This is a set of two 2021 editions of Aohon (blue books). They are "Sundai Common Test Practice Problem Collection Mark-style Practical Problem Edition 2021 Mathematics I・A Mathematics II・B". I bought them at a bookstore several years ago and stored them on a bookshelf after use. ☆Original price: 1,188 yen per book☆ ☆This price includes shipping of 230 yen and sales commission☆ 【Size】 (For both books) Approximately 25.5cm x 18.5cm x 2.8cm. 【Image Description】 ①…Overall view of the product. ②…Mathematics I・A condition. ③…Mathematics II・B condition. ④…There are slight scratches and stains on the cover. ⑤…Mark sheets were included, but two sheets have been cut out. One of them is unused and is still inside the book. Also, there is a copy of a mark sheet, so please use it. How about using these for your university entrance exam math studies? Please feel free to ask if you have any questions. (＊＾＾＊)
