These are textbooks and reference books for review purposes, not for individual sale. This is a set of two. *No accessories such as test creation materials are included. *Everything shown in the photos is included. Please be aware of whether these books are the ones used at your school or not. Even if they are different from the books used at your school, they are school-exclusive books, so they are good books to use for self-study. No pets, no smokers. Please understand that these are items stored at home and may have scratches, wrinkles, and corner bends on the cover. Separate answer books and notebooks may have been stored inside the main books, and those parts may be expanded. It shouldn't affect the use much, but please purchase only if you understand. Please understand that if there are any inspection errors other than "obvious writing," it is due to amateur inspection. Individual set purchase is OK.
