There were pencil markings as shown in the image, which I erased. Also, I corrected printing errors from the publisher with a ballpoint pen. I apologize if I missed any markings or overlooked anything... The answers were written in a notebook, but please be aware that there may be other writing. For those heading into the real thing, How about it for 4th and 5th graders who are considering taking junior high school entrance exams? Thank you for looking.
