This is a set of 5 items for care service administration: a textbook, a service code table, a practice problem book, an answer key with explanations, and receipts. Original price: 10,500 yen total I purchased this, but it has been stored at home unused. I am offering it for sale in hopes that someone can use it. Please be aware that there are writings in pencil (and some in red ballpoint pen) and markings with a highlighter throughout. In my personal opinion, some pages have stains, but they are not on the text, so they should not interfere with your studies. I have erased my name on the back with a marker. The receipts include approximately: Form 2: 8 sheets Form 3: 3 sheets Form 4: 2 sheets Form 5: 2 sheets Form 8: 2 sheets Form 9: 2 sheets Form 10: 2 sheets If you can accept the above, please consider purchasing.
