Please note that prices may fluctuate due to market conditions. This is a set sale of textbooks and workbooks from the Chamber of Commerce and Industry Computer School. These are study materials for the Nissho PC Certification, including Excel, Word, and VBA. Typing materials are also included. Everything shown in the photos is included. I no longer need them as I took the course and obtained the certification. While the certification is lifelong, the study materials are no longer needed, so I am selling them. There are many handwritten notes in the materials from when I took the course. There are notes, checkmarks, and lines drawn throughout. There is also evidence of use. Please only purchase if you understand that this is a used item with handwritten notes. Not sold separately.
