The top scorer in Korea’s recent tax accountant qualification examination admitted Sunday that he used generative artificial intelligence (AI) and a camera to cheat, reversing his earlier denials after his unusually high marks drew public scrutiny. “I cheated on the tax accountant examination,” Han Won-seok said on the YouTube channel run by his lawyer Lee Don-ho. “I sincerely apologize for the harm my wrongdoing has caused so many people.” Han’s results attracted attention because he answered 159 of the 160 questions correctly in the first-stage tax accountant examination in April, scoring 397.5 out of 400. Three months later, he scored 663 out of 800 in the second-stage written examination and was named the overall top scorer. His exceptionally high scores had fueled online speculation about possible cheating. Initially, he rejected suggestions that he had used AI-enabled equipment.
