A set of the official question book and guidebook for the World Heritage certification. I purchased these about two weeks ago and am selling them because I passed the Level 3 exam. The books have covers on them, and there are no markings such as highlighting, so the condition is quite good. I am also open to price negotiations. - Title: World Heritage Certification Level 3 & 4 Official Question Book 2025 Edition - Title: 100 World Heritage Sites - Barcode: 978-4-7991-1234-5 - Barcode: 978-4-7991-5678-9 Thank you for looking.
