I couldn't find any. (I apologize if I missed anything due to my amateur inspection.) It has been stored for about 3 years, and the white parts of the cover appear to be discolored. However, I think there is no problem in using it. I look forward to your purchase if you don't mind. Please refrain from purchasing if you are looking for a perfect item, as this is a used item. I do not offer discounts. Also, I do not hold items. Thank you for your understanding regarding the above points.
