Original problem set of 57 books containing various question formats. Limited price reduction until December 16th. The list is shown in the third photo, but the books of the items that have been crossed out are not included. Please understand that this is a set of 57 books. Also, the items that are not included are simple ones with a low frequency of questions, so there should be almost no problem. There are signs of use such as tears in the plastic bags and turning marks on the answers, but the problems were copied and used, so I think they are still usable. They cost 1320 yen per book, and over 75,000 yen for 57 books, so it's a bargain. Please purchase with the understanding that these are used items. Thank you for viewing.
