Payroll Calculation Practical Skills Certification Exam, Level 2, 2025 - Study Set ・Study Guide Textbook ・Calculation Problem Examples Collection (with answers and explanations) ・Reference Materials ・Slide Collection The Examples Collection was used about twice. It's in good condition with no writing. The Study Guide Textbook and Slide Collection are new and unused. The Study Guide Textbook contains more detailed information than the official textbook and is a must-have for those working in the field. I will sell this to someone who understands that it is a home-stored item.
