Price: 1,300 yen + tax Ninth edition, first printing, February 27, 2020 The top of the cover is slightly creased, but there are no problems with the contents. I used it for studying, and I didn't see any writing when I flipped through it. (I apologize if there is any writing) Problem section and answer sheets are included. Mock exams 1st to 3rd are included. I think the scope changed after I bought it, but how about it for those who just want to solve problems! Due to storage reasons, it will be disposed of if not purchased by the end of December. It will be shipped via Yu-Packet Post. *Returns not accepted.
