Complete set available. Includes answers to correction problems. Bookkeeping Level 3 & Level 2 Courses (Commercial Bookkeeping, Industrial Bookkeeping) These are the textbooks and workbooks from Career College Japan. Only the problem sheets in photo 5 were printed and left on the copier, intending to solve the problems repeatedly. There is a crease on the cover. In the end, I only printed them and never solved the problems. Correction Workbook Answer Key: Photo 6, also creased on the bottom right. There is also a correction workbook, but the correction period has ended. I only obtained the answer key, so the answers are included! Almost unused and in excellent condition. Thank you.
