The man who scored the highest in South Korea's tax accountant exam this year admitted to cheating using a small camera, mobile phone and artificial intelligence.
Han Won-seok, 34, said in a video posted on his lawyer's YouTube channel on Sunday that he used electronic tools and artificial intelligence in both stages of the examination.
"I would film the questions with a small camera and send them to the AI," he said. Then I would see the answers on my mobile phone.
In the first stage of the exam, Hahn scored 397.5 out of 400 marks and gave a wrong answer to only one of the 160 questions. This almost perfect score raised questions.
