This is the Advance Arithmetic III course for junior high school entrance exams (equivalent to 6th grade). There are no markings (I apologize if I missed any; they would be erasable). However, there is a sense of use. Please check the images. Please refrain from purchasing if you are concerned about the condition. Junior high school entrance exam textbooks are expensive, so please consider purchasing this at a lower price. Includes a model answer booklet. I will do my best to ship it as quickly as possible.
