This is a home-stored item. It is the Top Class Problem Collection aiming for junior high school entrance exams. It is for Japanese and Math. Both have a few pages with writing and marking. The writing has been erased. There are about 4 pages of markings per spread. In the Math book, the final review test 1 has been detached. There are erasure marks. I believe it can still be used. I apologize for any oversights. Please understand that this is a used item and check the photos carefully before purchasing. Thank you for looking.
