A science study guide for 6th graders aiming to pass the Nada Junior High School entrance exam. - Title: School-Specific Pre-Study Series Science Year 6, Part 2 (Lower Volume) - Publisher: Yotsuya Otsuka Thank you for viewing. This was purchased for home study, not for use in a cram school. The answers were checked by a parent, and areas where the student struggled have been lightly marked with a 2B pencil. The answers to the problems were written in a notebook, so there are no markings on the questions themselves.
