High school entrance exam preparation set. This set includes problem books that can handle exams with a deviation score of 70 or higher. To prevent any issues, the condition is listed as "slightly scratched and dirty." Please refrain from purchasing if you are sensitive to used items, as these are not new. If you have any questions, please comment before purchasing, and I will answer them. I am decluttering, so I don't plan to list these for a long time. If you're interested, please purchase them soon ♡
