"World Heritage Certification Official Past Exam Questions Collection 1st and 2nd Grade ‹ 2023 Edition ›" World Heritage Certification Office / NPO World Heritage Academy I'm selling this because I passed the exam. There are no markings, but there are signs of having been opened and some minor wear and tear from use. There is a pen mark on only one page. (Please check the third photo) For those who can understand and those who understand that this is a used item, thank you for your consideration.
