Thank you for viewing! m(_ _)m This is a 5-piece set of key points and countermeasures. Answers are also included in a separate booklet. ⚠️ Math and English have been used for about 30 pages. Also, the name on the back has been blacked out. As you can see in the second photo, there are also some scratches and stains. ※ Science, Social Studies, and Japanese are all unused.
